This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Referring to fig. 1, 2, 3 and 4, an embodiment of the invention provides a device for detecting the engagement depth of a contact of a circuit breaker. The breaker contact engagement depth detecting apparatus includes a housing main body 100, a plurality of insulating cartridges 200, a plurality of driving members 300, and a plurality of displacement detecting members 400.
the insulating cylinders 200 are disposed on one side of the rack body 100 and are disposed in one-to-one correspondence with the fixed contacts in the high-voltage switch cabinet to be detected.
The driving members 300 are disposed in the insulation tube 200 at one end thereof far from the rack body 100, correspond to the insulation tube 200 one by one, and move in an extending direction of the insulation tube 200 when being pressed from the outside.
The displacement detection parts 400 are fixedly arranged in the insulating cylinder 200, correspond to the driving parts 300 one by one, and are elastically connected with the driving parts 300, and are used for detecting the relative displacement of the driving parts 300 relative to the displacement detection parts 400 and determining the engagement depth of the breaker contacts according to the relative displacement.
In this embodiment, the rack main body 100 is designed based on the external dimensions of a simulated switch trolley in actual operation, the insulation cylinder 200 is designed based on the external dimensions of an actual moving contact, and is molded by using a DMC (bulk molding compound) material, and is a mounting seat of a sensor and a cavity cylinder for moving the driving part 300, and then the driving part 300 and the displacement detecting part 400 are provided in a matching manner, so as to form the moving contact and fixed contact engagement depth measuring trolley. When the portable switch cabinet is used, the portable switch cabinet can be shaken to the working position of the KYN cabinet by imitating an actual switch trolley, and the static contact on the KYN cabinet pushes the driving part 300 to perform reciprocating piston motion in the insulating cylinder 200.
It can be understood that after the engagement depth detection device for the circuit breaker contact is switched from a test position to a working position, a fixed contact in a KYN cabinet and the insulating cylinder 200 form a movable connection design, a movable contact pushes the driving part 300 to move along the extension direction of the insulating cylinder 200, and then the relative displacement of the driving part 300 is detected by the displacement detection part 400, so that the engagement depth of the circuit breaker contact is determined according to the relative displacement of the position, the direct measurement of the engagement depth of the contact is realized, meanwhile, the problem of large measurement error caused by the reasons of blocking realization and the like when the reading of surface engagement traces is utilized is avoided, and the measurement precision is improved. In addition, the engagement depth of the contact is detected in the KYN cabinet by using the circuit breaker contact engagement depth detection device, so that the static contact does not need to be detached from the KYN cabinet, and the workload and the risk of possible equipment damage are reduced.

In this embodiment, the displacement sensor 410 is a linear displacement sensor 410. The linear displacement sensor 410 adopts a variable resistance type sensor, the resistance value of the measuring range is 0-5 k omega, the output signal is 0-5V electric signal, and the measuring precision is 1%. In order to meet the requirement of repeated measurement, the selected linear displacement sensor 410 is provided with a movable core rod which has a self-resetting function, and the displacement sensor 410 automatically resets the driving part 300 to the initial position in the process that the measuring trolley exits from the working position.
in one embodiment, referring to fig. 6, the displacement detecting unit 400 includes a pressure sensor 430 and a second data processing circuit 440.
The pressure sensor 430 is fixedly disposed in the insulating cylinder, and is elastically connected to the driving member 300, and is configured to detect a pressure applied to the driving member 300.

It can be understood that the driving member 300 is elastically connected to the pressure sensor, after being pushed by the fixed contact, the driving member 300 applies a pressure to the pressure sensor 430, the greater the pressure, the greater the elastic deformation between the driving member 300 and the pressure sensor 430, and then the relative displacement is determined by the second data processing circuit 440. Specifically, the magnitude of the relative displacement may be directly searched according to a preset mapping relationship between the pressure and the displacement and the mapping relationship.
In one embodiment, the displacement detecting member 400 further includes an elastic member (not shown) disposed in the insulating cylinder 200, and one end of the elastic member is fixedly connected to the driving member 300, and the other end of the elastic member is fixedly connected to the pressure sensor 430. It can be understood that, by arranging the elastic component, the driving component 300 can generate relative displacement with respect to the pressure sensor 430, so as to determine the depth of engagement between the moving contact and the stationary contact according to the relative displacement.

In one embodiment, the side of the driving member 300 facing away from the sensor is in the same plane as the edge of the insulating cylinder 200.

When the side of the driving member 300 facing away from the sensor is in the same plane as the edge of the insulating cylinder 200, that is, the initial position of the driving member 300 in the insulating cylinder 200 is located at the 0 position in the insulating cylinder 200, the initial position of the driving member 300 does not need to be considered in the calculation process, which is beneficial to simplifying the data processing process.
In one embodiment, the shape of the cross section of the driving member 300 is the same as the shape of the cross section of the cavity surrounded by the insulating cylinder 200. It can be understood that when the shape of the cross section of the driving member 300 is the same as the shape of the cross section of the cavity surrounded by the insulating cylinder 200, the driving member 300 can be ensured to move only along the extending direction of the insulating cylinder 200, and displacement in other directions in the insulating cylinder 200 can be avoided.

in one embodiment, the device for detecting the engagement depth of the contact of the circuit breaker further includes a storage battery 600 disposed inside the rack body 100, electrically connected to the displacement detecting unit 400 and the digital display meter 500, respectively, and configured to supply power to the displacement detecting unit 400 and the digital display meter 500. In this embodiment, the power supply output by the storage battery 600 is DC24V, and the measurement trolley must enter the KYN cabinet to be inconvenient for external power supply during operation, and meanwhile, the storage battery 600 is arranged on the measurement trolley for convenience of use when no external power supply is available.
In one embodiment, the device for detecting the engagement depth of the contacts of the circuit breaker further comprises a power management module 700 electrically connected to the power supply for adjusting the magnitude of the charging voltage through dynamic monitoring of the voltage, current and capacity of the battery 600. It can be understood that the charging voltage is adjusted by dynamically monitoring the voltage, the current and the capacity of the energy storage battery, so as to realize the fastest safe charging; meanwhile, when the current is too large, the voltage is too large, and the energy storage level is low, the power management module 700 is used for protecting the storage battery 600.
In one embodiment, the device for detecting the engagement depth of the contact of the circuit breaker further includes an indicator lamp 800, which is disposed on the same side as the digital display meter 500, and electrically connected to the power management module 700, and is used for indicating the electric quantity of the storage battery 600.
