Abstract
The utility model belongs to a safety protecting device for high voltage electrical apparatus. The utility model is mainly used for the interlocking protection for a high voltage vacuum breaker and a high voltage isolating switch. The device effectively prevents a high voltage interphase short circuit accident caused by faulty operation. The utility model is characterized in that an extending shaft is installed on a main shaft of the high voltage vacuum breaker, the extending shaft is connected with a movable turning arm, a connecting rod and a fan-shaped plate, a contact block is arranged on the fan-shaped plate, and the fan-shaped plate acts along with the on-off of the breaker. The contact block contacts or is separated from a corresponding elastic contacting point; when the contact block contacts the corresponding elastic contacting point, a positioning pin of the high voltage isolating switch is blocked and can not be drawn, and a switch handle can not be operated; vice versa, the switch can act. Therefore, the utility model realizes mechanical interlocking.

Accompanying drawing 3 is A of the present utility model portion enlarged drawings.
The utility model is achieved in that by derivation mechanism, linkage, meets and discusses etc. The high-tension vacuum circuit breaker mechanical interlock protector that forms is characterized in that arranging and draws Axle 4 is connected with high-pressure vacuum breaker main shaft 3, adopts inner bolt to connect with one heart, is drawing axle 4 end faces arrange alignment pin 17, with the pin-and-hole tight fit on the main shaft 3. Solid at high-tension switch cabinet Decide to establish on the frame 18 bearing bracket 13, bearing block 5 parallel being contained on the bearing bracket 13, Draw axle 4 by the axis hole on the bearing block 5, draw axle 4 and be orthogonal with bearing bracket 13, Making to draw between axle 4 and the main shaft 3 does not have relative displacement, guarantees the concentricity of diaxon. Drawing End connects an adjustable connecting lever 6, and connecting lever 6 is provided with one group of adjusting hole 21 along brachium. Connected by connecting lever 6 Connect a scalable regulating connecting rod 7, all be provided with bolt at connecting rod 7 two ends and regulate connecting rod 7 one Termination connecting lever 6, the other end connect a fanning strip 8, and the central angle end of fanning strip 8 is connected height On the interlock bracket 9 of cabinet panel 16 inboards of compressing switch; Fanning strip 8 along camber line be provided with one group with Connecting rod 7 connects the adjusting hole 20 of usefulness; The radius of fanning strip 8 is provided with a contact block 19, The contact-making surface of contact block 19 and elastic buffer head 10 tails that are arranged on the high-tension switch cabinet plate face 16 Section is corresponding, forms a butt contact. The installation position of elastic buffer head 10 should make high pressure every Leave alignment pin 14, the contact block on the fanning strip 8 19 and the elastic buffer head of pass at same axle On the line. Exit of drawing axle 4 of the present utility model and connecting lever 6, connecting lever 6 and connecting rod 7, Connecting rod 7 and fanning strip 8, fanning strip 8 are rotating with being connected of interlocking mechanism support 9 Be flexibly connected.
The utility model has mechanically been controlled the operating sequence of high-pressure vacuum breaker and high voltage isolator, the alignment pin of high voltage isolator must just can be pulled up when high-pressure vacuum breaker place what gate-dividing state, effectively stop the operation of high voltage isolator on-load, avoided the accidents such as high pressure phase fault that cause because of misoperation.
The utility model is simple in structure, installation is easy to adjust, is applicable to various types of high-pressure vacuum breakers and high voltage isolator assembly.Reliable in action, can effectively avoid the accidents such as high pressure phase fault that cause because of misoperation, ensure safety in production.
The utility model is work like this: when high-pressure vacuum breaker place what "on" position, drawing axle 4 moves simultaneously with main shaft 3, connecting lever 6 is stretched, drivening rod 7, fanning strip 8 rotates, contact block 19 on the fanning strip 8 withstands the elasticity afterbody of meeting and discussing, elasticity is met and discussed and 10 is stretched out, block high voltage isolator alignment pin 14, it can not be extracted, the high voltage isolator handle can not be operated, otherwise, after high-pressure vacuum breaker is operated a switch, draw axle 4 drive connecting levers 6 and hang down, connecting rod 7 makes fanning strip 8 rotate an angle, elasticity is met and discussed and 10 is resetted, high voltage isolator alignment pin 14 exposes, extract alignment pin, operating grip, isolating switch separating brake.
