Abstract
The utility model provides a voltage transformer with a water-proof anti-condensation terminal box, and the voltage transformer comprises the terminal box; a through hole is arranged in the terminal box; a ventilation mesh is arranged on the through hole; and a baffle cover is arranged around the through hole. According to the voltage transformer with the water-proof anti-condensation terminal box, because the hole is arranged in the bottom wall of the terminal box and the copper ventilation mesh is arranged on the hole, the terminal box is communicated with the outside environment, the temperature is not too high and condensation is prevented; and because the baffle cover is covered on the copper mesh, three sides of the baffle cover are welded and sealed and a gap is left on one side surface of the baffle cover, the terminal box and the outside environment are communicated through the copper mesh, dust and rainwater do not enter the terminal box, simultaneously little condensation in the terminal box flows out through the copper mesh, so that a line fault caused by secondary side short circuit is prevented. According to the voltage transformer with the water-proof anti-condensation terminal box, the structure is reasonable, water and condensation can be effectively prevented, and the operation is stable and reliable.
Description
Technical field:
The utility model relates to a kind of voltage transformer.
Background technology:
Present stage, domestic electricity needs was increasing; The demand of corresponding power transmission and transforming equipment is also increasing; Electric power system constantly promotes the degree of recognition of GIS; The continuous increase of As GIS market consumption, the market demand of voltage transformer is also increasing, is necessary to provide a kind of GIS of dependable performance to satisfy the demand in market with voltage transformer.The terminal box of existing voltage transformer is an airtight space, and at work, the temperature of terminal box can be high more a lot of than extraneous, form condensation easily, and is so long-term, will form ponding in the terminal box, thereby cause secondary circuit short-circuit, causes line fault.
The utility model content:
The purpose of the utility model is to provide the voltage transformer of the anti-condensation of a kind of terminal box waterproof, and it is rational in infrastructure, stable and reliable operation.
In order to achieve the above object, the utility model adopts following technical scheme:
The voltage transformer of the anti-condensation of a kind of terminal box waterproof comprises terminal box, offers a through hole on the said terminal box, on the said through hole gas-permeable nets is installed.
Said gas-permeable nets is the copper gas-permeable nets.
Said through hole is arranged at terminal box on the wall of the earth one side.
Be provided with the baffle plate cover around the through hole.
One sidewall and the atmosphere of baffle plate cover.
Said voltage transformer also comprises a body; Terminal box is arranged on the body.
With respect to prior art, the utlity model has following advantage: the utility model, install the copper gas-permeable nets additional through perforate on the terminal box diapire, make terminal box communicate with the external world, temperature can be too not high, prevents to form condensation; On copper mesh, cover a baffle plate cover again; Three face down bondings connect sealing; The space is left in one side, makes terminal box communicate through copper mesh with extraneous, promptly prevents dust and the rainwater into terminal box that wafts; A small amount of condensation in the terminal box is flowed out through copper mesh, prevent secondary circuit short-circuit and cause line fault.The utility model voltage transformer is rational in infrastructure, and effectively waterproof is prevented condensation, stable and reliable operation.
Description of drawings:
Fig. 1 is the outline drawing of the voltage transformer of the anti-condensation of a kind of terminal box waterproof of the utility model;
Fig. 2 is the upward view of Fig. 1.
Wherein: 1---the baffle plate cover, 2---the copper gas-permeable nets, 3---the secondary wire hole.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
See also Fig. 1 and shown in Figure 2, the voltage transformer 100 of the anti-condensation of a kind of terminal box waterproof of the utility model mainly comprises: the body 10 and terminal box 20.Voltage transformer 100 docks with GIS200 through disc insulator.
The body 10 is weldments, is made up of lower flange, time cylinder, end socket, last cylinder, upper flange and hanger; Terminal box 20 by patchboard, guide rail, connecting terminal block and have the door box form.The secondary side of voltage transformer 100 is forbidden short circuit, so terminal box 20 requires waterproof to prevent condensation, in order to avoid ponding causes secondary circuit short-circuit in the case.On the following lateral box wall of terminal box 20, open an aperture installs a copper gas-permeable nets 2 and a baffle plate cover 1 additional to the utility model voltage transformer 100 exactly, to reach the anti-condensation of terminal box waterproof, prevents the purpose of secondary circuit short-circuit.The terminal box 20 of voltage transformer 100 is airtight spaces, and at work, the temperature of terminal box 20 can be high more a lot of than extraneous, form condensation easily, and is so long-term, will form ponding in the terminal box 20, thereby cause secondary circuit short-circuit, causes line fault; Copper gas-permeable nets 2 is installed in perforate additional on the box wall, is in order to make terminal box 20 communicate with the external world, and temperature can be too not high, prevents to form condensation; On copper gas-permeable nets 2, cover a baffle plate cover 1 again; Three face down bondings connect sealing, and the space is left in a side, make terminal box 20 communicate through copper gas-permeable nets 2 with extraneous; The effect of baffle plate cover 1 is to prevent dust and the rainwater into terminal box that wafts, and promptly is the protective cover of copper gas-permeable nets 2.Must guarantee that wherein copper gas-permeable nets 2 and baffle plate cover 1 are installed on a lateral box wall of the earth, prevent that the rainwater dust from directly pouring into terminal box 20, a small amount of condensation in the terminal box is flowed out through copper mesh, prevent secondary circuit short-circuit and cause line fault.Also be provided with secondary wire hole 3 on the terminal box 20.
