Abstract
The utility model aims to provide an inflatable switch voltage transformer compartment which can be installed in a modular manner and is small in size, low in production cost, and high in reliability. The inflatable switch voltage transformer compartment comprises a cabinet, and a rear side plate, a front side plate, a left side plate, and a right side plate of the cabinet are respectively provided with a rear bending edge, a front bending edge, a left bending edge, and a right bending edge. According to the utility model, the structure of the compartment of inflatable switch equipment is simplified; the modular installation of related devices of the switch equipment is realized; the maintenance is facilitated; and the reliability is high.
Description
Technical field
The utility model relates to the gas-filled type switchgear, specifically a kind of gas-filled type switching voltage instrument transformer compartment.
Background technology
Along with China's electric power and the manufacturing develop rapidly of switchgear, C-GIS gas-filling cabinet, strong adaptability little with its volume, high having obtained of reliability were used in a big way in recent years.The voltage transformer compartment is the important component part of C-GIS gas-filling cabinet, compartment at present commonly used is that voltage transformer is arranged on compartment interior, insulating cylinder must be set so that removable fuse to be installed in charging compartment, the structure of described voltage transformer makes the charging compartment complex structure, volume is large, reliability is low, production cost is high.
The utility model content
The purpose of this utility model is to provide a kind of gas-filled type switching voltage instrument transformer compartment that can modularization is installed, size is little, production cost is low, reliability is high.
The utility model is that to solve the problems of the technologies described above the technical scheme of taking as follows: a kind of gas-filled type switching voltage instrument transformer compartment, comprise casing, be respectively equipped with rear crimp, front crimp, left bending edge, right crimp on the back side panel of described casing, front side board, left plate, right plate.
As further improvement of the utility model, the L-shaped interior bending in back side panel bottom of described casing, described interior bending sidepiece is provided with the voltage transformer socket mounting hole.
Characteristics of the present utility model and beneficial effect: the utility model has been simplified the cell structure of gas-filled type switchgear, has realized that the modularization of switchgear related device is installed, and just with maintenance, volume is little, production cost is low, reliability is high.
Below in conjunction with accompanying drawing, the utility model and effect thereof are described in further details.
