Description

Convenient installation device for high-voltage middle-placed cabinet mutual inductor

Technical Field

The utility model relates to an electric power system mounting tool technical field specifically is a put convenient installation device of cabinet mutual-inductor in high pressure.

Background

At present, along with the high-speed development of social economy, people are increasingly demanding on power consumption, and along with the increase of power consumption load, in order to guarantee the safe and reliable operation of electric power system, the current transformer in the high tension switchgear needs the current transformer that transformation ratio is big, capacity is big, this kind of current transformer's size is big, weight is big, generally needs two operating personnel to operate when installation, change at least, and one of them staff holds up current transformer, and another operating personnel dismouting screw in the switchgear. Because the size of the current transformer is large, an operator for lifting the current transformer also needs to stand in the high-voltage middle-placed cabinet, the operating space in the high-voltage switch cabinet is narrow, the current transformer is very difficult to install or replace, and the operation of the operator for disassembling and assembling screws is very inconvenient and time-consuming; the operating personnel who holds up current transformer need whole journey to lift, must aim at the mounting hole in the cubical switchboard with the mounting hole on the current transformer, because the cubical switchboard space is narrow and small inconvenient to exert oneself and lift whole journey and can not unload the power, has current transformer to drop and injures operating personnel's risk by a crashing object, and operating time is longer the risk is big more.

In order to solve the above problem, the prior art provides a high tension switchgear current transformer installs isolated plant, and patent application number is: 201721129666.2, it includes the automobile body, a side is fixed with the support on automobile body upper portion, the top of support is equipped with intermediate lamella, layer board in proper order, place current transformer on the tray during use, then promote layer board and current transformer to the same high alignment of current transformer mounting hole and cubical switchboard mounting panel mounting hole, operating personnel with the bolt with current transformer fasten the mounting panel on can, this high tension switchgear current transformer installation isolated plant can solve above-mentioned technical problem, but still have following technical problem:

the tray of placing current transformer only can promote from top to bottom, can not the horizontal slip, but among the actual operation process, promote current transformer to current transformer mounting hole and cubical switchboard on behind the same height of mounting hole, still there is the certain distance between the mounting hole on current transformer mounting hole and the cubical switchboard, need operating personnel to promote current transformer toward the direction of being close to the mounting hole on the cubical switchboard, lead to the unsettled still needs operating personnel to hold up current transformer in the same place of current transformer part, lead to whole installation still to have a great deal of inconvenience, the risk that has current transformer to drop and injures operating personnel by a crashing object.

SUMMERY OF THE UTILITY MODEL
