Abstract
The utility model discloses a kind of high voltage power distributing cabinet changing current transformer position, comprise bus-bar room, breaker chamber, cable vault and upper partition, described bus-bar room is positioned at the top of high voltage power distributing cabinet, breaker chamber is positioned at the side of bus-bar room and itself and bus-bar room is separated by upper partition, cable vault is positioned at the below of bus-bar room, busbar is comprised in described bus-bar room, electrified sensor I and contact box I, circuit breaker is positioned at the inside of breaker chamber, described cable vault comprises current transformer, copper bar, contact box II, electrified sensor II, cable, lightning arrester and zero sequence current sensor.This power distribution cabinet can according to the height of bus size determination bus-bar room, make the setting height(from bottom) of current transformer is carried, to the space that cable vault is maximum, and then the electric clearance of current transformer and cable is increased, the space trend rationalization more of the components and parts of device interior, the security performance of integral device improves, and the heat dispersion of components and parts also gets a promotion.
Description
Technical field
The utility model belongs to field of electrical equipment, is specifically related to a kind of high voltage power distributing cabinet changing current transformer position.
Background technology
High voltage power distributing cabinet is a kind of switchgear assembly and control appliance, and it is as power center (PC) and main switching compound, main as the control to power circuit, primary electricity using device, supervision, measuring and protection, sets up and is placed in transformer station, switchgear house.And the electric clearance in high voltage power distributing cabinet can have influence on the product quality of high-tension apparatus, electric clearance is large is conducive to the stability of product quality, and equipment maintenance is after operation convenient with maintenance, and internal electric gap is less, be then unfavorable for that components and parts dispel the heat.Present stage, the interior layout of each high voltage power distributing cabinet was scarcely the same, the position of current transformer often in the place near below, such mode make current transformer installation or later maintenance all inconvenient, be more unfavorable for the heat radiation of components and parts in cabinet.
Utility model content
For problems of the prior art, the utility model provides a kind of high voltage power distributing cabinet changing current transformer position, solves existing equipment and to dispel the heat because cable is more bad problem.
In order to solve the problems of the technologies described above, the utility model realizes in the following manner:
A kind of high voltage power distributing cabinet changing current transformer position, comprise bus-bar room, breaker chamber, cable vault and upper partition, described bus-bar room is positioned at the top of high voltage power distributing cabinet, breaker chamber is positioned at the side of bus-bar room and itself and bus-bar room is separated by upper partition, cable vault is positioned at the below of bus-bar room, busbar is comprised in described bus-bar room, electrified sensor I and contact box I, circuit breaker is positioned at the inside of breaker chamber, described cable vault comprises current transformer, copper bar, contact box II, electrified sensor II, cable, lightning arrester and zero sequence current sensor, described current transformer is arranged at the top of cable vault, the side of cable instrument transformer is fixed by contact box II and breaker chamber, below it, copper bar is installed, described copper bar is connected with lightning arrester after mid portion is fixing by electrified sensor II again, the upper end of described cable is connected on copper bar, lower end is connected with zero sequence current mutual inductor.
Further, described high voltage power distributing cabinet also comprises pressure relief device, and described pressure relief device is arranged at the top of bus-bar room and breaker chamber.
Compared with prior art, the beneficial effect that the utility model has: according to the height of bus size determination bus-bar room, make the setting height(from bottom) of current transformer is carried, to the space that cable vault is maximum, and then the electric clearance of current transformer and cable is increased, the space trend rationalization more of the components and parts of device interior, the security performance of integral device improves, and the heat dispersion of components and parts also gets a promotion.
