Abstract
Disclosed is a source chamber for transformer substation maintenance, comprising a box body and a box door, wherein the box door is installed upon the box body; the box body is internally provided with a circuit board; each branch circuit is electrically connected with a leakage protector; and the leakage protector is installed inside the box body. The source chamber of the utility model features reasonable design, simple structure, high practicality, and secure usage. The employment of this source chamber can meet the regulation that the branch circuit switch of the source chamber for maintenance shall be equipped with residual current motion protector (leakage protector) listed in Power System Safety Work Regulations (power transformation section) by the State Grid Corporation of China. Moreover, after the wiring operation, the source chamber door can be normally closed and the cables can be fixed in order.
Description
Technical field
The utility model relates to transformer station in power domain from the electricity consumption part, especially a kind of station power supply box.
Background technology
At present, station power supply box standard disunity, usually there are two major defects in existing maintenance power box: 1, the part maintenance power box does not satisfy in State Grid Corporation of China's " electric power safety working regulation (power transformation part) " about the regulation of " branch switch of maintenance electrical source of power case all should install RCD (earth leakage protective device) additional ", has potential safety hazard; 2, mostly in the direct wiring of air circuit end opening, wiring is dangerous in wiring, and after wiring, the maintenance power box door can't be closed, and wiring easily comes off.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can reduce potential safety hazard and ensure firmly station power supply box of wiring.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of station power supply box comprises casing and chamber door, and chamber door is arranged on casing, mounting circuit boards in casing, and it is characterized in that: every branch road all is electrically connected to earth leakage protective device, and this earth leakage protective device is arranged in casing.
And the end of described every branch road all is electrically connected to binding post or socket, and this binding post or socket are installed on the interior bracing frame of casing.
And an entrance hole is all made in the bottom of described casing left side wall and right side wall, and a fixture all is installed on the cabinet wall of each entrance hole side.
And described fixture is the U-shaped hook of a horizontal positioned, and one of them straight-arm of this hook is arranged on the box inside wall.
And the outer wall of described casing is installed the end cap that is used for hiding entrance hole.
Advantage of the present utility model and beneficial effect are:
1, on every of this maintenance power box branch road, earth leakage protective device is installed all, has been met security regulations, reduced potential safety hazard, extended useful life of power equipment.
2, the end of every of this maintenance power box branch road is installed binding post or socket, so wiring is safe and reliable, difficult drop-off.
3, this maintenance power box lower sidewall is made the inlet wire circular hole, not only facilitates wiring, and after wiring, chamber door can normally be closed.
4, fixing device for installing on the cabinet wall of this maintenance power box, this fixture can play fixed cable and avoid the effect that comes off.In addition, after using fixture, can also guarantee the neat standard of casing internal wiring.
5, the end cap installed of this maintenance power box cabinet exterior can play and hide entrance hole, prevent that dust or rainwater etc. from entering casing, keeping the effects such as box shape is attractive in appearance.
6, the utility model is a kind of reasonable in design, simple in structure, practical, station power supply box of using safety; use this power supply box not only can satisfy in State Grid Corporation of China's " electric power safety working regulation (power transformation part) " regulation about " branch switch of maintenance electrical source of power case all should install RCD (earth leakage protective device) additional "; and after wiring, the maintenance power box door can normally be closed, and cable can neatly be fixed.
