Abstract
The utility model discloses a power supply box overhauls in transformer substation with power cord through wires hole, include that the different with prior art by backplate, two boxes that side board, bottom of the case board, case lid and chamber door are constituteed: be equipped with the power cord through wires hole on the chamber door. The positive power cord through wires hole of chamber door peripheral set up with the spherical protection casing of through wires hole assorted cavity, it is internal to prevent that rainwater etc. From getting into the power supply box. The power cord through wires hole at the chamber door back peripheral set up with through wires hole assorted protective cover, when not using, closed protective cover, it is internal to prevent that insect, toy etc. From getting into power supply boxs. The utility model has the advantages of simple structure, the practicality is strong, and the leakproofness is good, and it is nimble convenient to use.
Description
Technical field
The utility model relates to station power supply box, specifically a kind of station power supply box being provided with power line through wires hole.
Background technology
In the maintenance repair, maintenance work of transformer station, station power supply box often can be used as external power supply feed point.The maintenance power box that current most of transformer station uses is after connecting maintenance power line, power supply chamber door can be clamped power line, power supply chamber door is caused to close, power line also likely crushes by chamber door, power line is caused to break stock time serious, affect the normal use of power line, even may occur the risk causing staff to get an electric shock of leaking electricity; And power supply chamber door can not be closed, as run into sleety weather or toy creeps in maintenance power box, power supply box humidity can be caused to increase, screw corrosion, the problems such as toy damage equipment, all may cause the short circuit of maintenance power box back panel wiring or ground connection, the equipment that affects normally runs, and causes very large hidden danger to the safe operation of transformer station.
More existing novel station power supply boxs, casing is provided with power line through wires hole, but its through wires hole are less, and the band power line of plug and the larger generator power supply line of diameter cannot pass, and utilance is low, uses dumb.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of structure simple, practical, good airproof performance, the flexible and convenient to use station power supply box being provided with power line through wires hole.
The technical scheme realizing the utility model object is:
Be provided with a station power supply box for power line through wires hole, comprise the casing be made up of backboard, two pieces of side boards, box plate, case lid and chamber doors, unlike the prior art: on chamber door, be provided with power line through wires hole.
The diameter of described power line through wires hole is 5-7 centimetre.
The edge of described power line through wires hole is provided with spring protective film, prevent from crushing power line, and at power line through after spring protective film, spring protective film wraps power line, and can gap between self-closed power line and through wires hole, prevent insect, toy etc. from entering in power supply box.
The periphery of the power line through wires hole in chamber door front arranges the spherical protective cover of cavity matched with through wires hole, prevents rainwater etc. from entering in power box.
The periphery of the power line through wires hole at the chamber door back side arranges the protective cover matched with through wires hole, and when not using, closed protective cover, prevents insect, toy etc. from entering in power box.
Use the utility model to be provided with the station power supply box of power line through wires hole, during work, open chamber door, open the protective cover of through wires hole, power line is passed from through wires hole, access power supply, then close chamber door, namely complete the needs of circumscripted power line.Power line through wires hole is provided with spring protective film, protective cover and protective cover, and three's acting in conjunction can effectively prevent toy from entering in power box, and can prevent rainwater from entering in power box.
It is simple that the utility model has structure, practical, good airproof performance, advantage flexible and convenient to use.
