Description

A kind of moveable high-voltage switchgear with bypass
Technical field
The utility model belongs to appliance field, is specifically related to switch cubicle.
Background technology
The existing medium and small generator that is used for the power plant send electricity, industrial and mineral enterprises and institutions distribution, electric power system secondary to be subjected to electricity or send the high-tension switch cabinet of the startup of electricity and large-scale high-tension motor, mostly belong to single busbar system and comprise casing, the bus-bar room that isolates in the casing, circuit breaker cart chamber, cable vault, relay control room.At bus-bar room main bus bar, branch bar, circuit breaker fixed contact, current transformer are installed.Circuit breaker cart is installed in the handcart chamber.Cable, earthed switch, earth bus, lightning arrester etc. are installed by the cable vault.Though aforesaid switch cubicle can satisfy the power supply instructions for use of electric power system, but switchgear is when breaking down and overhaul, need stop power supply to power consumption equipment, this to some power supply reliability height, need the place of uninterrupted power supply when switching devices is overhauled, as hospital, airport, station, oil field etc., can cause the long period to have a power failure.
Summary of the invention
The purpose of this utility model provides a kind of moveable high-voltage switchgear with bypass, overcomes existing switch cubicle above shortcomings.
Switch cubicle of the present utility model by the bypass cabinet with feed out group and become, bypass cabinet wherein comprises bus-bar room, circuit breaker cart chamber, relay control room, bypass chamber, bus-bar room is installed main bus bar, branch bar, circuit breaker fixed contact, current transformer, the bus summation current transformer connects the circuit breaker fixed contact respectively, the circuit breaker cart of moving contact of breaker through being installed in the handcart chamber connects, and the current transformer other end connects the hospital bus bar that is installed in bypass chamber through isolating switch; Feed out cabinet and comprise bus-bar room, circuit breaker cart chamber, relay control room, current transformer chamber, cable vault, bypass chamber.Bus-bar room is installed main bus bar, branch bar, circuit breaker fixed contact, instrument transformer is installed in the current transformer chamber, the bus summation current transformer connects the circuit breaker fixed contact respectively, the circuit breaker cart of moving contact of breaker through being installed in the handcart chamber connects, the current transformer other end is mounted on the feed-out cable and the isolating switch that is installed in bypass chamber of cable vault through isolating switch, isolating switch connects hospital bus bar again.
Use of the present utility model is, feeds out cabinet when normally moving, and isolating switch, the feed-out cable of electric current between circuit breaker, circuit breaker output and the feed-out cable of main bus bar, connection transported to the user.The bypass cabinet breaker, hospital bus bar does not have.State path cashier's office in a shop and break down and need maintenance when certain feeds out, cutting off has fault to feed out circuit breaker and isolating switch, isolating switch and the ground connection of cabinet.Closure feeds out the by-pass switch in the cabinet, connects hospital bus bar and feed-out cable.Connect bypass cabinet breaker and isolating switch, make hospital bus bar charged and, continue power supply to electricity consumption department through bypass isolating switch guiding feed-out cable
Use good effect of the present utility model to be: the switchgear (containing current transformer) that feeds out cabinet at day-to-day operation breaks down and when overhauling, switch in the closed bypass cabinet, connect main bus bar and hospital bus bar, the closed again bypass isolating switch that feeds out in the cabinet, keep feeding out the uninterrupted power supply of cabinet, eliminate the infringement of bringing for power consumption equipment and electricity consumption department because of the fault of switch cubicle.
