Abstract
The utility model discloses an anti-error type high tension switchgear. A cabinet body is divided into a bus-bar room and a terminal room by a partition plate. A bus and a bus isolating switch are arranged on the upper end of the bus-bar room. The bus-bar room is internally provided with a breaker, and the bottom end of the bus-bar room is provided with a current transformer. The upper end and the lower end of a front surface of the cabinet body are respectively provided with a relay room and a terminal room, and the cabinet body is provided with a breaker operation and interlocking mechanism. The breaker operation and interlocking mechanism is connected with the bus isolating switch and the breaker through connection rods. The back surface of the cabinet body has a shield cabinet which is divided into an outgoing line room and an isolation room by horizontal a partition plate, and the outgoing line room and the isolation room are arranged in a top-and-bottom manner. The outgoing line room is internally provided with an outgoing line room isolating switch, the isolation room is internally provided with a current transformer, and the outgoing line room isolating switch is connected with the breaker operation and interlocking machine through a connection rod. According to the anti-error type high tension switchgear, the isolating switches in the cabinet body and the shield cabinet are connected with the breaker operation and interlocking machine, so that the switching off of a closing circuit is effectively ensured during the operation of the isolating switches.
Description
Technical field
The utility model relates to the high voltage electric power equip ment field, more particularly relates to a kind of anti-error type high-tension switch cabinet.
Background technology
At present, in joining the high-tension switch cabinet of power supply unit, the phenomenon that usually can cause short circuit or personnel to get an electric shock because of misoperation occurs, and makes device damage or casualties.Domestic conventional high-tension switch cubicle, the anti-misoperation of its isolation switch box conjoined vacuum circuit-breaker generally adopts the packaged type procedure lock, but this procedure lock is because but the moving-member people for a change becomes unreliable, also because movable part displacement sometimes, cause using very inconvenient, nearly all high-tension switch cabinet, its anti-misoperation apparatus all can not be accomplished when the beamhouse operation isolating switch, the switch knob before breaker mechanism to be locked, and cuts off the combined floodgate circuit.Therefore be necessary to design the mechanical type incorrect operation preventing interlocking apparatus of high-tension switch cabinet, make the use of interlock in switch cubicle more rationally, accurately.
The utility model content
To achieve these goals, the utility model provides a kind of anti-error type high-tension switch cabinet, by cabinet and blocking in cabinet, isolating switch connecting breaker operation and interlocking machine are installed respectively, by interlocking device, can be effectively guaranteed to have cut off when the disconnecting switch operation combined floodgate circuit.
The utility model specifically is achieved through the following technical solutions:
A kind of anti-error type high-tension switch cabinet, comprise in the cabinet formed by angle steel and Plate Welding, cabinet is divided into bus-bar room and terminal chamber by division board, and described bus and bus isolating switch are arranged on described bus-bar room upper end, described bus indoor location circuit breaker, bottom is provided with current transformer; The positive upper end of described cabinet is provided with relay bungalow, and lower end is provided with the terminal chamber, and cabinet is provided with breaker operator and interlocking device, and described breaker operator and interlocking device connect described bus isolating switch and described circuit breaker by connecting rod; Described cabinet reverse side is connected to one and blocks cabinet, the described cabinet that blocks is divided into upper and lower outlet chamber and isolation ward by the division board of level, the indoor outlet chamber isolating switch that is provided with of described outlet, described isolation ward is provided with current transformer, and described outlet chamber isolating switch connects described breaker operator and interlocking machine by connecting rod.
Described cabinet front and described blocking all are provided with the cabinet door cashier's office in a shop, and described cabinet door is provided with procedure lock.
Described procedure lock connects described breaker operator and interlocking device by described interlock.
The beneficial effect that the utility model produces is: by cabinet, with blocking in cabinet, isolating switch connecting breaker operation and interlocking machine are installed respectively, can effectively guarantee to have cut off when the disconnecting switch operation combined floodgate circuit by interlocking device, very safe and reliable, and simple in structure easy to operate.
