Abstract

The utility model discloses a circuit breaker cabinet with a disconnecting switch. The circuit breaker cabinet comprises a cabinet body (4) provided with a control mechanism chamber (1), a cable chamber (6) and a pressure release chamber (7), a gas tank (8) is mounted on the cabinet body (4), a circuit breaker (9) is installed on the gas tank (8), a circuit breaker control mechanism (3) connected with the circuit breaker (9) is arranged in the control mechanism chamber (1), the disconnecting switch (13) is arranged between a bus connection seat (17) and the circuit breaker (9) in the gas tank (8), and a disconnecting switch control mechanism (2) connected with the disconnecting switch (13) is arranged in the control mechanism chamber (1). The circuit breaker cabinet solves the problem of assembling different function modules on the same standard gas tank. All high pressure parts are sealed in the gas tank, the space arrangement is reasonable, and the problem of difficult assembly is solved.

Description

The breaker cabinet of band isolating switch
Technical field
The utility model relates to high voltage electric equipment manufacturing technology field, and particularly a kind of circuit breaker is contained in the breaker cabinet in the sulphur hexafluoride insulation gas tank.
Background technology
Current, in the sulfur hexafluoride gas-insulating ring main unit in the 12kV/24kV distribution system, breaker cabinet generally is not with isolating switch, and the main bus bar of breaker cabinet is not to seal fully, increase isolating switch as needs and then need to widen or increase whole cabinet, cause the versatility of unit not good, production cost is higher.It is not good that the utility model will solve this type of versatility exactly, not with the circuit breaker ring main unit situation of isolating switch, the circuit breaker and the isolating switch of standard module function all is assemblied in the gas tank operating mechanism mutually noninterfere simultaneously.
Summary of the invention
Problem to be solved in the utility model provides a kind of breaker cabinet with tri-station isolating switch, installs the problem that isolating switch causes manufacturing cost height and assembling difficulty additional to solve existing circuit breaker ring main unit.
To achieve these goals, the technical solution of the utility model is: the breaker cabinet of this band isolating switch, comprise the cabinet that is provided with operating mechanism chamber, cable vault and pressure releasing chamber, be contained in the gas tank on the cabinet, be contained in the circuit breaker in the described gas tank, at the indoor breaker operation mechanism that connects described circuit breaker that is equipped with of described operating mechanism, in described gas tank, between mother block and described circuit breaker isolating switch is housed, it is indoor that the isolating switch operating mechanism that is connected with described isolating switch is contained in described operating mechanism.
In the technique scheme, described isolating switch connects in the inside of gas tank by being connected copper bar with described circuit breaker; The isolating switch operating mechanism of described isolating switch and the breaker operation mechanism of described circuit breaker are separate; The three-phase outlet sleeve pipe level that described circuit breaker output connects is arranged in the bottom of gas tank front panel.
In the technique scheme, described circuit breaker is that epoxy resin is as the circuit breaker insulation crust with the manufacturing of epoxy resin die casting vacuum interrupter, and vacuum interrupter is as the critical component of the connection and the disjunction of high-tension current.The circuit breaker bottom connects copper bar and directly is connected with the outlet sleeve pipe, and is simple and reliable, easy to assembly.
Adopted such scheme by ground, the utility model compared with prior art has following beneficial effect:
1, tri-station isolating switch is made of three-stations load switch cancellation arc-control device, and its operating mechanism is exactly the operating mechanism of original on-load switch simultaneously, can avoid design iterations and checking again, continues original design;
2, three-phase breaker is designed in gas tank, the copper bar that is connected with circuit breaker all is installed in the gas tank, and the epoxy resin pressure injection of breaker vacuum arc control device simultaneously can increase the insulating properties of high-pressure section;
3, being connected of circuit breaker and isolating switch, isolating switch is connected with horizontal main bus bar, and circuit breaker all uses copper bar with being connected of outlet sleeve pipe, produces simply, easy to assembly, reduces breaker cabinet production difficulty.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail;
Accompanying drawing 1 is the left surface broken away view of the utility model embodiment;
