Abstract
An air-insulated metal-sealing switch equipment with a single air chamber comprises a cable chamber, a low-pressure chamber and a primary major loop circuit which is connected with the cable plug in the cable chamber, wherein the air-insulated metal-sealing switch equipment with a single air chamber is provided with an air charging case with pressure release passage which are connected with the cable chamber and the low-pressure chamber respectively, the high-voltage conductive component of the primary major loop circuit is arranged in the air charging case which is provided with a master switch consisting of a vacuum breaker and a three-working position isolation grounding switch. The utility model is a single air chamber design, which has advantages of avoiding gas leakage between air chambers in double air- chamber structure, facilitating installation for electrical components in the major loop, ensuring high accuracy of connection and high reliability of overall design, simplifying structure and ecomomizing production cost; at the same time, the three-working position isolation grounding switch coordinates with the vacuum breaker, thereby facilitating interlocking between the three-working position isolation grounding switch and the vacuum breaker and simplifying operation.
Description
Technical field
The utility model relates to a kind of switchgear of high-tension circuit, is a kind of single air chamber gas-insulated metal enclosed switch equipment specifically.
Background technology
Development along with domestic and international electric utility, particularly in 12KV～40.5KV three-phase ac power system, gas-insulated metal enclosed switch equipment commonly used mostly is two air chambers arrangement up and down, main bus bar with in branch bus places different air chambers respectively, avoided influencing each other when producing fault, made faulty component obtain partial division.And the gas-insulated metal enclosed switch equipment arranged up and down of the two air chambers of this employing, how arranged apart isolating switch and circuit breaker, isolating switch is located in the main bus bar air chamber, circuit breaker then places in the branch bus air chamber, but, adopt the gas-insulated metal enclosed switch equipment of this structure, realize that the mechanical chain difficulty between its isolating switch and the circuit breaker is bigger, in Installation and Debugging and real work, reliability is relatively poor.Simultaneously, the switchgear mechanical devices of two air chamber structures is more, and manufacture difficulty is bigger, and the gas between two air chambers leaks easily, makes the sealing property of whole switchgear be difficult to more guarantee, in addition, connection required precision height between two air chambers, install complicated, the manufacturing cost height.
Summary of the invention
The purpose of this utility model provides a kind of reliability height, and is simple in structure, single air chamber gas-insulated metal enclosed switch equipment of low cost of manufacture.
Goal of the invention of the present utility model is achieved in that a kind of single air chamber gas-insulated metal enclosed switch equipment, comprises cable vault, low-pressure chamber and a main loop circuit, and main loop circuit is electrically connected with cable joint in the cable vault.It is characterized in that: be provided with the inflation casing of band pressure relief channels in described single air chamber gas-insulated metal enclosed switch equipment, the inflation casing is connected with low-pressure chamber with the cable vault respectively, is provided with the high pressure conducting element of a main loop circuit in the inflation casing.
Be provided with main switch in the described inflation casing.
Described main switch is a vacuum circuit-breaker.
Described main switch is three station isolation earthing switch.
Described main switch is connected to form by vacuum circuit-breaker and three station isolation earthing switch.
The utility model improves existing gas-insulated metal enclosed switch equipment, switchgear is single air chamber setting, the high pressure conducting element of major loop and main switch are placed in the inflation casing, avoided causing gas leakage phenomenon between two air chambers because of welding and quiet connection, and each electric component in the major loop is easy for installation, the connection precision height of electric component makes integral body have the reliability height, the advantage of simple in structure, low cost of manufacture; Simultaneously, three station isolation earthing switch and vacuum circuit-breaker cooperating are realized the convenient interlocking between three station isolation earthing switch and the vacuum circuit-breaker easily, and be simple to operate; And each part is modularization, the easier needs that satisfy various Main Wire Connection Scheme, applied range.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, the utility model list air chamber gas-insulated metal enclosed switch equipment comprises cable vault 1, low-pressure chamber 2 and a main loop circuit.For fear of causing gas leakage phenomenon between two air chambers because of welding and quiet connection, be provided with independent inflation casing 3 in this switchgear, inflation casing 3 is fixedlyed connected with cable vault 1, low-pressure chamber 2 respectively, and 4 concentrated being located in the inflation casing 3 of the high pressure conducting element in main switch and the major loop, each electric component connects the precision height, easy for installation, integral device is simple in structure, the reliability height.And main switch can be vacuum circuit-breaker 5, also can be three station isolation earthing switch 6, or connect to form by vacuum circuit-breaker 5 and three station isolation earthing switch 6, in the present embodiment, main switch is the latter, easier between the two realization mechanical interlocking each other, and both running parts adopt special bellows movable sealing structure, sealing reliability height has not only improved simultaneously both mechanical endurance greatly.Have pressure relief channels in the inflation casing 3, its pressure relief channels is mainly used to discharge the fault pressure of aeration tank 3 inside.And inflation casing 3 is the single air chamber mechanism that the stainless steel plate is welded, and makes to inflate casing 3 and have little, the lightweight advantage of volume, improves the air-tightness of integral device again.It is assembled that 1 of cable vault makes part by the aluminizing zine plate, and built-in cable joint is electrically connected with the high pressure conducting element 4 of main loop circuit in the inflation casing 3.Other switch auxiliary element then is housed in the low-pressure chamber 2.Each part of the present utility model is modularized design, and the easier needs that satisfy various Main Wire Connection Scheme make to the utlity model has the reliability height, and are simple in structure, in the time of the characteristics of low cost of manufacture, also has widely used advantage.
