Abstract
The utility model relates to fully-insulated looped-network type high-voltage switching equipment. The fully-insulated looped-network type high-voltage switching equipment comprises a shell, a high-performance breaker module which is sealed in a sulfur hexafluoride (SF6) gas tank, a fully-sealed power module which is arranged in the shell, bus channels which are isolated from one another, and wire side-outgoing and expansion modes, wherein the high-performance breaker module consists of a reliable depressurizing channel; and cabinets are connected through insulating buses. The fully-insulated looped-network type high-voltage switching equipment has the advantages that: the cabinets are connected through the insulating buses, a cable outgoing end can realize the wire side-outgoing and expansion modes as required, and a current transformer can be pre-arranged; the high-voltage switching equipment is safe and convenient, simple in structure, and convenient to operate; accident propagation under failure is effectively prevented; and personal safety and property safety are ensured, and the using performance of the high-voltage switching equipment is improved.
Description
Technical field
The utility model is specifically related to manufacturing enterprise and the power supply management distribution is used the high pressure ring switchgear, is specifically related to a kind of all insulation looped network formula high voltage switchgear.
Background technology
Present manufacturing enterprise and power supply management all need use a large amount of high voltage switchgears, are used for industry and civilian cable ring-system and power supply end.Again because its complex structure is bulky, capital construction required high when existing high voltage switchgear cost was high, put unreasonable, can be because of in disorder line short, causing can not normal power supply, property loss is serious.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of simple in structure, easy to operate and all insulation looped network formula high voltage switchgear that security performance is good.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of all insulation looped network formula high voltage switchgear comprises shell, is sealed in the high-performance breaker module in the SF6 gas tank; Be installed on the all-sealed power module in the shell; And the busbar channel and the side outlet extended mode of isolating each other; It is characterized in that; The formation that comprises shell, high-performance breaker module; The formation of combined electrical apparatus backup protection is installed on shell internal upper part busbar channel and side outlet extended mode, is installed on the all-sealed power module in the shell, the current transformer that can pre-install, and the cable outlet end that the ground on the diapire is arranged and is installed on bottom in the shell in the shell is installed.
Preferably, said all insulation looped network formula high-voltage switch gear, it is the high-performance breaker module that is sealed in the SF6 gas tank.
A kind of all insulation looped network formula high voltage switchgear that the utility model is set forth; Compared with prior art; Its beneficial effect is: the utility model in the power distribution cabinet shell institute once live part be sealed in the SF6 gas tank; Bus is connected with mutual isolate bus passage, prevents spreading of accident under the failure condition effectively; Downside can be installed all insulation power module or current transformer as requested in advance, and the lead-out wire of cable outlet end can be according to the requirement of client flexible configuration; Need not to install additional moistureproof heater, reduced line loss effectively; Pressure release passage is at the equipment back, also improved the serviceability of joining high voltage switchgear when having guaranteed the safety of the person, property, and is simple in structure, easy to operate.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of all-insulated switch equipment of the utility model;
Accompanying drawing 2 connects and side outlet extended mode sketch map for the downside cable.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, all insulation looped network formula high voltage switchgear of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
Shown in Fig. 1 ~ 2, a kind of all insulation looped network formula high voltage switchgear comprises high performance switch module 13, bus tie 11, cable connector 14, ground connection copper bar 15, pressure release passage 17.Be connected in high-performance module 13 through cable connector 14; Shell upper has the bus-bar room of mutual isolation, is connected in other modules or cable side outlet method through bus tie 11, and outer casing underpart has cable joining room; Ground connection copper bar 15, and through cable connector 14 connection outlet cables.The full-insulating high-voltage switch adopts modularized design, and its elementary cell is on-load switch module, combined electrical apparatus module, breaker module and other special functional modules.The integrated three-station 12 of on-load switch and earthed switch, simple in structure, flexible operation, interlocking are reliable, and reliable pressure release passage 17 is arranged; The combined electrical apparatus backup protection is equivalent to overload protection to a certain extent, has remedied the deficiency of the only short-circuit protection of fuse; The high-performance breaker module still can be at disjunction 20KA electric current under the short-circuit conditions when air gauge is zero, and the short circuit making current reaches 60KA.All modules can realize outlet under the cable according to customer requirements, side outlet and extended mode.Power module can be installed in cable vault, switch lower end or bus bar side, still keeps full-insulated full-sealed characteristics, solves user's operating power and voltage signal acquisition problem comprehensively.It is logical that bus is connected with mutual isolate bus, adopts isolated bus to be connected safe ready between cabinet and cabinet.This novel full-insulating high-voltage switchgear is applicable under the various environment such as humidity, many dirt, salt dirt, mine, high height above sea level and uses that electric property has reached the maintenance-free performance (30 years) of IEC standard.
The above person of thought; Be merely the preferred embodiment of the utility model; When the scope that can not limit the utility model enforcement with this; The content of promptly being put down in writing according to the utility model claim and utility model specification has generally been done simple equivalent and has been changed and modification, all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the interest field that is used for limiting the utility model.
