Description

Modularization withdraw-type solid-state insulated switchgear
Technical field
The present invention relates to a kind of indoor mid-handcart withdrawing switch apparatus, particularly a kind of 12~24Kv that is applicable to, the middle-size and small-size modularization withdraw-type of 50Hz three-phase alternating current electrical network solid-state insulated switchgear.It mainly is applicable to urban architecture, market, public utilities, airport, railway, traffic, coal, chemical industry, iron and steel, industrial and mining enterprises and power transmission and transformation station and power plant etc.
Background technology
At present, the switchgear of prior art can be divided into by structure: fixed switch arrangement and withdrawing switch apparatus; Can be divided into by dielectric: air, inflation and compound inslation.Air-insulated switchgear once each electric elements and galvanic circle leaks cruelly in air, and volume is large and anti-environment is poor, is applicable to general running environment.Each electric elements of gas-filling cabinet and galvanic circle are enclosed in the SF6 gas, and volume is little, and insulation level is high, and anti-environment is good, is applicable to higher operational site.Such as track traffic, skyscraper etc.Gas-filling cabinet mostly is fixed and is difficult to be designed to withdraw-type switch cabinet, and power supply continuity is aobvious not as withdraw-type switch cabinet.SF6 gas is one of " Kyodo Protocol " clear and definite gas.Very big to environmental impact, should limit use.Along with the development of electricity market and the progress of high-voltage switch gear technology, bulky air-insulated floatless switch equipment such as GG-1A are replaced by the XGN2 of small volume and the less SF6 gas-filling cabinet of volume.In order to solve the continuity of power supply, fixed switch arrangement is landed again withdraw-type equipment such as KYN1 and JYN2 and is replaced; In order to solve interchangeability and miniaturization issues, replaced by the compound inslation middle disposed withdrawn type switchgear of at present popular output maximum again take the withdrawing switch apparatus that lands of air by dielectric.Its representative products such as KYN28 etc.For energy-conservation, reduce equipment volume, make the product miniaturization, at present the SF6 inflation regime etc. that adopt more.
Summary of the invention
The purpose of this invention is to provide a kind of modularization withdraw-type solid-state insulated switchgear, solved that the volume that existing switchgear exists is large, power supply continuity is poor and the problem such as SF6 contaminated environment, its compact conformation, reasonable in design, parts are realized modularization, dielectric strength is high, and interchangeability is good, is convenient to on-the-spot installation, debugging, safe and reliable, reach at the scene the purpose that makes up, leans on wall installation, cabinet to overhaul previously, can exempt from especially to be influenced by the adverse circumstances, increase the service life.
The technical solution adopted in the present invention is: this modularization withdraw-type solid-state insulated switchgear comprises cabinet and is assembled in respectively the interior power house module of cabinet, bus-bar room module and cable vault's module, it is characterized in that: described power house modular tank, the charged primary conductive element of in bus-bar room modular tank and the cable vault's modular tank all, bus, adopt solid dielectric insulation to coat respectively and be packaged into the cabinet module, by the power house module by keeper and cable vault's module, the bus-bar room module is connected to form monolithic construction, mutually seals isolation by metal partion (metp) between each module; The power house module is positioned at the top of cabinet front portion, and the bus-bar room module is positioned at top, cabinet rear portion, and cable vault's module is positioned at the cabinet bottom, and each Modular surface is coated with conduction or semiconductive shielding layer, and direct reliable ground.
Described power house module is mainly by three individual compartment, namely little bus-bar room, control room, breaker chamber and a power house pressure release passage, and control room's protection channel consists of; Be assembled with guide rail interlocking unit, solid insulation middle disposed withdrawn type breaker unit, shutter unit and secondary interlocking unit in the breaker chamber.
Described bus-bar room module is mainly by bus-bar room pressure release passage, solid insulated busbar adapter unit and solid insulating sleeve cell formation.
Described cable vault module mainly is made of cold air interchange channel, solid insulation earthed switch unit, solid insulation cable terminal unit, solid insulation mutual inductor unit, solid insulation disjunctor contact box unit, front door interlock unit, overvoltage protection device and cable end.
Carry out Optional assembling by the power house module of the described cable vault module of combination in any and combination in any or with the bus-bar room module of combination in any.
Behind described cable vault module and the bus-bar room module assembled, assemble again the power house module, the power house module after when maintenance, integral body shifted out,, the mutually metal partion (metp) of sealing isolation module and cable vault's module at the anterior dismounting of cabinet bus-bar room.
Of the present invention have advantage and beneficial effect really is, since the present invention adopted by solid dielectric insulation coat respectively be packaged into the cabinet module, power house module, cable vault's module and bus-bar room module, and be connected to form monolithic construction by keeper, mutually seal isolation by metal partion (metp) between each module, so its compact conformation is reasonable in design, parts are realized modularization, precision is high, loop resistance is little, dielectric strength is high, and interchangeability is good.Because modularization has been dwindled small product size greatly, thus manufacture craft simple, reduced the installation and maintenance difficulty, be convenient to on-the-spotly install, debugging, safe and reliable, also can reduce product cost simultaneously.The bus-bar room module is positioned at top, cabinet rear portion, can be prefabricated in advance.Cable vault's module is positioned at the cabinet bottom, also can be prefabricated in advance.The power house module is positioned at the top of cabinet front portion, and wherein independently the control room can dispose according to customer requirements the secondary component such as integrated protection, lamp, button, control device of different manufacturers.Can also realize the power house module when maintenance integral body shift out, after the power house module shifts out, bus that can be in cabinet front maintenance bus-bar room module and the solid insulation mutual inductor unit in cable vault's module.For different schemes into and out of line, just can realize the multi-scheme combination as long as change cable vault's module.
In sum, the present invention has reached veritably switchgear and has made up at the scene, leaned on the purpose that wall is installed, cabinet overhauls previously, the volume that has solved existing switchgear existence is large, power supply continuity is poor and adopt solid insulation to eliminate the problems such as SF6 contaminated environment, make especially switchgear can exempt to be influenced by the adverse circumstances, increase the service life.
