Description
Technical field
The utility model discloses a kind of full-insulated full-sealed ring main unit, belong to field of power, is ring main unit technical field more specifically.
Background technology
Since nearly half a century, electric power industry development is very fast, and new technology and new equipment continue to bring out.Wherein gas-insulated switchgear (English full name Gas Insulator Switchgear, be called for short GIS), owing to having adopted gas insulation technology, can not be subject to the impact of external environment, move not only safe and reliable but also non-maintaining, and have that volume is little, the advantage such as floor space is few, therefore standby popular with users, develop very fastly, be widely used in all kinds of power supply-distribution systems.
Electric equipment is mainly made up of electric conductor (conductor) and insulation (insulator).Various insulating material (claiming again dielectric) will be isolated between the electric conductor of equipment different potentials and with the earth reliably.Insulator is the key component in electric equipment, is simultaneously also weaker part, its performance quality determining equipment and system can be safely, move reliably.Prevailing in power engineering is to adopt air dielectric as the external insulation (insulation of device housings outside) of electric equipment, but experiment shows, the puncture voltage of same air gap under different atmospheric conditions is different.Because atmospheric pressure, temperature and humidity all can affect the density of air, free travel, ionization by impact and the adsorption effect of electronics, certainly will affect the puncture voltage of air gap.Therefore, air-insulated conventional controller switching equipment (English full name Air Insulated Switchgear, be called for short AIS), strengthen the places such as the inconvenient high altitude localities of external insulation and operational environment humidity, pollution severity, many dirt is rocky owing to only relying on air and insulator to make live part and ground, insulation between phase and phase, not being adapted to be mounted within.
The purpose of this utility model is, provide that a kind of reliability is high, security performance good, there is no the danger of getting an electric shock, and can isolate even flood of salt fog, laying dust, moisture completely, not be subject to the impact of external condition, improve widely the full-insulated full-sealed ring main unit of reliability.
Summary of the invention
For the problems referred to above, a kind of full-insulated full-sealed ring main unit, comprises stainless steel cabinet, controller cabinet, guidance panel, cable cabinet, upper strata dividing plate and lower floor's dividing plate; Wherein, described controller cabinet is arranged on the topmost of described stainless steel cabinet, and described guidance panel is arranged on the middle part of described stainless steel cabinet, and described cable cabinet is arranged on the bottom of described stainless steel cabinet; Between controller cabinet described in described upper strata dividing plate is arranged on and described guidance panel, between the guidance panel described in described lower floor's dividing plate is arranged on and described cable cabinet; In described controller cabinet, be provided with controller and storage battery, fuse support and fuse; In described cable cabinet, be provided with coupling box and over-pressure safety device.
As further restriction, on described guidance panel, be provided with air gauge, cable cabinet door switch, grounded circuit handle hole, grounded circuit status indicator lamp, major loop status indicator lamp, major loop handle hole and potential indicator.
As preferably, described stainless steel cabinet is the gas tank that adopts stainless steel welding, and has hermetically sealed characteristic.
As preferably, in described stainless steel cabinet, adopt the SF6 gas of insulation property brilliance to do and insulate and arc-extinguishing medium.
As preferably, the coupling box in described cable cabinet adopts the DIN sleeve structure of special seal means.
As preferably, the mode of the screw thread that the outlet of this full-insulated full-sealed ring main unit and entrance bushing are all taked is fixed.
The utlity model has following advantage:
(1) stainless steel cabinet adopts all-sealed structure, and hermetic once encapsulation, is not subject to the impact of environment.For example: flood, humidity and toy, it is non-maintaining that the gas tank of all-welded structure can reach, the not impact of climate, the space minimum taking;
(2) integrated level is high.Insulate and arc-extinguishing medium because adopt the SF6 gas of insulation property brilliances to do, can make between combined electrical apparatus conductor, the minimum electrical distance of conductor between over the ground greatly dwindle, and can significantly dwindle the volume of electric substation, realizes miniaturization;
(3) reliability is high.Because band high-tension electricity part is all sealed in stainless steel casing, degree of protection reaches IP67, isolates even flood of salt fog, laying dust, moisture completely, is not subject to the impact of external condition, has improved widely reliability;
(4) security performance is good, is all sealed in the metal shell of ground connection, thereby there is no the danger of getting an electric shock with high-tension electricity part, and SF6 is again non-flammable compressive gas, so also there is no fire hazard.
