Now popular combined electrical apparatus is divided into two kinds of open type and totally enclosed types by insulation system on the market.Open type is each element to be connected according to the appliance wiring requirement combine no special seal between each element.Totally enclosed type is that the electrification in high voltage position with each element is sealed in the grounded metal enclosure, fills in the shell with the good SF6 gas of insulation property, and each element connects to form an integral body successively.Open combined electri cappliance has the deficiency that floor space is bigger, Installation and Debugging are difficult and reliability is low because of its version.And the totally enclosed type combined electrical apparatus is because inner cause of filling SF6 gas; Can cause following problem: 1, SF6 gas belongs to hot room gas; 6 kinds of greenhouse gases in the Kyoto Protocol that passed through in 1997, pointing out; SF6 is the strongest a kind of of greenhouse effect, and its greenhouse effects of the earth coefficient is CO
223900 times, the life-span in atmosphere is 3200, is using the great risk that generation pollutant sources contaminated environment is arranged with removal process; 2, equipment fault accident is serious, because the equipment sealing is installed, in case inner element has an accident, can cause the inefficacy of whole equipment to be scrapped; 3, safeguard inconvenience, the overhaul of the equipments time is long; 4, extra gas detection equipment and ventilation equipment will be installed in the equipment field of employment, increase the production run cost.
Summary of the invention
The shortcoming that the objective of the invention is to overcome prior art is with not enough, and providing a kind of does not only have SF6 gas risk but also can solve the compact combined electrical apparatus that the big reliability of open combined electri cappliance volume is hanged down defective.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of compact combined electrical apparatus that seals admittedly of the present invention; Comprise breaker unit, Disconnecting switch unit, current transformer unit, earthed switch unit and the operating mechanism of fixed sealing type, said breaker unit, Disconnecting switch unit, current transformer unit, earthed switch unit and operating mechanism are assemblied on the same framework; The primary conductive part of said breaker unit and the moved end of Disconnecting switch unit primary conductive combine to seal the insulation form admittedly; The quiet end of said Disconnecting switch unit primary conductive is arranged separately on the framework, and the moved end of Disconnecting switch unit and quiet end form insulation gap; Said current transformer unit one end is installed on the pole of breaker unit, and the fixed contact of the other end and ground connection is combined into one.
Preferably, said Disconnecting switch unit is arranged on the top of breaker unit, and the fixed contact of Disconnecting switch unit is installed in the cover type insulating cylinder, and the moving contact of Disconnecting switch unit is rectilinear motion up and down.
Preferably, said breaker unit is the breaker vacuum arc control device.
Preferably, said breaker vacuum arc control device are sealed by epoxy resin admittedly, and the moved end of breaker vacuum arc control device and Disconnecting switch unit is combined into an integral body, and the quiet end of breaker vacuum arc control device is connected through fingertip with the Disconnecting switch unit moved end.
Preferably, the stationary contact of said earthed switch unit and current transformer leading-out terminal are combined into an integral body, and earthed switch unit three-phase moving contact is the disconnecting link form.
Preferably, said operating mechanism is detachable spring operating mechanism.
The present invention has following advantage and effect with respect to prior art:
1, the present invention has substituted the SF6 greenhouse gas, adopts vacuum extinction and epoxy resin external insulation, makes to cut-off the combined electrical apparatus that making capability and insulation property are much higher than the SF6 gas-filled type.
2, the present invention's design has the Direct Action Type isolating switch of obvious fracture, and insulating contact adopts air insulation up and down, and no organism connects between contact, no condensation risk, and security performance is high.
3, the present invention adopts the epoxy resin technology packet, when improving the primary circuit insulation property, has reached compact conformation, miniaturization and non-maintaining good result.
4, the present invention adopts the dismantled and assembled spring operating mechanism of modularization to realize long-life, the premium properties of high reliability and easy access.
