Abstract
The invention discloses a protective cover of an isolating switch. The protective cover comprises a base, an insulating pillar, a wiring base, a left contact and a right contact, wherein the insulating support is fixed on the base, the electricity conducting wiring base, a left contact conducting tube and a right contact conducting tube are installed on the insulating pillar, the left contact and the right contact are respectively connected at the ends of the conducting tubes, contact fingers are connected onto contact finger bases through bolts, and the contact finger bases are sleeved at the ends of the conducting tubes; and the protective cover is covered on the contact finger bases in reverse mode and fixed with the contact finger bases through pins. The protective cover can reduce damage to electrical devices from the environment, accordingly enables operation of the electrical devices to be safe and reliable and prolongs service life.
Description
Technical field
The present invention relates to the switching technique field, especially relate to a kind of isolating switch protective cover.
Background technology
Advantage is extensively applicable in transformer station because having dependable performance, simple in structure, installation and repairing is easy, applied widely, versatility, series are strong etc. for outdoor high-voltage isolating switch, this type of switch is for a long time in outdoor operation, Exposure to Sunlight, drench with rain, the various environmental factors such as dust all can cause damage to electric equipment, service conditions is very abominable, in the case, because above-mentioned switch does not arrange safeguard procedures, cause the normal operation that may affect electrical network, reduce power supply reliability.Therefore be necessary to be improved.
Summary of the invention
The object of the invention is to the weak point that exists for prior art, a kind of outdoor high-voltage isolating switch with protective cover, safe and reliable to operation, long service life is provided.
The isolating switch protective cover that the present invention proposes, comprise base, insulation column, junction block, left contact, right contact, insulation column is fixed on base, band conductive connection seat, left and right contact contact tube are housed on insulation column, left contact, right contact are connected to its contact tube end, and fingertip is connected on button contact base, and button contact base is set in the contact tube end, also comprise protective cover, described protective cover tips upside down on described button contact base.
Isolating switch protective cover of the present invention, its diapire of described protective cover is fixed by a pin on described button contact base, and its perisporium covers in the outside of described button contact base and contact fingertip.
After adopting said structure, the present invention compared with prior art, have the following advantages: owing to having adopted protective cover, can make outdoor high-voltage isolating switch effectively anti-than Exposure to Sunlight, drench with rain, dust etc., reduce environment to the infringement of electric equipment, thereby guarantee the normal operation of switch and electric equipment, and extend its useful life.
Description of drawings
Further set forth the present invention below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, isolating switch protective cover of the present invention is described.
Embodiment 1.
As shown in Figure 1, the isolating switch protective cover, comprise base, insulation column, junction block, left contact, right contact, insulation column is fixed on base, band conductive connection seat, left and right contact contact tube 1 are housed on insulation column, left and right contact is connected to its contact tube 1 end, and fingertip 3 is connected on button contact base 2 by bolt 4, and button contact base 2 is set in contact tube 1 end; Also comprise protective cover 5, described protective cover 5 tips upside down on described button contact base 2, and its diapire is fixed on described button contact base 2 by pin 6, and its perisporium covers in the outside of described button contact base 2 and contact fingertip 3.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
