Background technology
Isolating switch, generally refer to high voltage isolator, be that rated voltage is at 1kv and above isolating switch thereof, in high-voltage switch electric appliance, to use maximum a kind of electrical equipment, the principles and structure of itself is fairly simple, but because use amount is large, functional reliability requires high, all larger on the impact of the design of electric substation, power plant, foundation and safe operation.The main feature of disconnecting link is without arc extinguishing ability, can only in the situation that there is no load current, not divide, closes circuit.Isolating switch is mainly used for by needing the part having a power failure to isolate reliably with live part in high voltage distribution installation, to guarantee the safety of service work.
At present the disconnecting link of isolating switch adopts steel disc or copper sheet as the manufactured materials of disconnecting link more, steel or copper easily produce oxidation under using in the left and right of water and oxygen, on surface, form layer oxide film, resistance is increased, moment caloric value increase while causing switch, easily cause the damage of switch part, shorten useful life.Therefore, be necessary to research and develop a kind of new partition switch.
At present, we retrieve the open source literature of some isolating switches, for example:
1. Chinese Patent Application No. 201320353423.2, open day on November 27th, 2013, this application case discloses a kind of high voltage isolator, it comprises disconnecting link, base, fixed contact, fixed head and post insulator, described disconnecting link comprises the copper coin and the securing member that is connected copper coin of two parallel placements, described fixed contact is mounted by means of bolts on the fixed head that lower surface is connected with post insulator, the upper and lower both ends horizontal of described copper coin is extended with the flange being wholely set with copper coin, and described flange is conflicted and is connected with bolt upper surface.Its weak point is: red copper resistance after oxidation increases, and while causing switch, moment caloric value increase, easily causes the damage of switch part, and shorten useful life.
2. Chinese Patent Application No. 201320387767.5, open day on December 4th, 2013, this application case discloses a kind of high voltage isolator, it comprises base, switch and insulated column, insulated column includes line end insulated column and leading-out terminal insulated column, lead-in wire terminal insulated column is provided with terminal block, one end of described switch is articulated with outlet insulated column, the other end matches with described terminal block, described switch is provided with metering hole, and the hinged end of the opening of described metering hole from switch and terminal block abutting end towards switch is gradually and increases.Its weak point is: switch resistance after oxidation increases, and while causing switch, moment caloric value increase, easily causes the damage of switch part, and shorten useful life.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of long service life, simple in structure, easy to operate high pressure cuts off switch.
For achieving the above object, the present invention is achieved by the following scheme:
A kind of high pressure cuts off switch, comprise base, base one end connects lambda line insulator, the other end connects outlet insulator, and outlet insulator upper end is all provided with connecting plate, and lambda line insulator upper end is hinged with disconnecting link, the other end of disconnecting link is connected with connecting plate, the material of described lambda line insulator and outlet insulator is silicon rubber, and the material of described disconnecting link is copper, and the area contacting with connecting plate is silver-plated.
The area that described connecting plate contacts with disconnecting link is silver-plated.
Described disconnecting link is divided into left disconnecting link and right disconnecting link, and the place that described left disconnecting link contacts with connecting plate with right disconnecting link is convex shape.
Compared with prior art, the present invention has following beneficial effect:
1. long service life.Compare with traditional partition switch, disconnecting link of the present invention adopts copper sheet manufacture, and the place of both contacts adopts silver-plated, utilize silver to be not easy the characteristic of oxidation, reduced the electric current while opening and closing, thereby reduced the caloric value of moment, reduce the damage of part, extended useful life.
2. simple in structure, easy maintenance.Number of spare parts of the present invention is few, on original basis, is transformed, simple in structure, and the easy maintenance in later stage is conducive to apply.
3. cost performance is high.Compare traditional partition switch, although the silver-plated cost that increased of the present invention, service time while is long, and not only cost performance is very high, also safe and reliable.
