Abstract
The invention relates to a novel 6-10kV clip piece type isolation switch, which mainly comprises a conductive part, a fixed base, supporting porcelain insulators, a transmission part and an operating mechanism; a moving contact rod is a hollow cylindrical conductive rod, a static contact is a double-row self-operated finger, and a contact end is an opening; contact fingers are made of high-strength, high-conductivity and high-elasticity materials, the surfaces of the contact fingers are coated with silver. According to the isolation switch, a traditional clip piece type structure is changed to a handshake structure, the conductive performance of the isolation switch is improved, and overheating accidents are eradicated.
Description
Technical field
The present invention relates to the technology of isolating switch, specifically the structure technology of 6-10kV clip type disconnecting link conductive contact.
Background technology
At present, the isolating switch conductive contact part at network operation, is the way of contact of handshaking type structure, and its contact is plug-in type, has from cleaning ability, and fingertip one end is fixed on contact base, forms fixing contact, has the reliable advantage of conduction; By external-compression type reed and fingertip self elastic force, contact is produced to contact, short circuit current by time can automatically increase contact clamping force.Conduction contact part is silver-plated, has the advantages such as contact resistance is little, simple and reliable for structure.And at the 6-10kV of network operation isolating switch, owing to being subject to environment, the restriction of installation site etc., cannot accomplish to adopt the form of handshaking type structure, what make this model isolating switch still continues at network operation the way of contact that adopts traditional clip type structure, current-carrying part is mainly comprised of contact knife (moving contact) and fixed contact, contact knife (moving contact) both sides copper sheet is by spring compression, long-play is under the effect of electric current, holddown spring is aging, inadequate to contact knife (moving contact) both sides copper sheet thrust, easily cause the superheating of crossing of galvanic circle, directly have influence on user security, power supply reliably.For this reason, how to avoid, due to the overheated abnormal problem causing of the dynamic and static contact of isolating switch, seeming particularly important.
Summary of the invention content
The object of the invention is to: change the way of contact of 6-10kV clip type disconnecting link dynamic/static contact, by traditional clip type frame mode, change into handshaking type structure, improve isolating switch electric conductivity, stop overheat accident and occur.
Concrete technical scheme of the present invention is:
The present invention's 6-10kV isolating switch structure, the same with conventional 6-10kV isolating switch, mainly by current-carrying part, firm banking, supporting insulator porcelain vase, running part, operating mechanism, formed.Dynamic and static contact is arranged on respectively on two supporting insulators that are fixed on above underframe, in the middle of movable contact rod, pull bar porcelain vase is housed, and three parallel installation.Pull bar porcelain vase is connected with the main shaft being arranged on underframe, and the two ends of main shaft are protuberate basic unit all, and main shaft is equipped with connecting lever, by connecting lever, is connected with operating mechanism with connecting rod.
The present invention is mainly dynamic and static contacts Technology.Movable contact rod is open circles column type conducting rod, and fixed contact is double self-reliance fingertip, single three fingertips, and each fingertip width 15mm, contact jaw is uncovered; Fingertip adopts high strength, high conductivity, elastomeric material manufacture, electroplate.Rely on the elastic force clamp contact of fingertip self, avoided the contact clamping force causing because of spring corrosion, heating annealing at present to reduce, contact resistance increases, the vicious circle of contact heating aggravation.When dynamic and static contact divides, closes a floodgate, also there is the ability of automated cleaning contact, improved contact reliability and useful life.
Below in conjunction with drawings and Examples, the present invention will be further described.
