Abstract
The utility model belongs to a high-voltage electrical appliance, and particularly relates to a plate spring stress application disconnecting link device for a high-voltage isolating switch. The plate spring stress application disconnecting link device consists of a current conducting tube (1), a sensing finger seat (2), a plate spring (3), a sensing finger (4), a contact (5) and a plug (6), wherein sufficient contact pressures between the current conducting tube and the sensing finger seat as well as between the current conducting tube and the contact are ensured through the interference fit of the plug and the fit of the arranged plate spring. The contact pressure of the plate spring stress application disconnecting link device is stable and reliable under the same condition, so that the plate spring stress application disconnecting link device has large current-carrying capacity and stable electric performance, has a simple process and low production and maintenance costs, and is convenient to maintain, and the electric reliability of the high-voltage isolating switch is enhanced integrally. The plate spring stress application disconnecting link device has high adaptability to severe natural environment, can work under the conditions of flurry, dust and sand, frost, dew drops and the like, and is suitable for working occasions such as open air and the like.
Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances, the afterburning formula high voltage isolator of particularly a kind of leaf spring disconnecting link device.
Background technology
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, is to play buffer action in circuit.Itself operation principle and relatively simple for structure, but because use amount is big, functional reliability requires high is all bigger to the influence of design, foundation and the safe operation of electric substation, power plant.High voltage isolator be used for branch, close the no load condition circuit, safety is isolated repair apparatus and change-over circuit; And should be able to pass through rated current reliably in running status.High voltage isolator present and that this technology is more approaching has GW4, the GW5 type, its current-carrying part is by static contact seat, fingertip, leaf spring and contact constitute, the operation principle of its contact is: provide between stationary contact seat and fingertip and the contact pressure between cylindrical contact and fingertip by spring, the fingertip that is distributed in contact seat both sides during combined floodgate contacts with cylindrical contact is electric, the contact site of its contact only limits to the contact both sides, thereby contact wire grows up to the principal element for restriction contact current-carrying capacity, therefore contact is subjected to the influence of external environment condition when current-carrying moves, and for example dust and high temperature etc. very easily cause the contact heating; Constitute bridge circuit because of the contact of fingertip and spring on the other hand, the fingertip resistance unbalance increases, and causes the spring shunting, when spring heating annealing, quickens the contact heating, causes finally that contact is overheated to be burnt, and causes electric accident.
The utility model content
The purpose of this utility model is to solve above shortcoming, this disconnecting link device is in leading electric part optimal design and improve the fingertip material, has overcome the defective of existing contact heating in the prior art, has improved the current capacity of contact, and simple in structure, debug easy to maintenance.The technical scheme that realizes above-mentioned purpose is:
The current-carrying part of the disconnecting link device of this isolating switch adopts the board-like spring structure of external pressure, and contact tube and fingertip seat, contact tube and contact all are to guarantee enough contact pressures by the interference fit of filling in this structure, compress into hydraulic press during assembling.Current-carrying part adopts board-like fingertip to cooperate structure of contact terminal, and the fingertip material is a chromium-bronze, and contact material is a red copper, by the difference in size between the accessory, makes fingertip produce deformation, meets the requirements of contact pressure.For guaranteeing constant pressure, increase leaf spring in the fingertip outside, be connected on the fingertip seat with bolt.The afterburning formula high voltage isolator of a kind of leaf spring disconnecting link device is made up of contact tube, fingertip seat, leaf spring, fingertip, contact and plug, and it is characterized in that: contact tube and fingertip seat, contact tube and contact all are to guarantee enough contact pressures by the interference fit of filling in.It is material that contact adopts red copper.It is material that fingertip adopts chromium-bronze, increases leaf spring in the fingertip outside, is connected on the fingertip seat with bolt.
Beneficial effect:
The utility model under the same conditions, contact pressure is reliable and stable, thereby it is big to have current-carrying capacity, and electric property is stable, has improved the electric reliability of high voltage isolator on the whole, technology is simple, easy to maintenance, production and maintenance cost are low, and be stronger to the adaptive capacity of extreme natural environment, can under conditions such as wind and snow, sand and dust, the Frost's Descent, condensation, work, be applicable to workplaces such as balcony.
