Abstract
The utility model relates to a contact structure of a double-column horizontal open-type outdoor high voltage AC isolating switch. The contact structure includes a contact finger conduit, a contact conduit, a contact finger, and a moving contact. The contact finger conduit is provided with a contact finger at the front end, the front end of the contact finger is an outwardly opened arc, and an arced spring plate is arranged outside the contact finger. The moving contact is connected on the front end of the contact conduit via a contact block. The contact block is perpendicularly connected to the middle part of an upright plate via a horizontal plate to form a shape. The moving contact is connected with the upright plate of the shape. The horizontal plate of the contact block is connected with the contact conduit. The utility model has the characteristics of simple and reasonable structure, reliable conductivity performance, etc.
Description
Technical field
The utility model relates to the structure of contact terminal of isolating switch in a kind of electric power system, specifically a kind of outdoor high-voltage alternating current isolating switch structure of contact terminal of twin columns horizontally openable formula.
Background technology
High voltage isolator is an important device for switching in power plant and the transformer station's electrical system, and its major function is to be used for the isolated high-voltage power supply, guarantees safety inspection, and can the certain electric current of break-make.Advantages the such as wherein outdoor high-voltage alternating current isolating switch of twin columns horizontally openable formula is little with its floor space, make-break capacity is strong are widely used, in this equipment, contact partly is the crucial contact site of whole galvanic circle, in order to improve the electric conductivity of isolating switch product, guarantee the power equipment reliability of operation, be further improved for structure of contact terminal.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple and reasonable for structure that the utility model provides, the reliable twin columns horizontally openable of electric conductivity formula outdoor high-voltage alternating current isolating switch structure of contact terminal.
The technical solution adopted in the utility model is: a kind of twin columns horizontally openable formula outdoor high-voltage alternating current isolating switch structure of contact terminal, comprise fingertip contact tube, contact contact tube, fingertip and moving contact, the front end of fingertip contact tube is provided with fingertip, the front end of fingertip is outwardly open arc, and the latch plate of arc is arranged in the arranged outside of fingertip; Described moving contact is connected the front end of contact contact tube by contact block, and contact block is vertically connected on the riser middle part by transverse slat to be formed, and moving contact is connected that side of riser, and the transverse slat of contact block is connected with the contact contact tube.
The utility model adopts the fingertip of opening arc, makes things convenient for stretching into of moving contact, with fingertip arranged outside arc spring plate, can guarantee the clamping force when fingertip contacts with moving contact, forms reliable galvanic circle; The utility model adopts contact block that moving contact is connected with the contact contact tube, and is simple in structure, is convenient to make and install, and guarantees excellent conducting performance simultaneously.
