Abstract
The invention discloses a high-voltage oil-minimum breaker in a high-voltage transmission line. A lead hat is installed on the top of an oil-gas separation chamber. An upper binding post is installed under the oil-gas separation chamber. A socket-style fixed contact is installed under the upper binding post. An oil pointer is installed on a side of the upper binding post. An arc extinguish chamber is disposed under the socket-style fixed contact. A movable contact is disposed in the arc extinguish chamber. An intermediate rolling contact is installed between the movably contact and an insulated cylinder. A lower binding post is installed on a side of the movable contact. The bottom of the movable contact is connected with a rotating shaft. The rotating shaft is connected with a connecting lever fixedly installed on a pedestal. A shunning valve and insulating oil are arranged in the insulated cylinder. An upper post insulator and a lower post insulator are arranged on the left of the insulated cylinder. The upper post insulator is connected with a circuit break spring. The high-voltage oil-minimum breaker is rational and reasonable in design, simple in structure, and flexible and easy to use, and has very wide application prospect.
Description
Technical field
The present invention relates to a kind of chopper, especially relate to the high voltage mini-oil circuit breaker equipment in a kind of ultra-high-tension power transmission line, belong to technical field of electric power.
Background technology
Electric current that chopper refers to close, carry and cut-off under normal loop condition and can close, carrying and the switching device of electric current that cut-offs under abnormal loop condition within the time of regulation. Chopper can be used to distribute electric energy; infrequently start asynchronous motor; power circuit and motor etc. are carried out protection, when there is serious overloads or the fault such as short-circuit and under-voltage when them can automatic shutdown circuit, its function is equivalent to Fuse switch and crosses the combination of underheat relay etc. And after disjunction fault current, generally need not change parts. At present, obtain a wide range of applications. Chopper is divided into primary cut-out and low-voltage circuit breaker by its use scope, and high-low pressure identification of boundaries is fuzzyyer, generally more than 3kV is called High-Voltage Electrical Appliances.
