Abstract
The invention discloses an arc extinguishing breaker apparatus dedicated to a power high-voltage distribution line. An upper grading ring is installed on the top of a wire-outlet porcelain bushing. A binding post is installed on the top of the upper grading ring. The wire-outlet porcelain bushing is formed by processing insulated ceramic. The upper grading ring is a metallic ring. The binding post is a fixed terminal. A lower grading ring is fixedly installed on the bottom of the wire-outlet porcelain bushing and is fixedly installed on the housing. An arc extinguish chamber, a fixed contact, and an insulator are disposed in the housing. The fixed contact is fixedly installed on the insulator. One side of the arc extinguish chamber communicates with a connecting lever case. The bottom of the connecting lever case is connected with a mechanism case. A current transformer is installed on the upper right part of the housing and at the wire-outlet porcelain bushing side and is connected in series with a cable. The bottom of the housing is fixed to an installing frame. The arc extinguishing breaker apparatus dedicated to power high-voltage distribution line is rational and reasonable in design, simple in structure, and flexible and convenient to use, and has wide application prospect.
Description
Technical field
The present invention relates to a kind of chopper, especially relate to the arc extinguishing breaker apparatus that a kind of power high voltage distribution line is special, 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.
Summary of the invention
The present invention proposes the arc extinguishing breaker apparatus that a kind of power high voltage distribution line is special, and its design science is reasonable, and structure composition is simple, flexible and convenient to use, has boundless application prospect.
Solution of the present invention solves existing technical problem by the following technical solutions.
The arc extinguishing breaker apparatus that a kind of power high voltage distribution line is special, structure includes: binding post, upper grading ring, outgoing line porcelain bushing pipe, lower uniform pressure ring, crank arm box, mechanism case, installing rack, arc-chutes, static contact, insulator, housing, current transformer, grading ring is installed at described top porcelain bushing shell occur, binding post is installed on the top of upper grading ring, described outgoing line porcelain bushing pipe is to adopt insulating ceramics to process, upper grading ring is becket, and binding post is fixing terminal, the bottom fixed installation lower uniform pressure ring of described outgoing line porcelain bushing pipe, lower uniform pressure ring is fixedly mounted on housing, arranges arc-chutes in described housing, static contact, insulator, described insulator fixedly mounts static contact, the side of arc-chutes connects with crank arm box, the bottom of described crank arm box is connected with mechanism case, the upper right quarter of described housing installs current transformer, described current transformer is arranged on the side of outgoing line porcelain bushing pipe and connects with cable, and the bottom of described housing is fixed on installing rack.
The invention has the beneficial effects as follows: the special arc extinguishing breaker apparatus of a kind of power high voltage distribution line that the present invention proposes, its design science is reasonable, and structure composition is simple, flexible and convenient to use, has boundless application prospect.
