Description
Technical Field
The utility model relates to a circuit breaker technical field specifically is a seal novel circuit breaker utmost point post admittedly.
Background
The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. The circuit breaker can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, automatically cutting off a circuit when faults such as serious overload, short circuit, undervoltage and the like occur, has the function equivalent to the combination of a fuse type switch, an over-under-heat relay and the like, does not need to change parts after breaking fault current, and is widely applied at present.
In a conventional circuit breaker, an insulating shell of a general vacuum arc-extinguishing chamber is exposed in air, and the problem of pollution caused by external dust and moisture exists. To reduce this effect, the housing of the vacuum interrupter is required to have a sufficient length, which affects not only the miniaturization of the vacuum interrupter but also the performance and reliability of the vacuum interrupter.
With the development and progress of the technology, the embedded pole can well solve the problems, namely, the vacuum arc-extinguishing chamber and the related conductive parts of the circuit breaker are simultaneously embedded into the easily-cured solid insulating materials such as epoxy resin or thermoplastic materials to form the pole, so that the whole pole of the circuit breaker becomes an integral part. The solid-sealed polar pole has the following advantages: compared with the traditional assembled pole, the number of parts of the solid-sealed pole is greatly reduced, the overlapping surface of the conductor and the connecting bolt are obviously reduced, and the reliability of the circuit breaker is greatly improved due to the simple structure; because the vacuum arc-extinguishing chamber is embedded into the solid material, the solid-sealed pole can achieve high insulating strength without any further treatment; after the vacuum arc-extinguishing chamber is embedded into the solid material, the influence of the external environment of the pole on the vacuum arc-extinguishing chamber is reduced to the minimum.
However, during operation, the upper wire outlet seat, the vacuum arc-extinguishing chamber, the lower wire outlet seat and the like of the solid-sealed pole generate heat, which seriously affects the working performance and the service life of the circuit breaker; in addition, the circuit breaker is continuously developing towards miniaturization, large capacity and high voltage, which all make the temperature rise in the circuit breaker higher and higher; in addition, the heat dissipation of the circuit breaker can only depend on heat conduction, and the temperature rise problem is more prominent when the rated current is higher. The excessive temperature rise has great influence on the mechanical strength of the conductor material, and is easy to oxidize the surface of the conductor metal material, the generated oxide increases the contact resistance to influence the loop resistance and the electrical performance of the circuit breaker, and the aging of the insulating part is accelerated by the excessive temperature rise. Therefore, temperature rise caused by heating of all parts of the electric conductors of the circuit breaker must be limited, and effective measures are taken to evacuate and discharge heat in time.
