The invention discloses a spring mechanism self-check breaker specially for electric power operation and maintenance. The spring mechanism self-check breaker comprises an arc extinguishing chamber, abase and adsorbers, the bottom of the base is provided with support legs, the lower side of the internal part of the base is provided with a gas pipeline, current transformers are arranged above transformer connection protection pipes, the current transformers are electrically connected with on-off indicating lamps, magnetic sleeves are arranged above the current transformers, and wire-outlet capsare arranged above the magnetic sleeves. According to the spring mechanism self-check breaker, the temperature in the arc extinguishing chamber can be detected, a ceramic semiconductor wafer is provided so that refrigeration cooling is performed by employing low electric power, less electric energy can be consumed compared with a conventional fan, the usage cost performance is high, intelligenceand rapidity are achieved, the pulling force of a spring mechanism can be detected, if the pulling force of the spring mechanism is not in a prescribed range, it is indicated that the spring mechanismis possibly damaged, a maintainer can be notified of maintenance in time, the probability of fault occurrence for a circuit is reduced, and the usage is highly efficient and intelligent.
Description
technical field [0001] The invention belongs to the technical field of electric power operation and maintenance, and in particular relates to a spring mechanism self-inspection circuit breaker dedicated to electric power operation and maintenance. Background technique [0002] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current. At present, it has been widely used. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called...
