Reusable power circuit breaker based on thermal expansion and cold contraction

Abstract

The invention discloses a reusable power circuit breaker based on thermal expansion and cold contraction and relates to the technical field of power. The reusable power circuit breaker comprises a mounting base, a movable groove is formed in the middle of the mounting base, a first spring is fixedly connected to an inner bottom wall of the movable groove, a sliding block is fixedly connected to the top of the first spring, a dielectric plate is fixedly connected to the middle of the sliding block, and a positive plate is fixedly connected to a left side of an inner wall of the top of the mounting base. According to the reusable power circuit breaker based on thermal expansion and cold contraction, the dielectric plate is matched with a resistor for use; when the voltage of the circuit is too high; the temperature of an electric heating block rises; compressed gas at the bottom of the movable groove is heated, the compressed gas is expanded to lift the sliding block upwards, so the relative area of the positive plate and a negative plate of the dielectric plate is reduced, the voltage passing through the resistor is reduced, and when the voltage is smaller than the minimum access voltage, the circuit is in a short circuit state such that the automatic power-off effect is achieved, the safety of the circuit is effectively protected, the safe use of machinery is guaranteed, and the loss is avoided.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a reusable power circuit breaker based on thermal expansion and cold contraction. Background technique [0002] Electricity is a kind of energy that is often used in our daily life. The invention of electricity has greatly improved the quality of human life, enabling people to see things clearly at night, and making it easier for people to manufacture at night. [0003] Most of the current mechanical equipment relies on electricity to work, and most of the current large-scale mechanical equipment is high-power machinery. When used, the total power generated is relatively large, which places a heavy burden on the circuit, and sometimes even causes the circuit to be burned.

Problems solved by technology

[0003] Most of the current mechanical equipment relies on electricity to work, and most of the current large-scale mechanical equipment is high-power machinery. When used, the total power generated is relatively large, which places a heavy burden on the circuit, and sometimes even causes the circuit to be burned. It will affect the production efficiency, and the burning of the line will also cause the circuit failure of the machine, affect the use of the machine, cause the production rate to be seriously affected, and bring irreparable losses to the factory

Most of the current circuits are equipped with a circuit breaker, but the current circuit breaker will automatically cut off the power when the total power is too large. When the total power returns to the normal level, it will not restore the connection state, requiring manual operation However, the installation height of the circuit breaker is relatively high, and it is difficult to operate. There are certain safety hazards in manual operation, which may easily lead to safety accidents.
