Abstract

The invention discloses a distribution box protection module. According to the distribution box protection module, a current sensor, a humidity sensor and an auxiliary current sensor are arranged in a distribution box to monitor whether the current in the distribution box is leaked due to a short circuit or not or whether the humidity in the distribution box is excessively high or not or whether the static electricity content is excessively high or not, if the values exceed the standard values, a circuit is cut off through an electromagnetic relay, the safety is guaranteed, and situations such as fire hazards are avoided.

Description

technical field [0001] The invention designs a distribution box protection module, which belongs to the field of electric appliances. Background technique [0002] In some working conditions with relatively poor environment, or when the electrical appliances in the distribution box are relatively old, the circuit often has leakage, poor contact, and arcing of contacts is discharged into the air, which can easily cause electric shock , fire and other hazards. Contents of the invention [0003] The object of the present invention is to provide a technical solution capable of solving the above problems. [0004] The present invention is realized by following method: [0005] A distribution box protection module, including a power distribution box three-phase circuit and a user three-phase circuit, the protection module also includes a current sensor, an auxiliary current sensor, a humidity sensor, a main control module, a transformer and an electromagnetic relay, the curren...
