The embodiment of the invention provides a plugging device and method for an explosion-proof cable connector, the plugging device comprises a first cable connected with a power supply, and the first cable is provided with a first sensor; the second cable is connected with electric equipment; the second sensor is arranged on the second cable; the second sensor is connected with the first cable through the plug and the socket of the connector; the locking mechanism is used for locking or unlocking the plug and the socket and judging whether the connector can be operated or not; the controller is connected with the first sensor, the second sensor and the locking mechanism. According to the embodiment of the invention, the plug and the socket of the explosion-proof cable connector cannot be plugged when the explosion-proof cable connector is electrified, and can be plugged when the explosion-proof cable connector is not electrified, so that potential safety hazards caused by electrified plugging of the explosion-proof cable connector due to human factors or reverse discharge of electric equipment are avoided.
Description
technical field [0001] The invention relates to the technical field of explosion-proof cable connectors, in particular to a plugging device and method for explosion-proof cable connectors. Background technique [0002] Explosion-proof cable connectors used in explosive environments (such as coal mines containing gas, chemical plants containing flammable and explosive gases, etc.) are hereinafter referred to as explosion-proof cable connectors. It is mainly composed of two parts, a plug and a socket, which can realize the quick connection and disconnection of the power supply and the electrical equipment. When in use, the plug and socket must be installed in place to be powered on. Explosion-proof cable connectors can only be plugged and unplugged without power on (where plugging means connection, and pulling out means disconnection) to ensure safety; when plugging and unplugging explosion-proof cable connectors with power on, the sparks or arcs generated may ignite the surro...
