The invention discloses an electric power drawer cabinet monitoring device and a drawer type switch cabinet. The electric power drawer cabinet monitoring device comprises a power supply module and a monitoring module which are electrically connected. The power supply module is used for providing working voltage for the monitoring module; the monitoring module is used for detecting the opening and closing states of the drawer of the electric power drawer cabinet, the opening and closing states comprise an opening state and a closing state, and recording the number of times that the drawer is in the opening state and / or the closing state so as to determine the use condition of the electric power part in the electric power drawer cabinet according to the number of times that the drawer is in the opening state and / or the closing state. According to the invention, the use condition of the electric power part in the electric power drawer cabinet is determined according to the number of times that the drawer is in the opening state and / or the closing state, so that compared with the prior art that only the opening or closing state of the switch cabinet is detected, the state of the electric power part in the electric power drawer cabinet can be monitored; operation faults of the electric power drawer cabinet caused by serious abrasion of electric power components are avoided, and the reliability of the electric power drawer cabinet is improved.
Description
technical field [0001] The application relates to the technical field of electric equipment, in particular to a monitoring device for a power drawer cabinet and a drawer type switch cabinet. Background technique [0002] Drawer Type Switch Cabinet (Drawer Type Switch Cabinet) is a closed shell made of steel plate. The electrical components of the incoming and outgoing circuit circuits are all installed in drawers that can be drawn out to form a functional unit that can complete a certain type of power supply task. The functional unit of the drawer switch cabinet is separated from the bus bar or cable by a grounded metal plate or a functional plate made of plastic to form three areas: bus bar, functional unit and cable. Usually, each drawer of the drawer-type switchgear includes multiple components such as incoming line connectors, outgoing line connectors, molded case circuit breakers, digital display meters, and transformers. [0003] At present, in order to ensure the nor...
