Abstract

The invention relates to an electrical cabinet and a control circuit for a cabinet door intelligent lock and a protective door intelligent lock of the electrical cabinet. The control circuit comprisesa power supply, a cabinet door branch circuit, a first protective door branch circuit and a second protective door branch circuit; a cabinet door switch, a primary side of an induction coil and a cabinet door lock body for locking a cabinet door are arranged on the cabinet door branch circuit in series; a cabinet door microswitch, a protective door microswitch and a protective door lock body forlocking a protective door are arranged on the first protective door branch circuit in series; and the second protective door branch circuit is connected with the protective door lock body in parallel,a secondary side of the induction coil and a linkage switch are arranged on the second protective door branch circuit in series, and the linkage switch is in linkage with the protective door microswitch and is opposite to the protective door microswitch in linkage state. On one hand, the protective door can be opened only after the cabinet door is opened, so that the electrical cabinet can normally operate and work; and on the other hand, the cabinet door can be closed only after the protective door is closed, misoperation is prevented from occurring when the protective door is closed, and the safety coefficient is high.

Description

technical field [0001] The invention belongs to the technical field of electric power system protection, and in particular relates to an electric cabinet and a control circuit of an intelligent lock for a cabinet door and an intelligent lock for a protective door. Background technique [0002] The current electrical cabinets, such as charging cabinets, are equipped with expensive power modules inside the cabinet. The power module is the core of the charging cabinet and an important part of the charging cabinet. The landing door structure is respectively the cabinet door arranged on the outer layer and the protective door arranged on the inner layer. [0003] Today's cabinet doors and protective doors all adopt a door-opening structure, which brings convenience to technicians. In order to ensure the safe use of the charging cabinet, a safety protection structure is provided on the cabinet door and the protective door. However, the protective structure of most cabinet doors ...
