Description

Technical Field

[0001] The utility model belongs to the technical field of control cabinet fire protection, and in particular relates to a control cabinet for electrical equipment. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or an alarm can be issued with the help of protective electrical appliances. Various parameters in operation can be displayed with the help of measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals when deviating from the normal working state. The control cabinet is mainly used to receive high and low water level control signals output by DXYK, DGYK, DXYW, DFYK series liquid level controllers (devices), and control the automatic start and stop of electric equipment and starting equipment. Its control forms include full-voltage starting, reduced-voltage starting, soft starting, frequency conversion control, etc.
