Abstract

The invention relates to a fire pump control device and control cabinet. The fire pump control device comprises pump main circuits and pump control circuits separately connected to the pump main circuits in one-to-one correspondence. The pump main circuits comprise main circuit breakers, main contactors and main thermal relays; one ends of the main circuit breakers are used for being connected with a control power supply, and the other ends of the main circuit breakers are connected to one ends of the main contactors; the other ends of the main contactors are connected to corresponding fire pumps through the main thermal relays; the pump control circuits include isolation transformers, start-stop operation control circuits and alarm indication circuits; primary side input ends of the isolation transformers are connected between the main circuit breakers and the main contactors, and secondary side output ends are connected with the start-stop operation control circuits and the alarm indication circuits separately. The fire pump control device and control cabinet can improve the reliability.

Description

technical field [0001] The present application relates to the technical field of electrical control, in particular to a fire pump control device and a control cabinet. Background technique [0002] At present, the fire pump control cabinet widely used in our country, the wiring of the main circuit is as follows: figure 1 As shown (taking one-use-one-standby and dual-purpose-one-standby as examples), the fire pump needs to be powered by two power sources in most cases, such as figure 1 For the main power supply and backup power supply shown, the two power supplies are respectively led to the fire pump control cabinet by 5 wires, as shown in figure 1 The three phase wires (L1, L2, L3), the working neutral wire (N) and the protection wire (PE) are switched by the automatic transfer switch ATSE (Automatic Transfer Switching Equipment) to supply power to the pump. [0003] The control circuit of the current fire pump control cabinet is implemented according to the current natio...
