Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
An emergency linkage control fire-fighting cabinet comprises a cabinet body 1 and a fixing frame 2, wherein the fixing frame 2 is fixedly arranged in the cabinet body 1, a mounting plate 3 and a supporting bar 4 are fixedly arranged in the fixing frame 2, the mounting plate 3 is vertically arranged in the middle of the fixing frame 2, the supporting bar 4 corresponds to the mounting plate 3 and is positioned on the front end face of the mounting plate 3, a manual control unit is fixedly arranged on the supporting bar 4, an automatic control unit 5 for automatic star-delta starting is fixedly arranged on the rear end face of the mounting plate 3, the manual control unit comprises a first isolating switch 6, a second isolating switch 7 and a third isolating switch 8, and the third isolating switch 8 is used for controlling the manual control unit to be connected with a power grid; wherein all be fixed with the transmission piece on first isolator 6's the dwang, second isolator 7's the dwang, be provided with on the mount 2 along vertical direction 2 dogs 11 corresponding from top to bottom, dog 11 is worn out to connecting wire 10, and fixed transmission piece 9 is fixed mutually on the one end of connecting wire 10 and first isolator 6's the dwang, and fixed transmission piece 9 is fixed mutually on the other end of connecting wire 10 and second isolator 7's the dwang. Meanwhile, the outer side of the connecting wire 10 is sleeved with a limiting sleeve 12, one end of the limiting sleeve 12 is fixed with the stop block 11 above, and the other end of the limiting sleeve 12 is fixed with the stop block 11 below.
The automatic control unit 5 comprises a circuit breaker, a relay and a time delay relay, the star triangle automatic starting of the pump is realized through the circuit breaker and the relay primary time delay relay, and the pump is controlled to be started in a star triangle connection mode.
The utility model discloses a working process: the fixing frame 2 is fixedly installed in the cabinet body 1, cabinet doors convenient to install and maintain are arranged on the front side and the rear side of the cabinet body 1, and automatic star-triangle conversion starting of the pump machine is achieved through an automatic control unit 5 formed by electrical elements on the installation plate 3 during normal work. First isolator 6, second isolator 7, third isolator 8 all are in the off-state under initial condition, when automatic control unit 5 broke down and can't normally work and need emergent start-up, the operator who has fire control cabinet operation authority now makes manual control unit access electric wire netting with the closed switch-on K terminal of third isolator 8, then the operation rotates first isolator 6 closed QA1, QA2 terminal of first isolator 6 this moment and all closes to realize the star connection of pump machine and start. After the pump is started by installing the star connection for several seconds, the QA1 and QA2 terminals of the first isolating switch 6 are rotated reversely, and the QB1 terminals are connected by rotating the second isolating switch 7 forwardly, so that the star connection of the pump is changed into the triangular connection.
