Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0010] figure 1 The fan control circuit shown includes a low-speed stop button 1SB and a stop button 3SB. The low-speed stop button 1SB is connected in series with the first intermediate relay 1KA to form a first intermediate relay control circuit. The first intermediate relay 1KA is connected to the low-speed start button 2SB and the first contact KM1 is connected in series to form the first contactor control circuit, the low-speed start button 2SB is connected in parallel with the second intermediate relay to form the self-protection circuit of the first contactor KM1, the stop button 3SB is interlocked with the first contact of the fire damper, and the high-speed control button 4SB , the high-speed start button 5SB, the second contactor KM2, the third intermediate relay 3KA, the motor protector BHQ and the second intermediate relay 2KA are connected i...

Abstract

The invention discloses a fan control line and relates to the technical field of manufacturing of fire-fighting equipment. The fan control line comprises a low-speed stop button, a stop button, a first intermediate relay control circuit, a first contactor control circuit, a first contactor self-protection circuit, a second intermediate relay control circuit, a second intermediate relay self-protection circuit, a third contactor control circuit, a second contactor control circuit, a third contactor self-protection circuit, a parallel circuit and a third relay control circuit. According to the fan control line, the problem of low utilization rate of a fan and high enterprise cost in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment manufacturing, in particular to a fan control circuit for ventilation and exhaust. Background technique [0002] With the increasing number of high-rise buildings, the fire department has increasingly strict fire safety requirements for high-rise buildings. Fans are mostly installed in the basement of the building, and the basement is often not well ventilated due to limited conditions. The existing The fan control circuit only considers the exhaust air in the event of a fire and does not take into account the normal ventilation. The usual ventilation requires an additional exhaust fan, so the utilization rate of the fan is not fully utilized, which increases the cost of the enterprise. Contents of the invention [0003] The purpose of the present invention is to provide a fan control circuit, which can solve the problems of low fan utilization rate and high enterprise cost in th...
