Abstract
The utility model relates to the device that a kind of fire alarm system controls draft fan, it comprises fan control module, relay, contactor and the cable for connecting, during breaking out of fire, fire alarm system sends signal to fan control module, fan control module order relay works, the normally closed auxiliary contact of relay is opened, and the contactor in control loop is disconnected, thus makes draft fan out of service.
Description
Technical field:
The utility model relates to the device that a kind of fire alarm system controls draft fan.
Background technique:
When a fire, draft fan is rotated further, and will certainly strengthen developing fire, therefore needs to close draft fan in the very first time.When occurring for fire at present, the scheme of excision blower fan is such: when a fire, draft fan still rotates, by manually carrying out the blower fan excising scene of fire after the electric substation operator on duty having people on duty receives fire alarm signal.Issue a signal to cut-out fan power from warning device and approximately need 3 ~ 5 minutes.In addition, manually close down the start-stop button be arranged on outside each room wall and will certainly cause temporal delay and the injury to the person.And, then cannot pass through manual control at unattended substation, therefore more need increase draft fan and Fire alarm control unit to link, by fire alarming and control device automatic start-stop draft fan.
Model utility content:
The utility model provides a kind of fire alarm system to control the device of draft fan, it comprises fan control module, relay, contactor and the cable for connecting, 1 group of normally closed auxiliary contact of wherein said relay is as a switch, be serially connected in the control loop of draft fan, often open the inverse signal of auxiliary contact as fan control module for 1 group of described relay, described contactor is arranged in described control loop; During breaking out of fire, fire alarm system sends signal to fan control module, relay work described in fan control module order, and the described normally closed auxiliary contact of described relay is opened, described contactor in described control loop is disconnected, thus makes draft fan out of service.Shut-in time to draft fan when shortening breaking out of fire thus, improve sensitivity, avoid the damage to equipment and the person.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The utility model provides a kind of fire alarm system to control the device of draft fan D, it comprises fan control module (5), relay 1ZJ, contactor C and the cable for connecting, 1 group of normally closed auxiliary contact of wherein said relay 1ZJ is as a switch, be serially connected in the control loop of draft fan D, often open the inverse signal of auxiliary contact as fan control module (5) for 1 group of described relay 1ZJ, described contactor C is arranged in described control loop, as shown in Figure 1.
When a fire, the sense of two or more cigarette or temperature detector are reported to the police, after Fire alarm control unit receives fire alarm information, lower photos and sending messages gives each control module signal, wherein fan control module (5) drives draft fan to close, and receive its inverse signal, monitor its running state.
Fan control module (5) can not directly act on draft fan D, (24V power supply is from Fire alarm control unit to need to install a 24V direct current auxiliary reclay 1ZJ additional, connected by cable), using 1 group of normally closed auxiliary contact (1) of this relay 1ZJ as a switch, be serially connected in the control loop of draft fan, more often open the inverse signal of auxiliary contact (2) as Fire alarm control unit fan control module (5) using 1 group of this relay 1ZJ.Switch knob HA, 1HA press rear involution, and contactor C is in hold mode, and draft fan D is in running state.When a fire, Fire alarm control unit sends signal fan control module (5), fan control module (5) order relay 1ZJ action, relay 1ZJ live line work, normally closed auxiliary contact (1) is opened, contactor C dead electricity in this control loop, the auxiliary contact (3) of contactor C disconnect, and draft fan D is out of service.Meanwhile, the auxiliary contact (4) of contactor C disconnect, and tutorial light HD extinguishes.Often open auxiliary contact (2) to close, send the fan control module (5) of blower fan stoppage in transit signal to the Fire alarm control unit of MCR Master Control Room, pass on running state.When fire alarm is removed, fan control module (5) order relay 1ZJ action, relay 1ZJ live line work, normally closed auxiliary contact (1) closes, contactor C in this control loop is charged, and the auxiliary contact (3) of contactor C close, draft fan D startup optimization, the auxiliary contact (4) of contactor C close simultaneously, and instruction HD lamp is bright.The auxiliary contact (2) of often opening of relay 1ZJ is opened, the blower fan stoppage in transit blackout of the fan control module (5) of Fire alarm control unit.
Each series connection fus 3RD, 4RD in the power positive cathode loop of 24V direct current auxiliary reclay 1ZJ, as the protective device of relay 1ZJ.
Claims (4)
1. the device of a fire alarm system control draft fan, it comprises fan control module, relay, contactor and the cable for connecting, 1 group of normally closed auxiliary contact of wherein said relay is as a switch, be serially connected in the control loop of draft fan, often open the inverse signal of auxiliary contact as fan control module for 1 group of described relay, described contactor is arranged in described control loop; During breaking out of fire, fire alarm system sends signal to fan control module, relay work described in fan control module order, and the described normally closed auxiliary contact of described relay is opened, described contactor in described control loop is disconnected, thus makes draft fan out of service.
2. a kind of fire alarm system as claimed in claim 1 controls the device of draft fan, and wherein said relay is 24V direct current auxiliary reclay.
3. a kind of fire alarm system as claimed in claim 1 controls the device of draft fan, is in series with fus in the power positive cathode loop of wherein said relay.
4. a kind of fire alarm system as claimed in claim 1 controls the device of draft fan, and wherein said fire alarm system has the sense of two or more cigarette or temperature detector.
