Abstract
The invention relates to a fire-fighting linkage draught fan power distribution box provided with a shunt release and used for a substation. The fire-fighting linkage draught fan power distribution box is mainly used for supplying power to an indoor ventilation fan and controlling the indoor ventilation fan. A main electrical circuit of the fire-fighting linkage draught fan power distribution box comprises a primary control circuit and a secondary control circuit. The primary control circuit is provided with a breaker QF, the shunt release MX, a normally-open contact of a contactor KM1 and a normally-open contact of a contactor KM2, wherein the breaker QF, the shunt release MX, the normally-open contact of the contactor KM1 and the normally-open contact of the contactor KM2 are connected in sequence; the two ends of the contactor KM1 are connected with the ventilation fan M and the shunt release MX respectively. The secondary control circuit is provided with a manual switch K, a coil of the shunt release MX, a temperature controller KH, the contactor KM1, the contactor KM2, a fuse FU1 and a fuse FU2. In an automatic control state, the ventilation fan is automatically powered on to start working when the indoor temperature exceeds a limiting value (35 DEG C); when the indoor temperature is lower than the limiting value or the temperature controller breaks down, the ventilation fan can be manually controlled to start. Meanwhile, a fire warning system signal contact (switched on when a fire happens) can be connected into the control circuits in series to achieve linkage of the ventilation fan and a fire fighting system, and then the fire-fighting requirements can be met.
Description
Technical field
The present invention relates to electric substation's band shunt release fire-fighting linkage blower fan distribution box, the electricity supply and control being mainly used in indoor ventilation fan uses.
Background technique
Generally draft fan (the general <3kW of every Fans power) is all provided with in the building such as switchgear room, control room of current electric substation.In engineering reality, because of outdoor environment temperature and equipment work heat radiation factor, room temperature easily exceedes the requirement of equipment normal working temperature.Therefore, conservative control draft fan works, and reduce operation expense, and the required value meeting draft fan and fire-fighting link must be inquired into.
Summary of the invention
For solving above technical problem, the present invention proposes electric substation's band shunt release fire-fighting linkage blower fan distribution box, and this distribution box energy conservative control draft fan works, and reduces operation expense, and meets draft fan and fire-fighting link.
For realizing above goal of the invention, the present invention proposes a kind of technological scheme: electric substation's band shunt release fire-fighting linkage blower fan distribution box, its main body electric loop comprises a control loop, secondary control loop, a described control loop is provided with the circuit breaker Q F connected successively, shunt release MX and contactor KM1, contactor KM2 normal opened contact, contactor KM1 two ends respectively with draft fan M, shunt release MX connects, secondary control loop is provided with hand switch K, shunt release MX coil, temp controller KH, contactor KM1, contactor KM2, fus FU1 and fus FU2, temp controller KH two ends are connected to Ac respectively by fus, after temp controller KH output contact is in parallel with hand switch K, the circuit that forms of series contactor KM1 coil is in parallel with temp controller KH again, contactor KM2 normal opened contact is in parallel with temp controller KH with after shunt release MX coils connected in series, contactor KM2 coils connected in series is in fire alarm circuit.
The present invention is used for draft fan electricity supply and control in the building such as substation control buildings, control room, adopts and automatically control when draft fan is normal.During automatic control, when room temperature exceedes limit value (35 DEG C), draft fan automatically switches on power and starts working.When room temperature lower than or temp controller fault time, can Non-follow control draft fan start.Meanwhile, realizing the interlock of draft fan and fire-fighting system by being connected in series fire alarm system signal contact (closing when fire occurs) in control loop, can fire-fighting requirements be met.
Accompanying drawing explanation
Fig. 1 is the electrical wiring schematic diagram of an embodiment of the present invention control loop;
Fig. 2 is the essential electrical elementary diagram of embodiment of the present invention secondary control loop;
Fig. 3 is the electrical wiring schematic diagram of embodiment of the present invention fire alarm circuit.
Embodiment
Referring to accompanying drawing 1-Fig. 3, embodiment of the present invention electric substation band shunt release fire-fighting linkage blower fan distribution box, its main body electric loop comprises a control loop, secondary control loop, a described control loop is provided with the circuit breaker Q F connected successively, shunt release MX and contactor KM1, contactor KM2 normal opened contact, contactor KM1 two ends respectively with draft fan M, shunt release MX connects, secondary control loop is provided with hand switch K, shunt release MX coil, temp controller KH, contactor KM1, contactor KM2, fus FU1 and fus FU2, temp controller KH two ends are connected to Ac respectively by fus, after temp controller KH output contact is in parallel with hand switch K, the circuit that forms of series contactor KM1 coil is in parallel with temp controller KH again, contactor KM2 normal opened contact is in parallel with temp controller KH with after shunt release MX coils connected in series, contactor KM2 coils connected in series is in fire alarm circuit.
Circuit breaker is generally closed state, and the main protections such as the short circuit current protection of current supply circuit are realized by circuit breaker, and contactor is only as the use of the control loop of switch.Under normal working, hand switch K is in off state, breaker closing, and fire alarm system signal contact disconnects, and contactor KM2 coil blackout, its normal opened contact is in off state, shunt release MX coil blackout.Now, by the folding of temp controller KH control loop, namely when exceeding temperature parameter (35 DEG C) that temp controller KH is arranged, temp controller KH output contact closes, and contactor KM1 wire loop switches on power, KM1 action, and each output loop is powered.Manually-operable is operating manual K switch when patrol officer patrols and examines according to actual requirement, then disconnects as required or closed each circuit breaker.When fire alarm system sends closure signal, the fire alarm system signal contact sealed in closes, contactor KM2 coil electricity, its normal opened contact closes, the circuit breaker Q F tripping operation simultaneously of shunt release MX coil electricity, the power-off of blower fan major loop, draft fan quits work.
Fire-fighting link draft fan distribution box comprises control box main body, is furnished with door lock, nameplate in casing front, and arranges a transparent window specially, and patrol officer can pass through window and checks situation in case.In addition, hand switch K is arranged at outdoor doorway, and after fire signal is removed, patrol officer can discharge fume in on-site manual unlatching, facilitates patrol officer to inspect, ensures patrol officer's personal safety.
Following content is the further description done the present invention in conjunction with concrete mode of execution, can not assert that specific embodiment of the invention is confined to these explanations.For the those of ordinary skill of the technical field belonging to the present invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
