As shown in Figure 1, fire-fighting emergent shown by the first embodiment of the utility model starts cabinet, the fire-fighting emergent is opened Dynamic cabinet includes cabinet body 1 and cabinet door 2, and an accommodating space is formed between the cabinet body 1 and cabinet door 2, is provided on the cabinet body 1 point Other the first ammeter 4 that external three-phase electricity is detected, the second ammeter 5, third ammeter 6 and voltmeter 7.The fire-fighting Emergency starting cabinet further includes the major loop and secondary control loop being arranged in the accommodating space, the input of the major loop It is connected respectively with the U phase of external three-phase electricity, V phase and W phase, the output of the major loop is connected with the power input of water pump, described Major loop and the secondary control loop are electrically connected.

Specifically, the major loop carries out controlling its on-off by secondary control loop, realization is switched on or switched off supply water The three phase mains of pump is further reached for fire-fighting fire extinguishing and provides the effect at water source；Using the first ammeter 4, the second ammeter 5, Third ammeter 6 and voltmeter 7 can observe in time fire-fighting emergent starting cabinet whether transmitting line failure, guarantee that it is normal Operation and in time maintenance.

As shown in Fig. 2, the major loop includes circuit breaker Q F, A.C. contactor KM, U phase, the V phase of the external three-phase electricity Pass through circuit breaker Q F with W phase to be connected with the A.C. contactor KM.

Specifically, being also connected with an electrothermal relay KH, the ac contactor between the A.C. contactor KM and water pump Device KM and electrothermal relay KH is also in parallel with a reactor DKQ respectively.It is also set up between the circuit breaker Q F and A.C. contactor KM There is mutual inductor TA, a control transformer is additionally provided between electrothermal relay KH and water pump.In addition, the fire-fighting emergent starts cabinet Cabinet door 2 on an operation handle 3 can also be set.The operation handle 3 is connected with circuit breaker Q F, operates after fire alarm generation The necessary authorized people's operation of handle 3, and then the control whether closed a floodgate to circuit breaker Q F realized, wherein the handle of operation handle 3 is flat Row is not close a floodgate in horizontal plane, is to close a floodgate perpendicular to horizontal plane.

In the present embodiment, the secondary control loop is additionally provided with malfunction indicator lamp 8, run indicator 9 and stops instruction Lamp 10.Specifically, the malfunction indicator lamp 8, run indicator 9 and stopping indicator light 10 are all set in fire-fighting emergent starting cabinet Cabinet body on 1.The working condition that visual in image can be understood fire-fighting emergent by above-mentioned indicator light and start cabinet.

As shown in figure 3, major loop carries out controlling its on-off by secondary control loop, realization is switched on or switched off for feed pump Three phase mains, can specifically select the mode of act including but not limited to set forth below at least any one：

Mode one, the secondary control loop include button SYB, relay K1, A.C. contactor KM, the time relay KT, relay K2 and A.C. contactor KM；One end of the button SYB by circuit breaker Q F with outside three-phase electricity it is any one Be connected, the other end of the button SYB is connect with the relay K1, the relay K1, A.C. contactor KM, the time after Electric appliance KT, relay K2 and A.C. contactor KM are sequentially connected in series.

Operate self-checking function when, in the case that circuit breaker Q F does not close a floodgate, the lower SYB button that press...withes one's finger does not unclamp, at this time after Electric appliance K1 closure, after K1 closure, former relay K1 opened point becomes close point, and the electricity of time relay KT brings into operation timing, when When reaching the set time, relay K2 closure, after relay K2 is closed, former relay K2 opened point becomes close point, contact Device KM closure, signal lamp HR are lighted, and secondary control loop self-test is completed.

Mode two, the secondary control loop include that one end of button JQB and A.C. contactor KM, the button JQB are logical It crosses circuit breaker Q F to be connected with any one of external three-phase electricity, the other end of the button JQB and one end of A.C. contactor KM Connection, another termination zero of the contactor KM.

Fire alarm such as occurs, when original fire hydrant cabinet starts unsuccessful, need to only operation handle 3 be rotated to by being authorized personnel at this time Start position both can (operation handle be in plumbness), circuit breaker Q F closes a floodgate in "on" position at this time, press...with one's finger down by Button JQB does not unclamp, and contactor KM closure realizes forced service fire pump.

Mode three, the secondary control loop include time relay KT, relay K2 and A.C. contactor KM, described One end of time relay KT is connected by circuit breaker Q F with any one of external three-phase electricity, and the time relay KT's is another One end is connected with one end of relay K2, and the other end of the relay K2 is connect with one end of A.C. contactor KM, described to connect Another termination zero of tentaculum KM.

The starting of original fire hydrant cabinet is unsuccessful, is authorized personnel at this time only and needs to rotate to operation handle 3 into starting position and (grasp Make handle and be in plumbness).After circuit breaker Q F closes a floodgate, power supply U.V.W is input to chokes reactor DKQ through circuit breaker Q F, by Biggish inverse electromotive force can be generated in chokes reactor DKQ, starting voltage is inhibited into the fire-fighting 60% or so of voltage rating Pump starts rotating operation with lesser impact, when fire-fighting revolution speed constantly rises, and fire pump electric current gradually declines, because of chokes electricity Anti- device induction reactance is basically unchanged, and chokes reactor both end voltage declines at this time, and fire-fighting pump startup voltage is stepped up to close to specified Value, fire pump start completion, operation contactor KM closure, signal lamp HR are lighted, and fire pump operates normally.

Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand：It is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type, should all cover in the claim of the utility model and the range of specification.
