Description
Technical field
Distribution box technical field is the utility model is related to, it is more specifically, more particularly to a kind of to be cut for distribution box fire-fighting
Non- trunk module.
Background technology
Substantially control the pattern of non fire fighting power supply all the way in engineering using a fire-fighting module at present.It is generally divided into two kinds
Situation：
The first is：Breaker shunt opening coil in distribution box directly can be connect DC24V active signals from DC24V
Feedback signal is provided to breaker shunt opening coil loop, then by auxiliary contacts of circuit breaker.Such case be only applicable to 63A cage with
Under low capacity switch, switch more than 63A cage is then possible to cause switch to be sent out because the control coordinated signals modular power that disappears is small
The raw phenomenon for refusing tripping operation, making to cut non-action to complete.It is also possible to directly damage and disappear because load (shunt opening coil power) is big
Anti- control module.So each complete less use of producer of such case.
It is for second：From AC220V/380V, power distribution cabinet (case) is interior to be needed to install one additional breaker shunt opening coil
Auxiliary reclay among DC24V, DC24V fire-fighting active signals are first connected to the coil of middle auxiliary reclay；Again by centre
Between the normally opened auxiliary point of relay be connected in series to breaker shunt opening coil loop, power supply mouth under breaker takes, because shunt opening coil is not
Can be long charged；Again feedback signal is returned with the auxiliary contact of breaker to fire protection control center one cut-off loop of offer.This
Most of producer is all using kind at present, makes the more powerful of shunt opening coil with low-voltage control high voltage, is easy to the de- of switch
Button.Existing way is：One fuse (protective breaker)+middle auxiliary reclay++ 5 terminals of auxiliary reclay base
Row is arranged on guide rail, and composition one is used to connect breaker and the circuit of fire protection linkage control module.
The shortcomings that existing this prescription formula mainly have it is following some：
1st, unsightly, component be uneven, cabling it is in disorder.
2nd, volume is big, and occupancy distribution box space is big, is not easy to install.
3rd, wiring bothers, and complete (strong power part) wiring is intricate, easily obscures with the control (weak current part) that disappears, and can make existing
Field light current installation personnel is ignorant of wiring or wrong line；
4th, forceful electric power and light current are not easily distinguishable, and AC220V/380V easily is introduced into fire-fighting linkage system, cause module to burn,
Influence system operation.
