Description
Technical field
The utility model relates to a kind of detector.Specifically, the multiloop fire detecting arrangement detecting the electrical fire caused because of faults such as short circuit, overload, three-phase imbalance, ground connection is used to.Be applicable in low-voltage power supply system.
Background technology
All know in electric system, often there will be the electrical fire accident caused because of faults such as short circuit, overload, three-phase imbalance, ground connection in low-voltage power supply system, great threat is constituted to national economy and people's lives and properties.For the loss that reduction brings national economy and people's lives and properties due to electrical fire accident, method in the past relies on the tripping operation of isolating switch or fuse to carry out prevention and control, but the problems such as this Control Technology exists trip action definite value and the time affects greatly by environmental change, poor reliability, make to be difficult in actual applications play useful effect.The electrical fire of existing detection residual current supplements Control Technology, carry out electrical fire detection based on the lump amplitude Characteristics of residual current, be difficult to accurately differentiate be evenly distributed residual current (normally running) and put heat and gather residual current (fault), therefore, often occur failing to report, wrong report situation.
Utility model content
Problem to be solved in the utility model is to provide a kind of multiloop fire detecting arrangement.This multiloop fire detecting arrangement, good reliability.Adopt this sniffer to carry out electrical fire detection, can avoid failing to report, wrong report situation occurs.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Multiloop fire detecting arrangement of the present utility model comprises electric wiring A, is characterized in also comprising fire control device XF.Described electric wiring A is no less than two-way, described in be no less than between the electric wiring A end of incoming cables of two-way and leading-out terminal and be connected with isolating switch HD and residual current detector TC all successively, residual current detector TC is all connected with fire control device XF by wire.
As can be seen from the above scheme, because the utility model contains fire control device.Described electric wiring is no less than two-way, described in be no less than between the electric wiring end of incoming cables of two-way and leading-out terminal and be connected with isolating switch and residual current detector all successively, residual current detector is all connected with fire control device by wire.Utilize a fire control device, continuous accurate instantaneous detection can be carried out to the residual current in multiple loops more than two-way simultaneously, and then realize effectively preventing the electrical fire that multiple loop causes because of faults such as short circuit, overload, three-phase imbalance, ground connection and isolating, not only good reliability, and avoid the generation of failing to report, reporting by mistake situation.
Accompanying drawing explanation
Fig. 1 is multiloop fire detecting arrangement principle schematic of the present utility model.
Embodiment
As shown in Figure 1, multiloop fire detecting arrangement of the present utility model comprises electric wiring A and fire control device XF, described electric wiring A has six tunnels, be connected with isolating switch HD and residual current detector TC between the end of incoming cables of six road electric wiring A and leading-out terminal all successively, residual current detector TC is all connected with described fire control device XF by wire.
Wherein, described residual current detector TC is HV20020-XF-TC type residual current detector, and described fire control device XF is HV2002D-02 type fire control device.
The utility model utilizes a fire control device, continuous accurate instantaneous detection can be carried out to the residual current in six loops simultaneously, and then realize effectively preventing the electrical fire that six loops cause because of faults such as short circuit, overload, three-phase imbalance, ground connection and isolating.
