Abstract
The utility model discloses a remote split-type multi-channel electrical fire monitoring detector, which comprises residual current transformers and a detector which is signal-connected with the residual current transformers, wherein the detector is a multi-channel detection, the number of the residual current transformers corresponds to the number of the channels of the multi-channel detector and each residual current transformer is connected with the multi-channel detector through a connection cable for signal transmission. The remote split-type multi-channel electrical fire monitoring detector has the advantages of high detector utilization rate and low cost.
Description
Technical field
The utility model relates to a kind of sniffer, specifically is meant a kind of detector for electric fire protection of remote split type multichannel.
Background technology
Detector for electric fire protection also is residual electricity streaming fire detector, is used for surveying the leakage current size of electric wiring, measures the possibility that fire takes place.So-called electric leakage, the some places that are exactly circuit are because certain reason (natural cause or artificial origin, as expose to wind and rain, humidity, high temperature, bruising, scratch, rub, corrosion etc.) insulation of electric wire or the insulating capacity of timbering material are descended, cause between electric wire and the electric wire between (insulation by damaging, support etc.), lead and the earth (reinforcing bar of electric wire by the cement wall, sheet tin etc.) some electric current to pass through, this phenomenon is leaked electricity exactly.When electric leakage took place, the electric current of sewing during as the bigger position of resistance, can produce localized hyperthermia in flowing into the earth way, cause near combustible to catch fire, thereby cause fire.In addition, the electric leakage spark in that leakage produces equally also can cause fire.
Its structure of detector for electric fire protection generally comprises residual current transformer and the detector that mutual signal connects, wherein residual current transformer is used to detect leakage current, detector then is used for signal data is carried out analysis and judgement, need to judge whether warning.At present, install and have now in the fire-fighting rectification of building at new building fire fighting device, all need to install detector for electric fire protection, but in the existing detector for electric fire protection detector general be installed together to monitor with a residual current transformer survey a power distribution cabinet, the detector for electric fire protection of single power distribution cabinet set up the cost height.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and the detector for electric fire protection of the low remote split type multichannel of a kind of cost of layout is provided.
For achieving the above object, the technical solution of the utility model is to include the residual current transformer and the detector that is connected with the residual current transformer signal that is used to detect leakage current, described detector is the multiplexed detection device, the quantity of described residual current transformer is corresponding with the way of multiplexed detection device, and connects by the transmission of connection cable signal between each residual current transformer and the multiplexed detection device.By this setting, the multiplexed detection device also carries out the distant signal control linkage to a plurality of residual current transformers simultaneously by connection cable, and so, multiplexed detection device can be simultaneously and be a plurality of with electric units (for example power distribution cabinet) to surveying at a distance, thereby the saving detector quantity reduces cost.
Further being provided with is that described connection cable length is 1m-300m.By this setting, make things convenient for the connection cable wiring.
The utility model has the advantages that detector utilization factor height, cost are low.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
