Multisensor combination formula electric fire control detector

The utility model provides a be applicable to low -voltage distribution TT, the multisensor combination formula electric fire control detector of TN system, it comprises CPU module, panel module, power module. CPU module integration signal conditioning, analog -to -digital conversion, open and go into to leave, to communicate, to fall electric data storage and alarm instruction function, link to each other with power module, panel module. The utility model discloses the manifold occasion of sensor -based kind distribution and developing, the arbitrary combination configuration of residual current sensor channel and temperature sensor channel quantity can be carried out as required in the access of no. 4 sensors of the biggest support, has realized the configuration that stand alone type and non -independent formula multisensor made up formula electric fire detector. The utility model has the advantages of small, simple to operate, the configuration is nimble, measurement accuracy is high. 本实用新型提供了种适用于低压配电TT、T
