Utility model content
The purpose of this utility model is to provide a kind of relay with shunt can anti-alternating magnetic field disturbing.
The relay with shunt that the utility model provides, comprise shunt, relay, the first current sampling signal line and the second current sampling signal line, described shunt is connected on the exit of described relay one side, this shunt comprises the first conducting strip, the second conducting strip and be connected to the first conducting strip and the second conducting strip between sampling resistor sheet, on the first conducting strip of both sides, described sampling resistor sheet center and the second conducting strip, punching has two the first sampling terminals towards the opposite and the second sampling terminal respectively, be provided with a through hole described sampling resistor sheet is upper, the input of the first current sampling signal line is fixedly connected on the first sampling terminal, the input of the second current sampling signal line is fixedly connected on the second sampling terminal, the output of this second current sampling signal line through after through hole with the output multiple twin of the first current sampling signal line on opposite side the first conducting strip and together with.
Described shunt is laminated structure.
Described the first sampling end and the second sampling end are also gone out respectively in the opposite direction boss by the first conducting strip and the second conducting strip from surperficial tearing notch respectively and are formed.
The input of described each current sampling signal line is fixedly connected on corresponding sampling terminal by the form of spot welding.
The two ends of described sampling resistor sheet are connected with the mode one of the second conducting strip by electron beam welding with the first conducting strip respectively.
The first described sampling end is located near on the first conducting strip of sampling resistor sheet, and described the second sampling end is located near on the second conducting strip of sampling resistor sheet.
The utility model is by carrying out design improvement to the existing relay with shunt, by adopting the mode of shunt center current signal sampling, in shunt mid point output current sampled signal, not only can prevent that alternating magnetic field mixed and disorderly in surrounding environment from producing and disturbing shunt sampled signal, can also significantly promote the metering performance index of table meter in electric energy meter application, and sampling terminal adopt different towards, the current sampling signal line making combines with another current sampling signal after passing through hole again, greatly reduced the pull power of each current sampling signal under input end relativity power, install more convenient.The utility model, for Utilities Electric Co., can reduce the risk of user's stealing more, guarantees the safety of national wealth.
