Integrated integrating current type module

Abstract

The invention relates to an integrated integrating current type module. The integrated integrating current type module comprises a three-path current sampling module, a current integrating unit, a signal processing unit and a communication module, wherein the three-path current sampling module is used for respectively sampling A, B and C-phase currents and transmitting the sampling current to the current integrating unit, integrating processing on the real-time current is carried out by the current integrating unit, the integrating current information after processing is transmitted to the signal processing unit, the integrating current information is uploaded to a monitoring terminal through the communication module, and integrating processing comprises steps that in a three-phase load balance automatic adjustment period, integer multiples of five minutes are taken as one period, a present instantaneous current value is read one time for each second, and the current values are added to a current accumulator register. The integrated integrating current type module is advantaged in that on the condition that a high precision electronic residual current breaker for balance adjustment can not be replaced, the integrated integrating current type module is employed to add to a power distribution network branch circuit in courts for acquiring the phase wire current information on the branch circuit in courts.

Description

technical field [0001] The invention relates to a current type integrated module, in particular to an integral current type integrated module. Background technique [0002] The existing three-phase load balance automatic adjustment system on the market is based on the main circuit of the distribution network in the station area, and the main circuit of the station area is collected by the host itself or collected by the terminal of the station area from the watt-hour meter on the main circuit. The phase line current information is used as the basis for adjusting the three-phase load balance. This acquisition method is not enough to adjust the three-phase load balance of the distribution network with more than two outputs. The main circuit is balanced, but the branch roads are not necessarily balanced. The phase line current information is collected on the branch road. If the branch circuit phase current information is collected from the electronic residual current circuit ...
