Abstract

The invention discloses a combined mutual inductor without fear of open-circuited secondary side, and a production method of the combined mutual inductor. The combined mutual inductor at least comprises a voltage mutual inductor and a current mutual inductor, wherein the voltage mutual inductor is connected between buses in parallel; the current mutual inductor is a current mutual inductor without fear of open-circuited secondary side, the current mutual inductor without fear of open-circuited secondary side comprises a feed-through type bus current mutual inductor and a switching current mutual inductor; the bus current mutual inductor is used for inducing bus current; an output end of the bus current mutual inductor is electrically connected to a primary coil wiring terminal of the switching current mutual inductor; the switching current mutual inductor, the bus current mutual inductor and the voltage mutual inductor are mechanically connected and electrically isolated from one another through resin poured therein. According to the combined mutual inductor, the damage caused by the open circuit of the secondary side can be fundamentally prevented and avoided effectively, and the combination of the two metering mutual inductors has advantages of high integration and installation convenience.

Description

technical field [0001] The invention relates to a combined transformer which is not afraid of open circuit at the secondary side and a manufacturing method thereof. Background technique [0002] Before new equipment is put into use, it is necessary to test the equipment in order to verify the performance of the equipment, especially the safety performance and working performance of the equipment must be guaranteed. In order to ensure the safe and economical operation of the power system, it is necessary to monitor and measure the operation of the power equipment. However, general measurement and protection devices cannot be directly connected to the primary high-voltage equipment, but need to convert the large current of the primary system into a small current in proportion to supply the measuring instruments and protection devices. [0003] In every link of the power system, including power generation, power transformation, power transmission, power distribution and power ...
