In view of the regulation and control effect of the transformer in the power system, technicians need to choose the appropriate transformer finishing device operation, so as to play a normal effect. Winding data is the primary problem that transformer devices need to pay attention to, and the effects of devices of different materials are different. Regarding the winding transformer, due to the special structure of the device, the device uses enameled wire, yarn-wrapped wire, wire-wrapped wire, paper-wrapped wire and other materials to cooperate, which can play a good electrical and thermal conductivity function, and the superior corrosion resistance also enhances the stability of the circuit. From the perspective of existing transformer products, the winding data in the transformer device generally includes: core data, insulation data, impregnation data, etc., and the device personnel demand is selected according to the actual situation.
(1) Iron core information. The transformer is to complete the regulation of current value and voltage value with the help of electromagnetic induction principle, and intimate is the central component of the transformer, and its material condition determines the conditioning function of the transformer. Silicon should be added to the iron sheet for the core material, so as to reduce the electrical and thermal conductivity effect of the low steel sheet and prevent the increase of energy consumption after the operation of the device. In the power industry standard, the magnetic flux density of regular silicon steel sheets needs to be controlled within the regular range, such as: the magnetic flux density of black iron sheets is 7000, and the magnetic flux density of low silicon sheets is 10000, etc., which can be selected according to the actual situation at the device site.
(2) Insulation information. In recent years, the accident rate of transformer device operation has been increasing, considering the safety and stability problem in the process of transformer installation, on-site personnel need to pay attention to the selection of insulation materials to maintain the normal operation of other equipment in the system. Nowadays, many transformers have been equipped with insulating components, such as gaskets, insulating appliances, etc., but there is still a risk due to improper human operation. The transformer device needs to enhance its insulation function from the aspects of the barrier between the coil structure layers and the barrier between the winding barriers.
(3) Impregnation materials. Impregnation treatment is the end process of winding data processing, the main intention is to improve the mechanical function, electrical function, insulation performance of the material, to prevent the later use of various incidents. After selecting the winding material, the installation personnel should paint the impregnated material and set an insulating layer on the surface of the material. The more commonly used paint material is cresol varnish, which can exert a good stability effect after brushing and prolong the service life of transformer equipment.

Precautions for the use of Delixi leakage protector
1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the operating current balance in the zero sequence current transformer and causes the leakage maintainer to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.
