A: The main functions of the transformer are: ① used to insulate the secondary equipment such as instruments and relays from the main circuit. ② It is used to expand the application range of instruments, electrical appliances and other secondary equipment. Voltage transformer installation: ① pay attention to the secondary side do not short circuit. ② One end of the secondary side must be grounded. ③ Pay attention to the installation of the terminal polarity current transformer: ① Do not open the secondary side. ② One end of the secondary side must be grounded. ③ Pay attention to terminal polarity

Good gas performance, low partial discharge value: in the transformer insulation structure, how many local insulation weaknesses, it will first occur under the action of the electric field discharge, but not immediately the formation of the entire insulation penetration breakdown, it may occur on the surface of the insulator or internal, that is, partial discharge.

The design of switching power transformer is divided into three aspects: reduce the loss of switching transformer as far as possible; Minimize leakage of switching transformer; Try to suppress the audio noise of the switching transformer.

Telecom Transformer products are widely used in cable modem, network card, hub, xDSL broadband communication equipment, switch, optical transceiver, router, embedded system, VoIP and other network communication equipment, data communication equipment, photoelectric transmission equipment, access network equipment, power line Internet equipment, voice equipment, etc

The audio transformer can realize voltage-converter conversion just like the power transformer, and can also realize audio signal coupling. There are four main functions of audio transformer:Output transformer: used in audio equipment and playback equipment, impedance conversion in the circuit.

Isolation transformer belongs to the safety power supply, generally used for machine repair, maintenance, protection, lightning protection, filtering function. The principle of isolation transformer is the same as that of ordinary transformer. They all use the principle of electromagnetic induction. Isolation transformers generally (but not all) refer to 1:1 transformers.

the structure of the power transformer:(1) Rectifier；(2) Filter；(3) Inverter；(4) Power factor correction:

The accuracy is unchanged for a long time, and there is no need to run the school, no installation and transportation, etc.

1) Trademark 2) The name and model of the electric energy meter (such as a single -phase fee control intelligent power meter). 3) Measurement License (CMC) Electric energy meters are used for measurement and settlement. It must have a measurement of measurement products issued by the National Technical Supervision Bureau to be legally produced.

The current transformer is flexible in the secondary time. You can also use soft cables to plug a pins. It can be installed with a fixed lead.
