Product symbols are incomplete or not standard:The label should include one of the fundamental methods of correctly installing and correctly guiding the user's vital information to indicate the symbol of the product to ensure the safety of the user and the property. Used, eye-catching, labeling need

Non-standard power plug:Our regular home single-phase power plugs are extremely grounded and pole-to-ground both ways and the use of the power plugs should be such as to avoid unipolar prodding, ie when a latch plug socket is plugged in with a co-operating other bolt Is not accessible. Check that th

Technical Features of Large Aluminum Electrolytic Capacitors for Inverter Air Conditioners According to the current requirements of domestic inverter air conditioner manufacturers and similar foreign products, inverter air conditioner with large aluminum electrolytic capacitors for the technical fe

Single-phase motor generally refers to single-phase asynchronous motor powered by single-phase AC power supply (AC220V). The choice of capacitor for single-phase motor is related to the design of motor data. Some single-phase motors with small power can be operated with a single capacitor. Single-ph

CBB capacitor with metallized polypropylene film series structure type, can resist high voltage, large current shock, with a low loss, excellent electrical performance, high reliability and self-healing performance. Use of CBB capacitors: Awidely used in instruments, instruments, television sets and

Starting capacitance capacity:C=350000*I/2p*f*U*cosφIn the formula: I---current-frequency; U--voltage ;2p---power factor 2, small power factor 4 ;cos φ ---power factor (0.4-0.8). Starting capacitor voltage: capacitor voltage is greater than or equal to 1. 42*U. Operating capacitance capacity:C=1200

In general, in single-phase capacitor starter motor, the capacitor capacity in series in the starting winding increases by 1 time, the starting torque can only be increased by 50%, and the starting current is increased by 200%. In single-phase capacitive motor, the efficiency of the motor will be re

The capacitor is a container in which charges are stored. It is composed of two pieces of metal close to each other, separated by insulating material, depending on the insulating material. Can be made into a variety of capacitors, such as: mica, porcelain dielectric, paper dielectric, electrolyt

A fine-tuned capacitor, also called a semi-adjustable capacitor, has a capacity of between 5 and 45 PF. There are many kinds of them, and the following is common:1) Porcelain capacitor with fine-tuning: it is characterised by wear resistance and long service life. 2) Tube-type fine tuning capacitors

Capacitive reactance of capacitors.Capacitors have special resistance to AC, called capacitive reactance. Capacitive reactance can be calculated by the following formula, the larger the capacitor capacity, the higher the frequency of the current, the smaller the capacitive reactance is, and the easi
