What should you check before installing the ceramic heating coil?

Inspection before installing the electric heater Before installing the motor, the following inspections should be carried out: The motor should be intact. The rotating rotor should be light, without jamming and abnormal sound; the core rotor and the journal of the motor transported in separate boxes of stators and rotors should be completely free of corrosion. The size of the current is directly related to the power, and is also related to voltage, difference, power factor (also known as power factor), etc.

Electric heating of electric ball valves refers to a resistance furnace heated by resistance. For three-phase 380V electric heating equipment, the current per KW of the frpp tube is 1.5 A. Even if the Kw number plus half (multiplied by 1.5) is the current A. The 3KW electric heater is calculated by adding half of the electricity, and the current is 4.5 A. The electric heating furnace is calculated by adding half of the electricity, and the current is 22.5 A. This formula should not refer to electric heating, but also applies to incandescent lamps. Although the lighting bulb is single-phase instead of three-phase, the three-phase four-wire lighting power supply is still three-phase. As long as the three phases of the ceramic heater are basically balanced, it can be calculated in this way. In addition, electrical appliances measured in KVA (such as transformers or rectifiers) and phase-shifting capacitors measured in KVar (used to improve power factor) also apply.

Ceramic heater leakage current IresRF/WH series polymer PTC thermistors lock in their high resistance condition, according to the current through the thermistor. At maximum working current/all normal operating current The maximum current that passes through the power circuit under all normal operating conditions.

At the ambient operating temperature of the power circuit, the holding current of the RF/WH series polymer PTC thermistor used to maintain the power circuit is generally greater than the working current. The process of the polymer/WH series polymer PTC thermistor changing from low resistance to high resistance when overcurrent occurs or the operating temperature rises. The RF coaxial connector intelligent control system adopts VFD display mode and infrared induction remote control function, with power off parameter maintenance, controller common fault reminder, manual forced operation and other functions.

The RF coaxial connector intelligent control system adopts VFD display mode and infrared induction remote control function, with power-off parameter maintenance, controller common fault reminder, manual forced operation and other functions. The time required for thermistor to operate from the beginning of overcurrent generation. According to the infrared induction of infrared radio waves, heat is immediately conducted. The real hydropower project protective heating technology avoids many aspects of power leakage problems, and sets automatic protectors such as high temperature protection, air burning protection, and cold protection.
