220 v and 380 v electric heating tube wiring principle diagram method of time: 2019 - 05 - 29 viewed: zero

Beijing instrument huashi free for you to provide professional quality technical services. Electric heating tube is often used to heat air, oil, water, chemical medium, hot-pressing moulds, molten salt, alkali and low melting point alloy, etc. 220 v and 380 v electric heat pipe connection schematic diagram solution by the answer. In daily industrial equipment, electrical heating tube is commonly used in the power source is 220 v and 380 v ac voltage. In 380 v three-phase four-wire system the power cord, the voltage between any two wire is 380 v, any a piece of wire can be formed between zero to 220 volts. The following figure shows three different connection modes, is composed of three u-shaped double side heating tube. 220 v heating tube can be connected to the voltage (220 v or 380 v It must be the same three specifications of the even heating tube) 。 1. When connected to 220 volts, several heating tube can be parallel or series. Calculation shows that parallel current will be bigger. According to the P = U * 1, power will be bigger, this can be the concrete calculation. ( As shown in the figure below) 2. When the voltage of 380 v, only the star connection to electricity, because the star connection line voltage = root symbol phase voltage 3 times, three natural root at the ends of the heating tube voltage is 220 v ( Note: triangle connection easy to burn out the electric heat pipe, because the line voltage phase voltage =) ( As shown in the figure below) 3. 380 v heating tube using triangle connection way connected to 380 volts. Voltage and power can play a role. ( As shown in the figure below) Single-phase 220 v power supply; Commonly used in some small devices, such as sealing machine, forming machine, etc. ； Single-phase 380 v power supply; Often used in injection molding machine, oven and other equipment; Three-phase 380 v power supply; Often used in boiler heating, mold temperature machine, heating equipment; If you have any question about the electric heat pipe, please call us!
