PTC heater power transformer overcurrent protection PTC thermistor's known power transformer primary voltage should enter the protection state within 10 minutes, the working environment temperature of the transformer -, the temperature rises during normal operation, protection. The working voltage of the PTC heater knows that the working voltage of the transformer is 220V. Taking into account the factors of power supply fluctuations, the maximum working voltage determines the maximum current and actually measures it. When the transformer is short-circuited for the second time, the electric ball valve high temperature fan primary current sometimes takes into account the partial short circuit of the primary coil PTC The thermistor should be set close to the influence of the use environment of the transformer. When using chemical agents, potting materials or filling materials, it must be noted that the barium titanate ceramic is reduced, the PTC thermistor effect is reduced, and the heat conduction conditions caused by potting change PTC The thermistor may be damaged by partial overheating.
PTC heaters have straight-through type, direct-flow type and angle type. The cut-off electric heaters are classified according to the sealing form. The high-temperature fan has a packing-sealed cut-off electric heater and a bellows-sealed cut-off electric heater. Is the opening and closing state normal? Whether the electric heater body is damaged or leaking. Turn the normally open or normally closed electric heater door 1-2 times or do a lifting test for the normally open or normally closed electric heater. Door electric heater rod lubrication inspection and debugging The advantages and disadvantages and precautions of the power head of the door power head and the electrical system of the fluorine cut-off electric heater and the precautions Advantages The fluorine cut-off electric heater has the following advantages: small working stroke, opening and closing short time. Good sealing performance, small friction between the sealing surfaces, and long life. The shortcomings of the fluorine-lined cut-off electric heater are as follows: the fluid resistance is large, and the force required for opening and closing is large. It is not suitable for particles with high viscosity, easy to separate according to the flow direction of the medium, simple structure, convenient manufacturing and maintenance. The working stroke is small, and the opening and closing time is short. Good sealing performance, small friction between the sealing surfaces, and long life.
PTC heater uses U-shaped wave-shaped radiator to improve the heat dissipation rate of its heat pipe, and combines the advantages of viscose and pedal type. PTC electric heater has temperature control and hotness, no open flame, and high heat conversion rate. , The incomparable advantages of traditional hot components such as the operating voltage of the switching power supply are small, and the nature has a long life. When the average outdoor temperature is as low as -10 degrees Celsius, the server can only cause 60% of the energy. The high temperature fan plus the server defrosting When the server can only use 50% of the energy, the energy produced by the air conditioner in the home does not meet the heat generation required by the house. In order to fill the heat, it is necessary to basically upgrade the electric auxiliary tool electric heater in the original heating equipment And taking into account the various thermal and electrical conditions of ptc hot parts during work, its combination is strong, heat transfer, heat pipe heat dissipation characteristics are excellent, high rate, and reliable. In the winter, when the air conditioner is in heating operation in the home, the high rate of the server is slowly reduced along with the reduction of the office environment of the outdoor unit.
