Since the relay relay coil KO is powered, the normally-opened contact KO is closed and the normally closed contact KOI is turned off. Because the impedance of the green signal lamp LD is much smaller than that of the anti-kick relay coil KO, Anti-trip relay contact KO: The anti-trip relay coil KO is kept in a power receiving state.

Due to the relay relay contact KO, disconnecting the closing circuit, no matter whether it is an accident or artificial opening, manual closing cannot be achieved. Similarly, when using the jump relay TWI in the comprehensive protector to replace the green signal, due to the jump position The resistance value of the relay coil of the relay relay TWI and the ZN 63 A vacuum circuit breaker in the anti-kick relay KO is unreasonable, and the electromagnetic interference is serious, so that the comprehensive protector emits continuous and different sound.

Improvement of the original design control loop According to the analysis of Figure 1, the vacuum circuit breaker wiring is unreasonable. Although the design idea is to directly monitor the state of the closing coil by the green signal lamp or the jumper relay TWI. The anti-trip relay coil KO is either held by the green signal lamp LD or the mutual electromagnetic interference of the jump relay TWI coil, so that normal loop control cannot be realized. The green signal lamp LD or jumper relay coil is separately led to a breaker normally closed auxiliary contact DL 4 in series. After the improvement, it can solve the problem and monitor the status of the breakers.

The use of a comprehensive protector integrated protector is an automatic protection component that integrates multiple functions such as protection, measurement, fault recording, and communication, and its superior performance is unmatched by conventional relay protection.

At present, it has been widely used in power supply systems and has the tendency to replace conventional relay protection. Many integrated protectors are equipped with an anti-trip relay TB J, which should make better use of the anti-trip relay TBJ on the integrated protector; at the same time, the jumper relay TWJ coil on the integrated protector does not have to bring out a circuit breaker normally closed auxiliary. Contact, can directly monitor the circuit breaker closing coil HQ, but must disconnect z N 63 A 0, improve the vacuum circuit breaker secondary circuit closing control diagram vacuum switch on the jumper circuit breaker KO coil connection.

Hand Dryer

An automatic hand dryer is a sanitary ware appliance for drying or drying hands in the bathroom. It is divided into an induction type automatic hand dryer and a manual hand dryer. The working principle of the hand dryer is generally that the sensor detects a signal (hand). This signal is controlled to turn on the heating circuit relay and the blowing circuit relay to start heating and blowing. When the signal detected by the sensor disappears, the contact is released, the heating circuit and the blowing circuit relay are disconnected, and the heating and blowing are stopped.

It overcomes the shortcomings of the wall mounted hand dryer that the air can not be discharged in multiple directions and the skin temperature of the hands is too high. It aims to provide a hand dryer that circulates the air in multiple directions. An air guiding device, the air guiding device is provided with air guiding blades, and the rotation of the air guiding device or the swinging of the air guiding blades causes the high speed hand dryer to circulate and not direct the wind.

Automatic hand dryers are advanced and ideal sanitary cleaning appliances and equipment. It is mainly used in hotels, restaurants, scientific research institutions, hospitals, public entertainment venues and the toilets of each family. After washing your hands, put your hands under the air outlet of the automatic hand dryer, the automatic hand dryer will automatically send out comfortable warm air, and quickly make your hands wet and dry, and when you leave the air outlet of the automatic hand dryer When it automatically shuts down the wind again. It can meet the requirements of not drying hands with towels and preventing cross infection of diseases.
