1. Low-voltage circuit breakers: Low-voltage circuit breakers, also known as automatic switch, it is a kind of both the manual switch, but also automatically lose pressure, voltage, overload, and short circuit protection of electrical appliances. It can be used to distribute power, start asynchronous motors infrequently, protect power lines and motors, etc., and automatically cut off the circuit when they are severely overloaded, shorted, undervoltage, etc. Their function is equivalent to a fuse switch Overheat relay and other combinations. And in breaking the fault current generally do not need to change the parts, one has been widely used.
1) circuit breaker accessories
2) Miniature circuit breakers: Miniature circuit breakers, referred to as MCB, is the most widely used terminal protection device in building electrical terminal power distribution devices
3) Molded Case Circuit Breaker: Molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Molded case refers to the use of plastic insulation as a device housing, used to isolate the conductor and the ground metal part. Molded case circuit breakers usually contain thermal-magnetic trip units, while large-scale molded case circuit breakers are equipped with solid-state trip sensors. The company is located in:
4) Frame circuit breaker
5) intelligent universal circuit breaker
2 smart distribution:
1) Low-voltage reactive power compensation complete sets of devices
2) Compound switch
3) Operating handle
4) reactive power compensation controller
3. Low-voltage distribution switch:
1) load switch: load switch, as the name suggests is to switch off the load current, to distinguish it from the high-voltage circuit breakers, the load switch has no ability to interrupting the fault current can not be broken, only breaking the load current under normal system operation, Load switch hence the name
2) Disconnector: Disconnector is the most widely used type of high-voltage switchgear. Its working principle and structure are relatively simple. However, due to the large usage and high reliability of work, the design of substation and power plant, The impact of establishing and operating safely is greater. The main feature is no switch arc interrupter capacity, only in the absence of load current points, the circuit
3) Knife switch
4. Fuse:
Fuse is based on the current exceeds the specified value for a certain period of time, with its own heat to make the melt melt, so that the circuit is made of a principle of the current protection. Fuse is widely used in low-voltage power distribution systems and control systems and electrical equipment, as short-circuit and over-current protection, is one of the most popular protection devices. The company is located in:
Fuse is an over-current protection appliances. Mainly by the fuse fuse and fuse two parts and filler plus other components. When used, the fuses are connected in series with the circuit to be protected. When the current of the circuit to be protected exceeds the specified value and the heat generated by the melt itself blows off the melt after a certain period of time, the circuit is disconnected and protected . The company is located in:
1) melt core
2) Fuse base
3) low-voltage fuse
Transformer:
1) Electronic Transformer: Electronic transformer, the input is AC220V, the output is AC12V, the power can reach 50W. It is mainly in the high-frequency electronic ballast circuit developed on the basis of a transformer circuit, its performance is stable, small size, high power, thus overcoming the traditional silicon steel transformers large, bulky, high price shortcomings
2) control the transformer
3) Isolation Transformer: Isolation Transformer and the principle of ordinary transformer is the same. Are the use of electromagnetic induction principle. Isolation transformers generally refers to 1: 1 transformer. Because the secondary is not linked. There is no potential difference between any of the secondary wires and ground. Use safe. Commonly used for maintenance of power. Isolation transformer is not a 1: 1 transformer. Power transformers and tube devices are also isolated transformers. Such as tube amplifiers, tube radios and oscilloscopes and lathe control transformers and other power supplies are isolated transformers. Such as color TV for security maintenance commonly used 1 to 1 away from the transformer. Isolation transformer is the use of more, is also used in air conditioners.
6. Leakage protection device: to prevent electric shock accident leakage protection device can only be used as additional protection. Installation of leakage protection device shall not cancel or give up the original safety precautions.
Our company has engaged in low-voltage power distribution work for decades of engineers, professional low voltage distribution for you to solve the problem, you are welcome to come to consult!
