Schneider dual power automatic switch its working principle is based on the following points: whether its performance and structure, design is very perfect. Be regarded as a pair of low-voltage electrical power supply of unique and cutting-edge technology called automatic switch atse, is an abbreviation for automatic transfer switching equipment, atse used in emergency power distribution system, the load circuit from a power supply automatically for access to another (backup) power supply to ensure that critical load continuous, reliable operation. So atse often used in important places of electricity, its reliability is particularly important. Once the conversion failure may cause harm to one of two or less, short or important load off between the power (even brief power failure), the consequences are serious, it will not only bring economic losses (standstill of production, finance paralysis), may also cause social problems (making life and safety at risk) Schneider dual power in standby power if electricity has been called a "hot spare." Users should be so important. If backup power is delayed engine power, dual power automatic switch of course also play a role, it cuts off the mains circuit for generating self-generation ready access. Especially off the mains circuit, it is important, first, to prevent anti-self-generating power transmission grid to the city, the second is to prevent the mains sudden call, and the self-generating form of synchronization and network, leaving the two sides to trip. Dual power works of structural components Profile atse generally consists of two parts: switch body (ats) + controller. The switch body (ats) have pc level (integral) of the points and cb level (circuit breaker), dual power automatic transfer switch is good or bad key electrical (atse) depends on the quality of the switch body (ats). 1.pc level ats: one structure (three-point). It is dedicated switch dual power switch, it has a simple structure, small size, self-chain, conversion speed (within 0.2s), safe, and reliable, but need to be equipped short-circuit protection. 2.cb level ats: with overcurrent release of ats, its main contacts can be connected and used breaking short-circuit current. It is composed of two circuit breakers plus mechanical interlock, dual power switch controller works with short circuit protection of working conditions Introduction The controller is mainly used to detect the monitored power supply (two) working conditions, when the power supply has to be monitored failure (such as any one phase, voltage, loss of pressure or frequency deviation), the controller gives an operation instruction switch body is with load automatically switch from one power to another power, backup power capacity is generally only 20% to 30% of the common power capacity. Figure 1 shows a typical application circuit ats. The controller and the switch body is connected into the line side. Advantages of dual power switch works ats ats controller controller should normally non-critical load options. The controller also has two forms: one from the traditional electromagnetic relays composing; the other is a type of intelligent digital electronics products. It has good performance, tunable and high precision, high reliability and ease of use. Through the dual power automatic switch works introduced, describing its security. It will give our lives a great deal of help. Enterprise real show Yueqing Lei Chung Electric Co., production and sales of Schneider products! ! !
