Dual power automatic transfer switch inductive loads affect us all know the motor load is a typical inductive load, the following example to illustrate an electric motor. Practical engineering common to such a situation, a large electric motor powered off, and then restore power within a very short period of time, and the motor is not likely to occur simultaneously in both cases. While the motor is also an initiative of the load, it can be stored magnetic energy. For an operation of the motor suddenly lost power, electric cutting magnetic field lines, can be regarded as a dual power generator means for generating a voltage - self-excitation voltage. Gradually slowed down as the rotor rotates, the self-excited voltage drops initial value (380v) when 37% of the time taken to become a time constant. The time constant large motors generally 4-5s, 5 times the time constant is the same as when the power converter. Since the motor resistance is Shanghai dual power system will not change when the voltage rises to 2 times the rated voltage, the current will rise to 2 times the rated current. Because the flow is 6-8 times the operating current, so the moment of contact ATSE contacts conversion, added to the current motor rated current of 12-16 times, 10-12 times the starting current bear CB-level dual power supply units, Unable to withstand the impact of motor power conversion brought about 12 times higher than the rated current. If an increase in the starting current of the motor which is often caused by severe mechanical damage Why power conversion. There are many practical engineering motor load must also be powered by a dual power supply, such as: fire pumps, life pumps, air conditioning, elevators, ventilation fans. And since you can consider two methods: ATSE First use with delay conversion function. Delay conversion meant here: ATSE moving contact all the way to leave power, when stopped in the middle of a position (at least after a time constant), then the power is turned the other way. This is a negative approach, contrary to the introduction of standby power is to make the load as much as possible without power purposes. And different motors, two-way power supply delay time is not easy to determine. ATSE to solve this problem arising, must be able to adjust the delay time. Another solution is the same phase switching. MTR distribution sites use dual power automatic transfer switch must have the technical elements within those additional subway load distribution sites using similar mixed load Wenzhou dual power supply units, and therefore should be used in AC-33A or B, switching power supply for should belong to frequent operation of the device, and its use should be clearly category AC-33A. In the subway station for electrical equipment, we will apply to the use of AC-33A type load of ATS. Engineering process, we have to ensure system reliability, the use of the end of the switching power supply mode, namely the ATS installed in the front-end load, installed on-site load distribution box. Our very reliable guarantee that each critical load is a dual power supply. Thus, in the future we run overhaul and maintenance of equipment to bring great convenience, a power outage or if the load failure will not affect the operation of the system. With PC-class better than CB class ATS ATS. CB class ATS installation of the current release, so in the case of high current level of ATS CB tripping to occur, the load will be lost power, while in the field of the protection of the whole timing and circuit breakers have a higher level of were fit to give us practical operation trouble. With PC-class ATS such a good solution to convert separate circuit protection and that the circuit breaker as a protective components to achieve its protective function, ATS switch as the supply and distribution components to achieve its reliable power supply function, Such products with truly safe and stable operation of the load to provide a guarantee.
