WATSNB-160 / 3P born Schneider million high dual power of an intelligent Schneider million high dual power with the progress of science and technology and the birth of, efficient, safe electrical appliances, all kinds such as hospitals, steel mills, banks, ports, and so on requires increasingly high reliability of power supply, and now a lot of places are still manually operated bidirectional isolation switch switching operation, often due to misuse and accidents. Therefore, advanced dual power automatic switch equipment necessary to apply to all the important occasions in the power supply system. Schneider electrical components as well-known companies around the world, we need to assume our responsibility to mankind with good power, so we will do our best to make the world's people enjoy electricity. WATSNB-160 / 3P Schneider million high dual power classification and definition of dual power are divided into PC-class dual power (integral) and CB-level dual power supply (double breaker type) PC-class dual power: the ability to access, load, but do not in breaking short-circuit current dual power dual power if you choose does not have overcurrent release load switch as the actuator belongs to PC-level automatically switch. Do not have protection, but have a higher tolerance and making capacity, to ensure the safety of the switch itself, not because of overload or short circuit fault and damage, in this case to ensure a reliable circuit switched. CB-level dual power: with overcurrent release of dual power, which can be turned on and the main contact for breaking short-circuit current of dual power if you choose over-current tripping circuit-breakers as actuators belong to CB-level automatic conversion switch. With selective protection function, short-circuit and overload protection for the lower end of the load and cable; its making and breaking capacity is much greater than the use of contactors and relays, and other components. WATSNB-160 / 3P Schneider million high dual power parameters characteristic framework nominal current (A) 63A 1,2,4,6,10,16,20,25,32,40,50,63 100A 16,25,32, 40,50,63,80,100 160A 16,25,32,40,50,63,80,100,125,160 250A 16,25,32,40,50,63,80,100,125,160, 200,250 400A electronic trip unit can be adjusted 48 points, 0.4-1 x 400 630A electronic trip unit can be adjusted 48 points, 0.4-1 x 400 1, mechanical interlock, reliable, two-way simultaneous closure will not happen . 2, the detection function, with phase, over voltage, under voltage and power frequency generator set (optional) detection, because the use of logic CPU control, with high precision, wide range of features parameter adjustment. 3, has a good electromagnetic compatibility, the country through the first test. 4, the switch body has a good electrical isolation, can provide accessibility and unloading the load. 5, four-pole switch with N-pole-before-break operation features. 6, with a padlock function lock to zero, in order to prevent misuse. 7, can be linked with the fire protection system, automatic removal of non-fire load through remote zeroing, to prevent electrical fires. Can be equipped with a variety of hardware interface boards support a variety of fieldbus protocols. 8, products for the mechanical and electrical integration structure, complete structure, small size, easy installation. 9, two-way power can be set as common or backup power. 10, to ensure reliable operation within switching power supply of the motor drive control automatically chooses the two sources that meet the quality requirements of a phase. 11, has three switch positions. 12, it has three operation mode, i.e. manual, automatic, electric. 1.3 series; 2, 3, Level 4 WATSNB-160 / 3P Schneider million high dual power rules 1, when a power outage for any reason, and in a relatively short time when the power supply can not be restored, you must enable standby power. Step: 1.1 removal Mains each breaker (including power distribution control room cabinet each breaker, dual power switching power supply circuit breaker box City), anti-pull double-throw switch to self-powered send down one side, holding dual power switch box-owned electric circuit breaker in the off state. 1.2 Start standby power (), standby group is operating normally, the sequence generator breaker is closed, self-powered control cabinet for each circuit breaker. 1.3-by power supply switching box closed each backup power circuit breakers, each load transmission. ④ standby power during operation, the operator on duty shall not leave the generator, and adjust the voltage, frequency and other plant according to load changes, abnormal timely manner. 2, when the mains power is restored, power conversion should work in a timely manner, cut off standby power, restore electricity supply. Step: 2.1 self-powered off sequentially, each circuit breaker, the order is: dual power switching box-owned power circuit breaker →-owned power distribution cabinet generator master switch for each circuit breaker → → will double throw switch to City electricity supply side. 2.2 Engine shutdown procedure press stop. 3.3 in order, from the mains power supply to the main switch is closed each one by each branch circuit breaker switch, dual power switching box from the mains supply breaker to the closed position.
