Scope STQ2Z series dual power automatic transfer switch (hereinafter referred to as ATS) There are two basic company KCM1 series circuit breaker with high self-developed sub-capacity dual power automatic switch controller, etc., applicable to the rated voltage 400V.50Hz rated current of 800A and below the high-rise buildings, hospitals, shopping malls, banks, fire, chemical, Qia gold, military facilities are not allowed off a class load, part II load dual power switch, complete the double-loop power supply system Auto power conversion, thus ensuring reliability of supply important users. This product complies with GB / T14048.11-2002IEC60947-6-1 (1998) "Automatic Transfer Switching Equipment" standard. Use of the environment: ATS dual power automatic transfer switch should be installed in non-conductive dust and corrosive, explosive, flammable gases in a dry environment, and should avoid the rain and water, the device can not be subjected to shock and vibration, which is mounted vertical ramp of not more than 5 degrees, ATS external magnetic field installation place, in any direction should not exceed 5 times the geomagnetic field. Selective example STQ2Z-100 / 4.Ⅲ-380Vin50A automatic transfer switch, thermal current 100 amps WATSG dual power switch, AC rated voltage of 380 volts, 50 amps rated current, 4-pole (3-pole + neutral pole can be off ) for electricity - oil-supply system of automatic recovery. ATS dual power switch device in detail: a, ATS conversion cabinet Introduction control components and circuit breaker is mainly composed by dual power switch price, can be manually or automatically controlled carried off power transmission. Second, the structure is simple and convenient operation, ATS dual power automatic transfer switch 1. Principle: dual power automatic transfer switch is a dual power supply system (dual power) using electromagnetic coil instantaneous conversion, switch the power supply to the load. 2. Structure: A total of three parts: ① mechanism portion: mechanical holding structure and the movable housing, the spring, the movable plate, two groups of electromagnetic coil and the core, micro-control switch, control circuit and the like. ② contact parts: the movable contact, a fixed contact Shanghai People's dual power switch, terminal materials, can be curved wire, metal support, contact springs, interrupter device, insulation materials and other accessories. ③ auxiliary parts: the auxiliary contacts, insulation outside the box, manual operating rod (detachable) and other components. Three, ATS dual power switch device has the following advantages: 1) reduce the shock grid voltage and earth leakage currents, electric shock is reduced to a minimum the risk of personal; 2) use of an isolation transformer after the grounding system to prevent leakage flows into Some circuits to connect with the patient's medical electrical equipment; internal 3) power supply system once the first earth leakage fault occurs, does not cause the circuit breaker or fuse action, thus ensuring the reliability of power supply. 4) reduce the leakage current to ground, thereby enhancing the fire safety. Because healthcare IT systems with the above advantages, they have been widely adopted around the world, become the standard power system operating room and other medical establishments.
