STQ1 series of intelligent dual power automatic transfer switch monitors the AC grid insulation 1. Function Description: ①SJY-12 two ungrounded AC system for real-time monitoring of the insulation resistance, insulation monitoring also showed two-way value; ② Press " indeed allow "button, the alarm light is on, stop output control signal; 2. Usage: ① power display, digital tube first show" 8.888 "for two seconds. Subsequent monitoring instrumentation into eight states. Digital control system gives the corresponding value of the insulation resistance. Display abnormal, press the "Reset" button (Reset Reset) dual power switch price, the instrument again displays "8.888" for two seconds backward eight monitoring state. ② alarm set for each power grid system insulation alarm is automatically set to the value of 0.010 meg of memory. To set a new alarm dual power, you should do the following: Press the "Settings" button (set I Set I) CDQ7-800 / 3 dual power supplies, digital display has been set to the value immediately. Then each time you press the button, the setting value increases one. If you press and hold the button down, the set value is continuously increased progressively, again began to increase by more than 9.000 0.000 meg meg later. By setting value after release the button, the setting value continues to be displayed for two seconds, then automatically return to the monitoring state. ③ alarm acknowledgment when the insulation resistance is lower than the set value, the "alarm" red light flashes, external alarm relay, directly connected to an external alarm. Press the "OK" button (confirm Ack.), Silencer, red light stops blinking and stays on. When the insulation resistance to be restored to the set value or more, the red light goes off. ④ self-test (test light) Press the "self-test" button (Self-Test Test), internal program gives digital display "8.888", all lights full on, the alarm relay is closed. Release the button to restore the original state. How to have dual power switch automatically converted power monitoring and control equipment? Dual power switch professional manufacturer of Thai Industries Shanghai only to implement the "first extraction, monitoring and control, to the wind production quotas" 12-character principle and the "reliable ventilation, drainage standards, monitoring and effective management in place" Transmission work system, to take on the tunneling face ventilation equipment supply dual power supply, and resolutely implement the heading face double fan, dual power automatic transfer, to ensure continuity of supply air Heading Face achieve a tunneling face "three special two Block "and double fan, dual power supply ventilation in to eliminate" achieved remarkable results on one through three defenses "accident. Field practice is attached to each of the tunneling face twice the power supply must be guaranteed, including a dedicated power supply fan-based, face equipment and monitoring sub-station power supply as deputy vice-powered fan; the main and auxiliary power must be taken from a different bus segment but the main fan can be automatically transferred to Vice fan, but the deputy fan automatically go to the main extension prohibited. To ensure that the main fan power outage, the deputy for the wind turbine, and power outages can not face in production, there is a problem: When the main power outage dual power switch brands, the main fan and face equipment of all power, the main fan automatically switches to Deputy fans, by the fans for Face deputy for the wind, you can ensure the continuity of supply air Heading Face. But the monitoring equipment also power outages, stalled continuous monitoring surveillance. Although each monitoring system manufacturers in the design of the monitoring sub-station while providing standby power sub-station, according to the standard provisions should ensure that the system can provide power supply 2 hours of continuous monitoring equipment, but after a period of time, the standby power is lost due role. Solve this problem, from the local fan already has dual power to start, how to have dual power automatic conversion power monitoring and control equipment, taking into account the realization of local monitoring equipment maintenance outage, easy maintenance and replacement of the monitoring system. This is the development of monitoring equipment starting point dual power automatic switching device. Dual power automatic switching device is designed to meet the above requirements and carry out research and development. This device uses a coal mine power supply and fan dedicated power supply as the two inputs, including ventilation dedicated power supply as the main power supply, power supply as an auxiliary power source.
