EKQ2 series intelligent dual power supply automatic switching system for AC 50/60Hz, rated voltage below 1000V, rated current 2000A below the double power supply system, can achieve a common power supply (N) and (R) backup power automatic switching between (also can be set to manual switch), the double power supply users achieve unattended substation the. This product is suitable for extra class, class I power system, high-rise buildings, residential quarters, military facilities, hospitals, airports, docks, shopping malls, communication, fire protection, metallurgy, chemical industry, textile, oil, coal and other important places do not allow a blackout. This product conforms to the national standard IEC-947-6-1, GB/T 14048.11.
EKQ2 intelligent dual power automatic transfer switch (hereinafter referred to as the intelligent switch) is composed of two parts the device body and intelligent automatic controller;
Circuit breaker switch body consists of two units with electric operating mechanism (model specifications see technical parameter of terms) and accessories (auxiliary alarm contact etc.), mechanical interlocking, electrical chain, fuse, terminal etc., all components are arranged on a metal plate;
Intelligent automatic controller composed of novel single chip and module output etc.;
Between the two through the aviation plug interface dedicated and dedicated length of not more than 2 meters of the shielded cable is connected, an intelligent control system, intelligent control system of the power supply voltage is 220V, 50/60Hz;
The intelligent switch with mechanical. Electrical double chain protection function, provides a safe and reliable guarantee for your power supply;
The intelligent switch can complete the three-phase three wire, three-phase four wire double power supply automatic switching.
Intelligent switch principle of work: the simultaneous detection of two voltage controller. , and logic, the same delay (adjustable) circuit drives the corresponding instructions issued by the opening or closing instructions to the electric operating mechanism, the detection results can be displayed in the LCD display of intelligent automatic control panel, also can be connected with the computer through the serial port and using software control, for the user to find the reasons, so that the user in the shortest time to repair the fault line, the double power supply restoration of state. A, the ambient air temperature is -25 DEG ~+40 DEG C for 24 hours, and the average value of not more than +35 DEG c;
B, atmospheric conditions: the clean air, the relative humidity in the highest temperature of +40 DEG C of not more than 50%, allowing a higher relative humidity in the low temperature, such as +20 DEG C for 90%, but should be taken into account due to temperature changes, possible product condensation phenomenon;
C, the installation site altitude does not exceed 2000 meters, the indoor use;
D, the product should be installed in the absence of severe vibration and impact, not enough to make the electrical components should not be any corrosive;
E, if the condition is not satisfied, shall be borne by the user and the factory negotiated settlement;
F, when the product is used for offshore oil and nuclear power station, shall sign the technical agreement.
