The first step is to test the display part of the primary circuit of the device. The testing method is very simple, which is to connect the device to the common terminal and the device with a short wire when it is powered on normally. When observing the display light in the device, it indicates that the display part of the primary circuit of the device is tested normally. Then conduct a power on test on the device, which means checking the indicator lights while the device is only connected to the power supply. Confirm that all indicators that meet the regulations are on, and if some indicators that are not included in the regulations are on, it indicates that the test is not qualified and needs to be repaired before retesting. Next, a test will be conducted on the internal temperature and humidity control part of the equipment. At room temperature, that is, normal ambient temperature, the temperature and humidity sensors and heaters associated with the equipment will be connected to the equipment accordingly. After subsequent power on, the following regulations need to be met. During the heating process in automatic mode, the heater will not generate output, and the fault indicator light and heating indicator light will not be illuminated. However, when switching to manual heating mode, the heater will start to output and the heating indicator light will be turned on, but the fault indicator light will still not be turned on. The fault indicator light will only be turned on when the heating is stopped, that is, when the heater is disconnected. Of course, if the sensor is placed in some low-temperature environment and the temperature drops below 5 degrees Celsius, the heater will also start to output, and the indicator light of the heater will also be lit. Once the temperature of the sensor reaches 15 degrees Celsius, the heater will stop output and the heating indicator light will also go out. In addition, if a humidifier is used to humidify the sensor, once the humidity of the sensor exceeds 90%, the heater will also start outputting and turn on the heating indicator light. Similarly, once the humidity of the sensor drops below 80% without continuous humidification, the corresponding heater needs to stop outputting and the heating indicator light should also be turned off p> Finally, we will conduct a test on the high-voltage live indication part of the equipment. Firstly, we will connect the terminals of the high-voltage live indication part on the equipment through live sensors for testing. Once the input voltage reaches 65% or more of the rated voltage, it is usually 10 to 15V. Remember not to exceed 20V, as it may cause damage to the entire equipment, The corresponding red indicator light will appear on the high-voltage live indicator section p>
The intelligent control device is a new multi-functional, intelligent dynamic simulation display and switch cabinet control device developed and designed based on the current development of medium and high voltage switch cabinet technology. It is suitable for various complete sets of devices such as central cabinets, handcart cabinets, fixed cabinets, ring network cabinets, etc. It integrates functions such as the simulation diagram of the primary circuit of the switchgear, the position of the handcart (isolation switch), the position of the circuit breaker (opening/closing status, spring energy storage status), the position of the grounding switch, high voltage live display (self inspection), live locking, phase loss alarm, detection and fault display of environmental temperature and humidity inside the switchgear, opening/closing, remote/local, manual/self storage control, cabinet lighting, RS485 communication, etc. This device not only has a beautiful and elegant appearance, but also optimizes the overall layout of the switchgear, making it an ideal replacement for the new generation of switchgear. The product meets the requirements of DL/T538-2006 (Technical Conditions for High Voltage Live Display Devices) P>
