What is a substation? A: It is a power supply hub that receives electrical energy from the power system, transforms (boosts or downgrades), and then distributes the power. What is the main role of transformers in the power system? Answer: The main function is to convert the voltage to facilitate ...

1. About the electrical part: 1. The input side and output side of the miniature circuit breaker are inverted. 2. The voltage of the coil of the electrical parts does not match the voltage of the drawing, especially the voltage of the small relay and indicator light is easy to error. 3. The positive and negative polarity of electrical appliances is reversed, and the internal polarity of DC electrical appliances is reversed.

1. Check whether the filter screen of the Rittal air conditioner is blocked, if it is blocked, clean the lower filter in time. 2. Check whether there is any remaining freon in Rittal air conditioner, and if not, inform the professional maintenance personnel of the air conditioner to add fluoride in time. 3. Check the function of Rittal air conditioner.

Since ancient times, truss planning has been the way to create a stable and earthquake-tolerant mechanical structure. This plan consists of individual members connected at two ends, which form a triangle. The members are almost exclusively subjected to compressive or tensile forces, which makes the entire structure very strong.

What are the main differences between electronic control equipment and power distribution equipment products? Answer: The function of electronic control equipment is mainly control, and the function of power distribution equipment is mainly transmission. How much is the external design of domestic electronic control equipment products? Answer: Control panel, control cabinet, control box and console ...

1. In principle, the power cord and network cable of the cabinet should be sorted out separately; 2. The placement of the equipment should be appropriate, avoid squeezing each other, avoid being too high or too low, and avoid being too close to each other; 3. If there are too many devices in the cabinet, the equipment should be numbered; 4. For each line ...

The operating voltage of the cable Generally speaking, there is a certain relationship between the operating voltage of the cable and the rated voltage. If some cable lines are not in use, they must be connected to the power grid to ensure that the cable lines are not exposed to moisture. When the neutral point is not grounded ...

1. Preliminary preparation First of all, notify the user to label the cable and organize the cabinet without affecting the normal operation of the user. Then, according to the topology of the network, the existing equipment, the number of users, the user group and other factors, the internal lines of the cabinet are delineated.

The probable cause is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high. Causes and elimination of high pressure and overheating: 1. Too much refrigerant. Reduce the refrigeration dose appropriately. 2， ...

If the indoor temperature is higher than the outdoor one, or the indoor temperature is higher than the set temperature, the air conditioner will not start; Solution: Test the temperature comparison between indoor and outdoor to check whether the indoor temperature is too high. The voltage of the air conditioner is unstable, and the compressor cannot be started normally.
