1. The impact of lightning The armor components of the control cable are all metal conductors, and if the power line is short-circuited or lightning hits the metal parts, a strong current will be generated to destroy the optical cable line equipment, and even casualties will occur in serious cases. 2. Optical cable ...

What is the material of the busbar? A: Copper busbar, aluminum busbar and steel busbar. What is the significance of busbar coloring? Answer: It can increase the radiation capacity, which is conducive to heat dissipation, and the allowable load current can be increased by 12-15% after coloring. ...

1. Buried laying The laying method of laying the cable immediately underground is called buried laying. The buried cable must be armored cable and anti-corrosion coating protection cable, and the bare cable cannot be buried. Generally, the depth of the cable trench shall not exceed 0.9m, and the buried laying shall be paved ...

(1) The cause of moisture in the cabinet 1) Environment shutdown. The ring main unit or the opening and closing station itself is a closed environment, because of the poor ventilation conditions, it is easy to gather moisture and generate condensation, and there are many large buildings today in order to reduce the occupied area, the opening and closing station, the power distribution room is built in the basement. Cause...

1. When the electrical cabinet is used, the shell should be reliably grounded, and the electrical parts should be comprehensively inspected to eliminate the phenomenon of leakage and open circuit that may be caused by long-distance transportation, and check whether the voltage is consistent with the working voltage. 2. The electric cabinet is a non-explosion-proof oven, so it is flammable, explosive, volatile and corrosive.

Reliable supply wherever you are Tesvolt's large-scale industrial battery storage systems are based on standard products made by Rittal and guarantee a continuous power supply on the top of a mountain, by the sea or in the desert. The mountain peaks rise high above the crystal clear ...

51 What are the factors that affect the degree of harm to the human body caused by electric shock? Answer: Factors such as the magnitude of the current, the duration of the current, the path of the current, the resistance of the human body and the frequency of the current. 52 Types of electric shock? Answer: Direct electric shock, indirect electric contact, inductive ...

1. One spare core of the control cable is grounded It has been proved in practice that when a spare core in the control cable is grounded, the amplitude of the interference voltage can be reduced to 25%-50%, and the implementation is simple, and the cost of the cable is increased very little. 2. Serious consequences will occur when electrical interference is generated.

1. Filter maintenance of the indoor unit: The filter screen of the indoor unit generally needs to be replaced once every two months. It is not recommended to continue to use it after rinsing, because the rinsed filter is easy to stick, so that ventilation and ventilation are not smooth, and air circulation is affected. So if it's a one-off, direct replacement, not ...

1. The first is to measure how long the line is. According to the decision is to put the location of the distribution frame, and then combine the distance of the cable from the outside into the cabinet and so on to calculate how long the network cable needs to be put on the distribution frame and install the cabinet, so as to facilitate the overall cable management behind.

What is a control device? Answer: It is mainly used to control the switching appliances of the powered equipment and the combination of control, detection, protection and regulation equipment associated with these switching appliances. What is Overcurrent? A: Any electricity that exceeds the rated current. ...

The "Eastern Data and Western Computing" project aims to promote the rational layout of data centers, optimize supply and demand, green intensification and interconnection, so that the computing resources in the west can more fully support the computing of data in the east and better empower the country's digital development. 　　IT infrastructure is an important ...

Indoor unit: suitable for all kinds of control boxes, distribution boxes and electrical cabinets in machinery, electric power, chemical industry, textile machinery, automation equipment, instrumentation and other industries with high requirements for temperature and humidity. It can also be used to regulate temperature and humidity in small spaces. Outdoor unit: suitable for outdoor general base station, outdoor ...

1. The circuit breaker cannot be closed Causes: 1. The undervoltage coil does not work (the voltage is normal). Solution: Replace the undervoltage coil. 2. Press the closing button, and the closing coil will not work when it is powered up. Solution: Replace the undervoltage coil. 3. Cooperation...

1. The Rittal air conditioner does not start when it is turned on, and the A17 is faulty. Check that the power supply voltage is 220V, normal; Detect that the battery voltage of the remote control is 3V, which is normal; Measure the fuse resistance value of the air conditioner compressor with a multimeter as infinity, which is normal. 2. The Rittal air conditioner does not start when it is turned on, and the display is not started.

1. It occupies a small area. Generally, it is buried in the soil or laid indoors, ditches, tunnels, with a small insulation distance between lines, no towers, less land occupation, and basically no land on the surface. 2. High reliability. It is less affected by climatic conditions and surrounding environment, and the transmission performance is stable and the reliability is high. ...

1. The air conditioner shows the H1 fault code - the reason When the outdoor temperature is low and the humidity is high, the heat exchanger of the outdoor unit will be frosted after the air conditioner runs for a period of time, and then the automatic defrosting function will be activated, and the heating operation will be temporarily suspended for 5-10 minutes. Air conditioner heating defrost shows H1 which is normal ...

1) Fault phenomenon: The cause of this failure is the protection action. The high-voltage cabinet is equipped with protection against overcurrent, quick cut-off, gas and temperature. 2) Judgment method: The cause of the fault can be judged according to the relay card drop, remote signaling information, etc. After the action of gas and temperature protection in the high-voltage cabinet ...
