Winter high-voltage switchgear failure caught people off guard, a few tips can help you

The weather in winter is very cold. Many people work in the company and find a daily food shop or cafe at night. They hardly go out. The indoor temperature is high and warm, and they feel very comfortable. Because it is winter, the electricity consumption is large and the load is high, which will cause electricity failure. It is necessary to do a good job in solving the failure in time to prevent adding trouble to oneself or others. Not only in daily life, but also in industrial and commercial power consumption, there will be high-voltage switchgear equipment failure, which makes people unprepared. Don't worry, a few small tricks can help you: We often have electricity failures in summer and never have failures in winter. This statement is wrong, so

What is high-voltage switchgear equipment and what is its role

What is high voltage switchgear equipment? High-voltage switchgear refers to electrical products used for power generation, transmission, distribution, power conversion and consumption in the power system to play the role of on-off, control or protection, with a voltage level of 3.6 kV to 550 kV, mainly including high-voltage circuit breakers, High-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic reclosing and segmenter, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry, and occupies a very important position in the entire power industry. Main part of ten kilovolt switchgear

The difference between high voltage switch cabinet and ring network cabinet

Switch cabinet is divided into high voltage switch cabinet equipment and low voltage. High voltage has ring network cabinet, middle cabinet, G G 1 A, etc. There are also many kinds of ring network cabinets. The so-called "ring network cabinet" of the ring network cabinet means that each distribution branch is equipped with a switch cabinet (outgoing switch cabinet), and the bus of this switch cabinet is also a part of the ring trunk line. That is to say, the ring trunk line is composed of the busbars of each outgoing cabinet connected together. Each outgoing cabinet is called "ring network cabinet". In fact, it is impossible to see the meaning of "ring network" by taking out a ring network cabinet alone. These ring network cabinets are not large, so the high-voltage switches of ring network cabinets generally do not use circuit breakers with complex structures.

What are the effects of condensation on high-voltage switchgear

1. Rust of the mechanism The transmission mechanism of the switch cabinet in the long-term wet operation environment often encounters deformation, bending, connecting rod breaking, crank arm breaking, transmission pin breaking, etc., resulting in difficult operation and heavy operation. Some connecting rods have small rigidity, serious corrosion, and severe mechanical vibration during operation. It is easy to cause the switch cabinet to be divided and rejected. The operating mechanism is stuck, the fuse connecting rod is broken and the interphase short circuit trips, or the single-phase grounding seriously affects the reliable operation of the switch cabinet. 2. Creepage After using for a certain period of time, the surface of the insulating part is often attached with dirt, which reduces the insulation strength of the insulating part, and causes the insulating material to be charged in the humid air.

Distribution cabinet in the rainy season, what problems should be paid attention?

I believe that the recent small partners have "changed the color of the rain". The terrible heavy rainfall has greatly damaged Henan. For the power distribution cabinet, it is also faced with realistic and serious problems. The water content in the air is large, and it is easy to form water droplets in the power distribution cabinet. A large number of water droplets gather in the power distribution cabinet for a long time, which will cause moisture and corrosion of the components in the power distribution cabinet, seriously threatening the operation of the power grid.

High-voltage switchgear quality and use time, which is important

The architectural style of shopping malls is different from the brands of merchants. Ordinary shopping malls are oriented to office workers and students. High-grade shopping malls not only have high product quality and peculiar styles, but also ordinary people are reluctant to buy. For business and white-collar people, they will buy 20 or 30 pieces at a time without hesitation and smile happily. Compared with the power industry, there are many types of products, many people buy them, and many budgets. They will choose cheap products, with short service life and many faults. Of course, there are also high-voltage switchgear with high-quality products. Compared with others, they save money, use them for a long time and use them efficiently.

What is the difference between substation and substation?

Change the voltage of the place. In order to transmit the electric energy from the power plant to a far place, the voltage must be increased to high voltage, and then the voltage should be reduced as needed near the user. This kind of voltage lifting work is completed by the substation. The main equipment of the substation is switches and transformers. According to the size of different, small called substation. The substation is larger than the substation. Substation: generally a step-down substation with a voltage level below 110KV; substation: including "step-up and step-down" substations with various voltage levels. Substation is a power system in the transformation of voltage, accept and distribute electrical energy, control the flow and adjustment of power.

Classification of Substation

(1) Outdoor substation. In addition to the control and DC power supply equipment in the outdoor substation, the primary equipment such as transformers, circuit breakers and blocking barriers are all installed outdoors. This kind of substation construction area is small, the construction cost is low, and the substation with higher voltage is generally selected for outdoor settlement. (2) Indoor substation. The primary equipment of the indoor substation is placed indoors, reducing the total land occupation, but the construction cost is higher, suitable for urban residents full area, or located in the coast, salt lake, chemical plant and other areas with high air pollution level. 3) Underground substation. In the personnel and industrial high concentration of large

The Difference Between Integrated Substation Automation System and Digital Substation

Regular substation is generally a common electromagnetic, capacitive transformer, secondary circuit cable substation; Integrated Substation is an additional integrated automation system on the regular substation, including data transmission, etc., in fact, the difference is not all; Digital substation uses photoelectric transformer, and the secondary circuit uses optical cable.
