What Is Dielectric Gas?

Electrical equipment (Electrical Equipment) is a collective term for generators, transformers, power lines, circuit breakers and other equipment in the power system.

I. Qualifications and requirements of electrical operators:

(1) Electrical operations must undergo professional training, pass examinations, and hold electrician operation licenses.

(2) Electrical workers who have interrupted electrical work for more than six consecutive months due to some reason must pass a re-examination before they can work.

(3) Electrical personnel must strictly implement national safety operation regulations.

(4) Electrical workers must be strictly familiar with relevant fire fighting knowledge, be able to use fire fighting appliances and equipment correctly, and be familiar with emergency rescue methods for personal electric shock.

(E) change,

The so-called grounding refers to the electrical connection between a part of the electrical equipment and the soil. In order to ensure the normal operation and safety protection of electrical equipment, it must be grounded. For electrical equipment to be successfully grounded, grounding devices have to be used. The grounding device mainly includes two kinds of grounding wire and grounding body. The grounding body is a metal body used to directly contact the soil; the grounding wire is a wire used to connect the grounding body and electrical equipment.

Significance of electrical equipment

Doing a good job of troubleshooting the electrical equipment of the power plant can not only keep the power plant in safe operation all the time, but also improve user satisfaction with the work of the power plant. For the electrical equipment of the power plant, if there is a failure, it will not be able to provide users with electrical energy, and the user's production and life will be paralyzed. And if you do a good job of troubleshooting, you can discover the hidden dangers hidden in the electrical equipment in time, and eliminate the hidden dangers, so as to provide users with uninterrupted power supply to meet user needs, social production will not stop. Troubleshooting is of extraordinary significance ^[5] .

Electrical equipment equipment failure

After the electrical equipment runs for a period of time, it will inevitably be subject to wear or interference.

Insulation

Excluded from time to time will threaten the safe operation of electrical equipment. But to solve electrical faults, it is necessary to understand the common faults of electrical equipment:

(1) Short circuit.

The most important reason for the short circuit of electrical equipment is that the insulation layer no longer has the insulation ability, and the reason for this is that the insulation layer is wet or abraded, and some are caused by the insulation layer aging when the line is used for too long Coupled with the long-term disrepair of electrical equipment, short circuits can also occur.

(2) The temperature is too high.

For electrical equipment, wires must be required during operation, but each type of wire has its own maximum current load range. If the current load is abnormal and exceeds the original capacity of the wire, it will instantly increase the temperature of the wire and burn the wire. . The reason why this happens may be related to the lack of lubricating oil after long-term operation of the equipment. At the same time, it may also be that the equipment operating space is too small to release heat in a timely manner. In addition, the equipment was not cleaned of dust and debris in a timely manner

Arc and spark

It will also cause the temperature to be too high, thereby threatening the safety of electrical equipment.

(3) Arc and electric spark.

In the operation of electrical equipment, it is easy to produce arcs and electric sparks due to the damage of the wire insulation layer. Once this happens, it will directly threaten the overall safety of the power plant, especially the electric sparks are likely to cause electrical fires, which is extremely difficult to handle.

(4) Harmonics cause faults.

In the operation of electronic equipment, it is inevitable that harmonics will be generated. These harmonics have a great impact on electronic equipment, and will cause malfunction. It will easily threaten the safe operation of electrical equipment, and will also threaten the current operation, which is not good for the quality of the power grid Improvement ^[5] .

Solutions to electrical equipment

(1) Solutions to short-circuit insulation faults

In order to prevent the insulation layer from short-circuiting, it is necessary to do a good job of equipment and circuit layout to prevent damage to the equipment during use. At the same time, the anti-corrosion and moisture-proof design protects the insulation layer and prevents the insulation layer from directly contacting the outside world. In order to prevent the equipment from suddenly stopping work and inducing fire, you can use dual power supplies and ensure that the two power supplies can be switched at will. Once one power supply stops working, the other power supply can take over its work in time.

Dual power

This can also provide a certain amount of time for repair personnel to successfully complete the repair task. At the same time, to avoid short-circuiting due to grounding, you can add a metal shell for electrical equipment. This way can also effectively prevent unnecessary danger caused by high temperature.

(2) Solutions to wire heating

In order to reduce the adverse effects caused by the heating of the conductor, the conductor should be selected in accordance with the actual situation of the electrical equipment, and the maximum load of the conductor should be calculated to control the load of the conductor. In the application, once the electrical equipment fails, the device will automatically alarm, and related staff can also carry out repair work according to the prompts. Relevant staff of the enterprise should also regularly maintain electrical equipment, and according to the maintenance plan, clean up debris and dust on the equipment, give the electrical equipment sufficient operating space, and ensure that heat can be released in a timely manner. In addition, the relevant staff must also make temperature detection and records to check whether the electrical equipment is abnormally high in use. If this happens, it is necessary to immediately take measures to reduce the temperature to prevent unnecessary high temperatures. damage.

(3) Solutions to arc and electric spark

As electrical equipment is prone to arcs and electric sparks during operation, equipment that is prone to arcs and electric sparks should be kept away from dangerous sites, emergency measures should be taken, and appropriate protective equipment should be provided. Can be used for cables that are not easily ignited

filter

There are flammable wires, and daily inspection should be done at the same time. This can also prevent the occurrence of insulation damage. Once abnormalities are found, they must be dealt with immediately.

(4) Solutions to Harmonics

Because electrical equipment is susceptible to harmonics in use, and harmonics cannot be eliminated automatically, this requires changing the structure of the converter and applying certain control strategies to eliminate harmonics. At the same time, you can also use a scheme to suppress the generation of harmonics, such as applying filters to prevent electrical equipment from being interfered ^[5] .
