Release time:
2021-08-18
High and low voltage distribution room power engineering equipment inspection can not be ignored, it is the key way to maintain the safety operation of electrical equipment. The maintenance of high and low voltage distribution room equipment is strict and wide. Only the terminal station has no starting point in the electric power safety production work! The inspection of power engineering equipment in high and low voltage distribution room can not be ignored, which is the key way to maintain the safe operation of electrical equipment.
High and low voltage distribution room power engineering equipment inspection can not be ignored, it is the key way to maintain the safety operation of electrical equipment. The maintenance of high and low voltage distribution room equipment is strict and wide. Only the terminal station has no starting point in the electric power safety production work! The inspection of power engineering equipment in high and low voltage distribution room can not be ignored, which is the key way to maintain the safe operation of electrical equipment.
The contents of safety inspection of high and low voltage distribution room are as follows:
1, check the power supply and distribution system route, no short circuit fault, load or operation error jump caused by partial or large-scale power supply system interruption.
2. All kinds of practical operation organization are flexible, touch is excellent, mechanical equipment interlock equipment is reasonable, and practical operation organization is oil moistening.
3, check the transmission line, very is the transmission line in and out of the branch pipe insulation is intact.
4. The operation sound of the transformer is stable, the temperature rise does not exceed the requirements, the natural ventilation equipment is excellent, the secondary working voltage of the power distribution system (in broad daylight) is 390V, and the ash removal screws of the transformer are tightened.
5. All kinds of circuit breakers, bus duct connectors touch well, no over-temperature condition, bus duct support frame is detailed, and bus duct is tightened.
6. The power capacitor has no bulging condition, excellent natural ventilation, and the temperature rise does not exceed 40 ℃; Check whether the three-phase current of each power capacitor is balanced.
7. The terminal block is clear and appropriate, and the tightening is reliable. The components of the automobile relay have excellent characteristics and the posture is flexible;
8, check the transmission line, very is the transmission line in and out of the branch pipe insulation is intact.
9, high and low voltage distribution indoor cleaning lighting is excellent, fire fighting equipment is abundant and detailed, to avoid animal invasion countermeasures are reasonable.
10. The fresh air system, exhaust system and central air-conditioning equipment of the high and low voltage distribution room are intact, and the temperature does not exceed 35 degrees.
11. Check that the cooling fan of the transformer operates well. The temperature control stores of the cooling fan of the transformer are adjusted to 80 ℃ to start and 60 ℃ to terminate.
12, fill in the relevant records.
Maintenance Contents and Common Problems of High and Low Voltage Distribution Room
The company has noticed that the electrical equipment of the processing plant is usually maintained, but whether it has fully considered the maintenance of the high and low voltage power distribution room of the power supply system terminal equipment of the electrical equipment? Many companies usually do not fully consider the equipment maintenance problems of the high and low voltage power distribution room, which leads to the generation of power engineering problems.
1. Pay attention to the cleaning of machinery and equipment at ordinary times
Because the vast majority of power engineering operation machinery and equipment are installed outdoors, according to this, in the daily maintenance and maintenance, the cleaning range of machinery and equipment must be increased. To clean up the operating machinery and equipment of power engineering, it is necessary to select effective and appropriate chemicals to clean up according to the technical standards of the actual machinery and equipment and their common problems.
2. Application of anti-corrosion measures to increase the use of machinery and equipment time

In the whole process of maintenance and maintenance of electrical equipment in high and low voltage power distribution room, corrosion prevention is very important, and it also has immediate harm to the use period of electrical equipment. In carrying out anti-corrosion work on electrical equipment, the main contents are as follows: for the exposed electrical conductor connector, anti-corrosion shall be given, and power engineering compound grease can be selected to wipe immediately to prevent air from oxidizing the connector and ensure that the connector is reliable in application.
3. Avoid moisture to ensure good operation of electrical equipment
In the high-voltage power distribution room, there are many problems such as high humidity and heavy moisture. In order to do a good job in the moisture-proof work of the high-voltage power distribution room, the following measures should be taken: first, the holes of the switch cabinet and the cable trench should be blocked and waterproof measures should be taken to ensure that the cable trench of the high-voltage power distribution room is isolated inside and outside and avoid the inflow of water in the cable trench of the high-voltage room. At the same time, plug the cable perforation of the distribution cabinet to avoid cable moisture affecting the high-voltage room switchgear.
4. Formulate emergency plan and enhance daily management
Through the daily maintenance and maintenance of power operation equipment, power enterprises have a general understanding of the actual operating conditions of the equipment. Based on this, they can predict the hidden or possible faults of the equipment, and formulate targeted emergency plans in advance to avoid the expansion of bad influence. At the same time, it is necessary to clearly point out the problem of the electric line, so as to provide convenience for troubleshooting the wire fault and continuously improve the work efficiency.
