Training on Maintenance of Rural Lighting Electrical Ready Boards: Cost saving and Worry free Daily Maintenance Techniques

Rural lighting electrical ready boards are the core equipment that ensures daily electrical safety. Regular maintenance can not only extend their service life, but also avoid safety hazards caused by electrical failures. The following provides practical and low-cost maintenance techniques from four aspects: cleaning inspection, component maintenance, environmental management, and emergency response, to help users achieve the maintenance goal of "saving money and worry".

1、 Daily cleaning and appearance inspection: low-cost hazard prevention

Regular dust removal to prevent short circuits

Tool: Dry soft bristled brush.

Operation: Clean the surface of the electrical ready board and the heat dissipation holes with a soft bristled brush every month to avoid dust accumulation and poor heat dissipation; Focus on cleaning circuit breakers, wiring terminals, and other parts to prevent dust from causing creepage or short circuits.

Cost: The tool is reusable, with a single cost close to zero.

Appearance inspection to prevent damage

Key points: Check whether the box body is deformed or cracked, whether the door lock is intact, and whether the sealing strip is aged and cracked.

Solution: If the box is found to be damaged, it should be repaired with waterproof glue in a timely manner. If the sealing strip is aging, it needs to be replaced (you can purchase a universal sealing strip and cut it yourself) to avoid rainwater, insects and ants entering and causing malfunctions.

Case: The electrical ready board in a certain village experienced a short circuit in its internal components due to rainwater infiltration caused by aging sealing strips; After regular replacement of the rubber strip, such faults have not occurred again.

2、 Key component maintenance: precise maintenance to reduce costs

Tightening of wiring terminals: anti loosening and resistance reduction

Cycle: Check the wiring terminals every six months and gently tighten them with a screwdriver to confirm that there is no looseness.

Tip: Apply moderate force when tightening to avoid excessive force causing thread slippage; If terminal oxidation is found, the contact surface can be lightly sanded with sandpaper and a small amount of conductive paste (such as Vaseline) can be applied to enhance conductivity.

Effect: Loose terminals can increase contact resistance, causing heating and even fire; Regular tightening can reduce the risk of contact failure by over 30%.

Circuit breaker testing: ensuring sensitivity and avoiding overload

Method: Conduct simulated overload testing annually at 80% -100% of the rated current of the circuit breaker (such as using a professional tester or contacting an electrician for assistance).

Standard: The circuit breaker should trip within 0.1 seconds, and if it operates slowly or fails, it should be replaced immediately.

Cost: The tester can be rented or brought by an electrician. The cost of a single test is about 50-100 yuan, which is much lower than the equipment damage caused by circuit breaker failure.

Leakage protector self check: prevent electric shock and ensure safety

Operation: Press the "Test" button once a month to confirm that the leakage protector can trip quickly (usually ≤ 0.1 seconds).

Attention: If the button does not trip after pressing, immediately contact an electrician for maintenance and do not disassemble it by yourself.

Case: A village experienced an electric shock accident due to the failure of a leakage protector. After strengthening self inspection, similar incidents did not occur again.

3、 Environmental Management: Optimizing Operating Conditions

Moisture and insect prevention: block loopholes to prevent corrosion

Measures: Install moisture-proof pads (made of plastic cloth or waterproof tape) at the bottom of the electrical ready board, and install insect proof nets (such as metal mesh) at the ventilation openings to prevent insects and ants from building nests or humid air from entering.

Effect: By installing moisture-proof pads and insect proof nets in a certain village, the humidity inside the electrical ready board was reduced by 40%, and the corrosion rate of components was reduced by 70%.

Heat dissipation optimization: reducing temperature and extending lifespan

Method: Ensure that there are no debris piled up within 1 meter around the electrical ready board and no obstructions on the top; During high temperatures in summer, a small cooling fan can be installed outside the box or a sunshade can be used to block direct sunlight.

Data: After heat dissipation optimization, the internal temperature of the electrical ready board can be reduced by 5-10 ℃, and the lifespan of components can be extended by more than 30%.

4、 Emergency Response and Recording: Rapid Response to Loss Reduction

Emergency response: Power outage troubleshooting to ensure safety

Step: If smoke, odor or frequent tripping of the electrical ready board is found, immediately cut off the main power supply, use a dry powder fire extinguisher (non water-based) to extinguish the initial fire (if it occurs), and contact a professional electrician for maintenance.

Taboo: Do not touch the internal components of the electrical ready board without power off to avoid electric shock.

Maintain records: track issues to improve efficiency

Tool: Create a simple maintenance record sheet (including date, inspection items, problem description, and handling measures) and post it on the inside of the electrical ready board.

Effect: By recording, repeated fault points can be quickly located. For example, if a circuit breaker frequently trips, it may require targeted replacement or upgrade due to excessive load or component aging.

5、 Recommended low-cost maintenance tools

Basic set: screwdriver set, multimeter, insulated gloves.

Advanced tools: infrared thermometer, conductive paste.

Alternative solution: Use the mobile infrared temperature measurement app (free) to preliminarily detect hotspots, or contact an electrician to borrow professional tools.

summary

The maintenance of rural lighting electrical ready boards does not require high cost investment. Through regular cleaning, precise maintenance, environmental optimization, and emergency management, "small investment, big guarantee" can be achieved. It is recommended that users establish a maintenance mechanism of "monthly self inspection+annual professional maintenance" and cultivate the habit of "handling problems immediately upon discovery" to avoid small failures turning into large losses.
