Rural lighting electrical ready board: anti electric shock design and renovation

The anti electric shock design and renovation of rural lighting electrical ready boards can start from optimizing the installation position and structure of the electrical ready board, configuring internal safety devices, upgrading materials and processes, and improving supporting safety measures. The following is a specific analysis:

Installation position and structural optimization of electrical ready board

Reasonably plan the installation location: The electrical ready board should be installed in a dry, ventilated area that is not easily accessible to children, avoiding installation in damp, water prone, or areas with frequent human activities, such as near bathrooms, kitchen sinks, etc., to prevent electric shock accidents caused by damp environments or accidental contact.

Adopting a closed structure: The electrical ready board should be designed as a closed type, and the box door should be equipped with reliable locks. Only professionals can open it for operation and maintenance, preventing non professionals from touching the internal electrical components at will and reducing the risk of electric shock.

Internal safety device configuration

Installing a leakage protector: Install a suitable leakage protector in the electrical ready board, which can quickly cut off the power supply and protect personal safety when a leakage occurs in the circuit. The operating current and operating time of the leakage protector should be selected according to the actual situation of rural lighting electricity consumption. Generally, a leakage protector with an operating current of 30mA and an operating time not exceeding 0.1s can be selected for household lighting circuits.

Set up overload and short circuit protection devices: equipped with suitable circuit breakers or fuses, which can promptly cut off the circuit when overload or short circuit faults occur, avoiding electrical fires and electric shock accidents caused by excessive current. The rated current of the circuit breaker should be reasonably selected based on the load capacity of the lighting circuit.

Material and process upgrade

Select high-quality insulation materials: The electrical components and wires inside the electrical ready board should be made of materials with good insulation performance to ensure effective prevention of current leakage and ensure personnel safety during normal operation and fault situations.

Improve the level of processing technology: The outer shell of the electrical ready board should have good protective performance, smooth edges, no burrs, and prevent personnel from being scratched during operation. At the same time, the internal wiring should be neat and firm, and reliable crimping or welding processes should be used at the wire connections to prevent poor contact from generating electrical sparks.

Complete supporting safety measures

Set up warning signs: Post obvious warning signs on the outer shell of the electrical ready board, such as "High voltage danger, do not touch", etc., to remind personnel to pay attention to safety and avoid misoperation.

Strengthen the promotion of safe electricity use: Through bulletin boards, brochures, training and other methods, popularize safe electricity knowledge to rural residents, improve their safety awareness and self-protection ability, and teach them not to privately connect wires or touch electrical equipment with wet hands.
