How to avoid electrical accidents from distribution boxes to home safety?

2023-09-22

Electrical accidents not only pose a threat to personal safety, but also cause damage to property, so ensuring electrical safety is very important. This article will introduce how to avoid electrical accidents from the distribution box to home safety.1、 Safety of distribution boxesJiangsu distribution box is the core of the entire circuit and one of the control centers of the circuit.Installation positionThe distribution box should be installed in a well ventilated, dry, moisture-resistant area, gradually avoiding direct sunlight and flammable materials, and avoiding areas where personnel frequently move. Be sure to be at least 1.8 meters above the ground to prevent children from accidentally touching.protective measuresThe distribution box should be equipped with a leakage protector, which is an effective protection against personal electric shock. Once there is leakage, the leakage protector will automatically trip.Inspection and maintenanceRegularly inspect and maintain the di...

Key points for preventing electric shock in switchgear

2023-09-22

There are 7 typical risks associated with switchgear wiring.1. In the voltage transformer cabinet, the lightning arrester is directly connected to the busbar;2. There is a live busbar connected from adjacent cabinets at the bottom of the busbar switchgear;3. The switchgear adopts a dual busbar connection method, which can introduce the operating busbar voltage into the maintenance room;4. The lower part of the switchgear is not completely isolated from the rear, and maintenance personnel can access the rear live equipment;5. The upper part of the switchgear is not tightly sealed, and the live busbar can be seen;6. The switchgear belongs to the main transformer incoming cabinet, with live contacts or the ability to make phone calls at any time;7. The switchgear belongs to the contact cabinet, and the contacts can be electrified or make phone calls at any time.Three isolation measures should be taken during maintenance.When charging the static contact of the switch, the static contact ho...

The difference between switchgear and distribution box

2023-09-22

A switchgear is an electrical device. The internal and external wires of the switchgear go first to the main automatic switch inside the cabinet, and then to the sub automatic switch. Each branch is set according to the requirements. For example, instrument dials, automatic control systems, motor magnetic induction switches, various DC contactors, etc. Some are also equipped with high voltage and low voltage room switchgear, high voltage busbars such as power stations, and some are also equipped with low cycle load shedding to maintain critical machinery and equipment.The primary function of the switchgear is to perform power switching, operation, and maintenance on electrical equipment during the power generation, transmission and distribution, distribution equipment, and power engineering transformation operations of the power supply system. The components inside the switchgear are mainly composed of isolation switches, high-voltage isolation switches, load power switches, actual ...

How to prevent fire accidents in distribution boxes?

2023-09-22

With the continuous development of society and the improvement of people's living standards, electricity has become an indispensable part of our lives. However, due to the inherent characteristics of electricity, electrical fires often occur. As an important equipment for power distribution and control, distribution boxes are also one of the high-risk areas for fires. Therefore, it is crucial to prevent fire accidents in the distribution box. This article will introduce how to prevent fire accidents in distribution boxes from the aspects of installation, use, and maintenance.Firstly, the installation of the distribution box is very important. Before installation, we need to ensure that qualified distribution box products are purchased. Qualified distribution boxes should comply with relevant national standards and have fire, explosion, and electrical withstand voltage capabilities. During the installation process, it is necessary to pay attention to correct grounding, ensure nor...

How to solve the leakage of power distribution box switches?

2023-09-22

How to solve the problem of power distribution box switch leakage.Firstly, we need to understand what leakage is. Leakage refers to the loss of current from the circuit of the power supply equipment to the ground or other conductors, rather than flowing normally to the electrical equipment. When the leakage current exceeds a certain level, a leakage protector will be triggered, causing the circuit to disconnect, in order to prevent further current loss and other hazards.Once we find a leakage in the distribution box switch, we first need to disconnect the power supply to ensure safety. Next, the following steps can be taken to solve the leakage problem:Check the electrical equipment: Some leakage problems are caused by damage to the electrical equipment itself. Therefore, each electrical device can be checked one by one to identify potential leakage points. If equipment damage or signs of loose wiring are found, the equipment should be replaced or repaired immediately.Check sockets and...
