Trouble phenomenon and maintenance of control circuit of power distribution box
In today's society, people's life is inseparable from electricity. With the improvement of people's living standards, the demand for points is also increasing. Therefore, the failure of the control line of the power distribution box will cause problems.
Our lives are directly affected. Below, the editor of our Shijiazhuang electrical distribution cabinet manufacturer will analyze the fault phenomenon and maintenance of the control circuit of the power distribution box for you The trick.

The failure of the power distribution box can generally be divided into two categories: natural failure and man-made failure, because it is mainly used in the motor control circuit. Natural failure is electrical insulation of power distribution boxDrop, contact welding and poor contact, poor contact of china outdoor patch cord wholesaler circuit contacts, deterioration of heat dissipation conditions, or even grounding or short circuit, it is often caused by overloading, vibration and vibration of electrical equipment during operation.

Caused by movement, metal chips and oil intrusion. If the human fault is light, the electrical equipment will not work, affecting the production, and the serious one will cause an accident. It is often due to the maintenance of the power distribution boxThe real cause of the electrical failure is not found, the components are replaced or the wiring is changed unreasonably, or the repair operation is improper, the basic concept is unclear, or the wiring is wrong when installing the control circuitThe electrical control circuit is faulty due to reasons such as errors. Therefore, the maintenance electrician should strengthen the daily maintenance and repair, eliminate the hidden dangers, prevent the failure from happening, and also make sure that the failure occurs.
Afterwards, it is necessary to find out the cause and eliminate the fault in time to avoid the loss caused by the accident.

We must understand the principle and master the correct maintenance method. Because there are many forms of electrical control circuits with varying degrees of complexity, their failures are often related to mechanical, hydraulicWhen the systems are intertwined, it is difficult to distinguish. There are many models and specifications of power distribution boxes, and the prices of different power distribution boxes are also different. Industrial power cabinets have higher powerThere is still a difference between large and lighting distribution boxes.

Faults are often only caused by problems with one or several electrical components, components or wiring. However, each electrical control circuit is often controlled by several electrical basic
Each basic control link is composed of fiber optic closure manufacturers several electrical components, and each electrical component is composed of several parts. Therefore, if we want to troubleshoot quickly and accurately, we need to Must be good at learning, general in summing up experience, find out the law, master the correct maintenance method.
