Where is the leakage protection in the three-level distribution box
Implementation: Install one or more high-sensitivity leakage current protection relays on the incoming line side of each terminal distribution box (such as a lighting box or socket box). In addition to installing leakage protectors in the final switch box, a first level leakage protector should also be installed. "Two-level protection" mainly refers to the use of leakage protection measures, in addition to the final switch box to install leakage protection, but also in the upper level distribution box or general distribution box to install a leakage protection, generally forming two levels of protection. Each distribution box contains circuit breakers, fuses, and leakage current devices, which control and protect the electromechanical equipment and lighting circuits they serve.

Distribution box switch misalignment
Ensuring that the three-phase bases of a high voltage isolator switch sit on an identical horizontal plane prevents mechanical binding and contact failure. Misalignment disrupts synchronous phase operation, causing severe equipment damage and grid instability. They are often not used alone, but installed in distribution cabinets and distribution boxes, and used in conjunction with other electrical components in the circuit. It is widely believed that 50% of machine failures are due to misalignment. In case of a deviation of the belt from the intended track, a roller lever of these switches is the intended path, a roller lever of these switches is touched by the flank of the belt. Here are some of the most typical issues caused by poor alignment: Gaps or uneven contact surfaces can occur when the fixed and moving contacts are not properly aligned.

Distribution box switch alarm
The high and low voltage distribution cabinet monitors the current of each output shunt in real time, and can set the warning value of abnormal output shunt current. For example, if the alarm value of 32A switch is set to 28a, the load will alarm when it exceeds 28a. Intelligent power distribution box is composed of traditional leakage protector, air switch, AC contactor and KC868-H8. Compared with the traditional power distribution box, it is safer to cut off the strong power supply remotely, and it can save energy through the timing mode while controlling the. In many equipment, the distribution box will be used. When it is installed in some products, it can not only interrupt the power supply, but also assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in the enclosed or semi enclosed metal cabinet or panel.
