Barrier Terminal Blocks Cause High Temperature Problems

Loose terminal blocks cause excessive loop resistance and over-temperature; terminal blocks are not loosened, but the control circuit is hot due to some unknown reasons, such as the power supply voltage is too high, or the load is short-circuited.

1. The working voltage is too high. It can be verified from the root cause that the working voltage of the secondary coil of the transformer-the working voltage in the power distribution cabinet-the working voltage of the power-consuming machinery and equipment. The power socket can also have an installation buckle and a locking buckle. The installation buckle can be more firmly fixed to the PCB board, and the locking buckle can lock the pregnant mother and the power socket after installation. Various power socket design schemes can be matched with different insertion methods of pregnant mothers, such as horizontal, vertical or skewed printed circuit boards. You can choose both metric and imperial linear rails as well as standard linear rails.

2. Common ground faults. It can also be verified from the transformer, and then grounded to the distribution cabinet. The grounding should be grounded, and all normal live and neutral wires should be cleared of common ground faults. When you can turn off the power, you need an insulation layer meter or a grounded shaker to measure accurately, and measure accurately in sections. As far as possible, measure cables, cables, disconnectors, power switches and other power supply and distribution system routes accurately. It is really impossible to section Under the situation, pull out the fuse of the weak current installation machinery and equipment, sensor technology machinery and equipment.
