Disadvantages and improvements of closed busbars

Enclosed busbars are widely used electrical products in industries, residential buildings, and other sectors. They carry significant currents; therefore, even minor resistance changes in the power distribution system can generate substantial heat. Reducing the resistance of enclosed busbars is a key concern during installation. Typically, the resistance of the conductive copper bars in enclosed busbars is small; however, the contact resistance between the device and the plug-in box connector should not be overlooked. Often, enclosed busbars overheat and oxidize the surrounding copper bars when energized. Therefore, reducing the contact resistance at the busbar connections is crucial for ensuring the safety of the busbar power distribution.

Basic Introduction and Classification of Busbar Trunking

Busbars are enclosed metal devices made of copper and aluminum busbars, used to distribute high power to various components of a distributed system. They feature a series of matching components, commercial production, small size, large capacity, short design and construction cycle, easy installation and removal, non-combustibility, safety and reliability, and a long service life.

The importance of a closed busbar temperature monitoring system

The generating units of closed busbar power plants have been in operation for many years, resulting in equipment aging. The temperature controllers and temperature sensing elements of the power plant's temperature measurement system are frequently damaged. As a result, the temperature measurement points of various parts of the generating units cannot be monitored, increasing the workload of transportation personnel and posing a hidden danger to the safe and reliable operation of the units. It is recommended to carry out renovations as soon as possible to ensure the normal operation of the units. Let's take a look at the importance of the closed busbar temperature measurement system! The temperature measurement system of a closed busbar power plant mainly consists of a thermistor temperature sensor, a panel cabinet, signal cables, and a central control room. The thermistor temperature sensor measures the temperature of various parts of the generating unit through contact points, and transmits the data to...

Comparison of busbar trunking performance

Busbars have excellent heat dissipation performance. The insulating material of the cable (core insulation and sheath insulation) is both an insulating material and a heat-insulating material. Therefore, when laying power cables in cable trays, due to heat dissipation considerations, two layers can be laid at most. The busbar uses air conduction for heat dissipation, and the heat is dissipated through close contact with the steel shell, so its heat dissipation performance is comparable to that of cables. Busbars require almost no maintenance. Routine maintenance usually involves measuring the temperature rise of the shell core bolts and the cable inlet box joints, etc. If 4.8-grade core bolts are used, they need to be tightened regularly; if 8.8-grade high-strength bolts are used, then...
