Maintenance of the busway

The busway needs maintenance when it is used. Everyone knows this, but how to carry out a maintenance and maintenance. Is there a lot of friends who know this? Busway is divided into many different types, just to adapt to different The working environment, the same everyone should do the maintenance work with a focus. First of all, for the maintenance of the busway protection circuit, this component plays an important role in the normal function of the busway. If you use the relevant temperature control during the process of using the busway, you cannot accurately and effectively reach the standard required for construction.

Intensive busway makes the power system no longer complicated

In many projects, the use of traditional power distribution systems often leads to complex engineering, especially for high-rise buildings and large factories. It is really not easy to get satisfied, but now it is dense. Type busway, the power system is no longer as complicated as before. In recent years, with the rapid development of China's economy, the demand for electricity for high-rise buildings and large factories has become more and more vigorous, because traditional power distribution equipment always makes engineering extremely complicated, so people appear in exploration. The busway, because of the busway, satisfies the building's need for electricity. in

China's nuclear power development ushers in the golden age

The launch of inland nuclear power is expected to show signs of warming in the near future. Entrusted by the National Development and Reform Commission, the Chinese Academy of Engineering and the China Nuclear Energy Industry Association recently conducted a survey on the site of the inland nuclear power plant to determine whether the safety of the inland nuclear power plant meets the requirements for construction, so as to clear the obstacles before the start of construction. At present, the investigation report on the construction of nuclear power in inland areas has been completed.

Long-term operation of the busway requires regular inspection

Before the maintenance of the busway, you need to check the busbar system for power failure! Completely block all power supply of the busway! Use a multimeter to measure the presence or absence of voltage of the conductor, and acknowledge that the busbar system is not powered before it can be routinely repaired. Avoid high voltages that cause physical damage to the operator. When the busway is operated for a long time, the temperature rise of the joint is detected once a year, and the temperature rise of the joint should be qualified according to the specification without exceeding 70K (the ambient temperature is 40 degrees). Check whether all the busbar joints and the conductors touch the surface. Avoid the occurrence of heat generation due to the increase in resistance caused by looseness. Check if the insulation material has an aging appearance.

Busway current differential protection

The low-impedance busbar current differential protection commonly used in China is not suitable for high-voltage busbars. When the busbar external fault is saturated, a large unbalanced current will appear in the busbar differential relay, which may cause the busbar protection to malfunction. High-impedance bus current differential protection solves this problem better

Advantages of high power filter modules in enclosed busway

The enclosed busway is used as a power transmission device, and is usually connected to the transformer while being connected to the power distribution cabinet. As a common power distribution cabinet-capacitor cabinet, it is a high-power filter module that converts electrical energy into storage and is commonly used in large electrical products. It has several advantages and plays an important role in power transmission control. Its main features are:
