Circuit Breaker Lockout Equipment Control And Protection Functions

Circuit Breaker Lockout installation

Board connection: board wiring is the biggest feature is the replacement or maintenance of Circuit Breaker Lockouts, do not have to re-wiring, only the front power supply disconnected. Because of the special structure, the product has been designed according to the design requirements of the special installation board and mounting screws and wiring screws, need special attention is due to the reliability of large-capacity Circuit Breaker Lockout contact will directly affect the normal use of Circuit Breaker Lockouts, Must be taken seriously and strictly in accordance with the requirements of the manufacturer to install.

Plug-in wiring: In the installation of the complete set of equipment, the first installation of a Circuit Breaker Lockout mount, the installation of six plugs, the Circuit Breaker Lockout connection board has six sockets. The mounting seat has a connecting plate or a mounting seat, and the mounting seat is pre-connected with the power cord and the load line. When used, insert the Circuit Breaker Lockout directly into the mounting seat. If the Circuit Breaker Lockout is broken, just pull out the bad, put a good can. It is the replacement time than the board, board wiring is short, and convenient. Due to plug, pull need a certain amount of manpower. So China's plug-in products, the shell current limit of up to 400A. Thus saving maintenance and replacement time. Plug-in Circuit Breaker Lockouts should check whether the plug of the Circuit Breaker Lockout is tightened and the Circuit Breaker Lockout should be tightened safely to reduce the contact resistance and improve the reliability.

Drawer-type wiring: the Circuit Breaker Lockout into and out of the drawer is clockwise or counterclockwise rotation, in the main circuit and the secondary circuit are used

Plug-in structure, omitting the necessary isolation of the fixed device, so that a machine with two, to improve the use of the economy, while the operation and maintenance has brought great convenience, increased security and reliability. In particular, the main drawer seat of the drawer seat can be used with the NT type fuse breaker.

Circuit Breaker Lockout has a relatively important role in the whole power system, its role is to achieve the equipment control and protection functions, mainly in its control loop and protection, automatic devices and so on.

1. Circuit Breaker Lockout auxiliary contact conversion anomaly

When the Circuit Breaker Lockout is closed, if the green light flashes red or the traffic light is off, it indicates that the Circuit Breaker Lockout auxiliary contact is abnormal, Are also extinguished when the abnormal phenomenon.

2. Circuit Breaker Lockout auxiliary contact conversion exception handling

When the Circuit Breaker Lockout auxiliary contact conversion anomalies, the first thing to do is to report timely scheduling, view the background monitoring system signal, focusing on the situation of Circuit Breaker Lockout displacement, current, active is normal, if necessary, with the dispatch monitoring center , And then to the scene to check the Circuit Breaker Lockout secondary circuit and the mechanism, in the troubleshooting does belong to the Circuit Breaker Lockout auxiliary node problem, in order to avoid the switch of the normal division, must take the necessary measures. And timely report to the maintenance team, to be handled after power failure.

3. Circuit Breaker Lockout exception handling precautions

On the Circuit Breaker Lockout running, issued a control loop disconnection signal, causing this phenomenon for many reasons, must be based on the background machine-related information and on-site inspection equipment to analyze the situation, the power circuit is normal, the protection of the secondary circuit is Normal, switch the storage capacity is normal, switch SF6 gas pressure and other abnormalities. After the operation of the identified problems to take the necessary control measures, notify the relevant maintenance personnel to further investigation and handling, trying to equipment failure on the other equipment to minimize the impact of the grid.
