Intelligent on-line monitoring device for transmission line bolts

model：DX-WPS100-LS

1、 Demand analysis

The state of the transmission line tower directly affects the safe operation of the transmission line. The bolt is an indispensable part of the tower structure, which is related to the stability of the entire tower structure. However, in the long-term outdoor environment, the bolt and other components, and the connection between components, are inevitably damaged or deformed, which may even cause serious accidents such as collapse. The transmission line intelligent bolt online monitoring device is a device that can accurately detect the axial force of bolts in real time and give early warning in time.

2、 Working principle

The bolt pretightening force sensor is specially designed to monitor the axial force of the bolt. A strain gauge is pasted on the bolt surface, and the bolt itself is made into a sensor, which can also be used as a common washer. The sensor can be used alone, or multiple sensors can be connected to the network, so as to continuously monitor the remaining bolt load from a connection point. It can monitor and transmit the stress change data in real time, and transmit the real-time data to the management personnel, so as to help the power workers to timely discover and take measures to solve the problem, and prevent economic losses and casualties caused by the tilt and collapse of the tower. The device is simple and practical, with a wide range of applications. It can be used in a variety of fields, and can provide powerful help to improve the monitoring system, improve the level of intelligence and automation, and ensure the safe operation of the unit.
