Embodiment Construction

[0016] Displacement is a quantity related to the movement of the object's position during motion, and the range of displacement measurement methods is quite extensive. Small displacements are usually detected by strain gauge, inductive, differential transformer, eddy current, and Hall sensors, and large displacements are usually measured by sensing technologies such as inductive synchronizers, gratings, capacitive grids, and magnetic grids. Among them, the grating sensor has the advantages of easy digitalization, high precision (currently the highest resolution can reach the nanometer level), strong anti-interference ability, no artificial reading error, convenient installation, and reliable use. be increasingly widely used. Displacement sensors Displacement sensors are also called linear sensors, which are divided into inductive displacement sensors, capacitive displacement sensors, photoelectric displacement sensors, ultrasonic displacement sensors, and Hall displacement sen...

Abstract

The invention provides a method for monitoring the state of a plug-in type arrester, mainly solving the problem that the service life of the arrestor is short as a shielded plug-in type arrester can not monitor mounting accuracy, partial discharge property and insulating property are poor and ageing is easy in the prior art. The method for monitoring the state of the plug-in type arrester can realize real-time monitoring on the state of a cable terminal by virtue of a positioning device, when the terminal block of a cable or the cable moves downward owning to poor contact or drop, the movement can be visually observed by virtue of a signal indicating device, thus being convenient for repairing timely and avoiding accident and exacerbation of the accident; meanwhile operation is easy and simple, and applicability is strong.

Description

technical field [0001] The invention relates to a method for monitoring the plugging state of a plug-in lightning arrester, in particular to a method for monitoring the plug-in state of a plug-in lightning arrester. Background technique [0002] Currently, the global sensor market is showing a trend of rapid growth amidst ever-changing innovations. Relevant experts pointed out that the main technologies in the sensor field will be extended and improved on the existing basis, countries will compete to accelerate the development and industrialization of a new generation of sensors, and the competition will become increasingly fierce. The development of new technologies will redefine the future sensor market, such as the emergence of new sensors such as wireless sensors, fiber optic sensors, smart sensors and metal oxide sensors and the expansion of market share. Some sensor markets such as pressure sensors, temperature sensors, flow sensors, and level sensors have shown the c...
