Problems solved by technology
[0003] Among them, the nuclear magnetic resonance method is a new detection method, which has been widely promoted because of its accurate detection. However, although the existing nuclear magnetic resonance device is easy to carry, there are still many shortcomings in the detection speed, and it is difficult to quickly complete the circumference of the entire composite insulator shed. direction detection, and if it is used for online detection, there are many deficiencies in operation

Embodiment Construction
[0022] The present invention will be further described below with reference to the embodiments and the accompanying drawings.
[0023] refer to Figure 1 to Figure 5 The shown all-round and efficient online detection device for composite insulator shed mainly includes two bases 2 and two magnet modules 1. As shown in the figure, in this embodiment, the base 2 is generally a disc-shaped structure, and the base 2 The middle part of the base 2 has an engaging hole 20 running through its upper and lower sides, the thickness of the middle part of the base 2 is greater than the thickness of its outer edge, and it is formed by two semicircular parts 21, that is, the end surface of one of the semicircular parts 21 has a vertical outward extension. If there is a plug 12, the other semicircular part 21 has sockets 11 that cooperate with the plug 12, and they are distributed in a staggered manner, so that the base 2 can be quickly snapped and fixed to the mandrel of the insulator (only o...

The invention discloses an all-round high-efficiency online detection device for composite insulator sheds, which comprises two magnet modules and two bases, one of the magnet modules is provided with a radio frequency coil and a tuning and matching circuit connected thereto, and the tuning and matching The circuit is connected with a transmission cable, the base is in the shape of a disc, and the middle part has a concentric locking hole, and the base includes two semicircular parts, and the two semicircular parts have a mutual engaging structure; An annular chute is provided on the outer edge of the base, and the magnet module can slide and fit with the base through the annular chute, and can perform circular motion relative to the engaging hole. The magnet module is supported by the base, and can slide along the circumference of the base, so as to achieve the purpose of quickly measuring one circle of the shed, and the detection efficiency is high.
Description
technical field [0001] The invention relates to the field of power equipment detection tools, in particular to an omnidirectional and efficient online detection device for a composite insulator shed. Background technique [0002] Composite insulators are widely used in high-voltage transmission lines due to their light weight, high mechanical strength, not easy to break, and good pollution resistance. The composite insulator shed is the outer insulation of the composite insulator, which is used to protect the mandrel from the erosion of the atmosphere, provide the necessary creepage distance, and improve the pollution resistance. During the operation of the composite insulator shed, its quality plays a crucial role in the power transmission. Therefore, the detection of the composite insulator shed material is of great significance. At present, the online detection method of the composite insulator shed material mainly includes direct observation. method, ultraviolet imaging...
