Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring instruments, in particular to an intelligent monitoring device for a lightning arrester. BACKGROUND

[0002] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltages and limit the time of current flow and also limit the amplitude of current flow. Since the lightning arrester is subjected to a very high operating voltage for a long time during operation, especially the widely used metal oxide lightning arrester, the valve piece will gradually deteriorate under long-term high voltage and large current conditions, and the leakage current will increase, accelerating the deterioration of the valve piece and increasing the temperature of the valve piece, which may cause an explosion of the lightning arrester. Therefore, the existing lightning arrester is often used with a corresponding monitoring device during use.

[0003] The lightning arrester monitor is connected in series in the lightning arrester grounding circuit. The milliammeter in the monitor is used to monitor the leakage current (peak value) through the lightning arrester under operating voltage, so as to determine whether the lightning arrester is damp, whether the components are abnormal, etc. The contamination meter is used to monitor the size of the contamination current (i.e. the size of the contamination) outside the porcelain sleeve of the lightning arrester. The action counter records the number of overvoltage actions of the lightning arrester. However, in actual work, as the use time of the monitor increases, the sealing rubber ring between the monitor and its end cover is prone to aging and other conditions, which may result in insufficient compression force. Since the monitor is mostly arranged outdoors, when it is in a rainy area or season, the problem of insufficient compression force caused by aging of the rubber ring may cause the monitor to leak water and other conditions, which may cause the electronic components inside the monitor to be damp and aged, affecting the monitoring results of the lightning arrester. Therefore, we propose an intelligent monitoring device for a lightning arrester. SUMMARY

[0039] Specifically, case one: when the rainfall is frequent, the rainwater drops into the rainwater collecting frame 8, the water-absorbing sponge 81 absorbs the rainwater and increases the weight, and the weight of the rainwater collecting frame 8 also increases correspondingly, the rainwater collecting frame 8 is lowered and compresses the spring body one 85, in the process of lowering, the driving column 82 drives the trapezoidal block one 83 to act on the trapezoidal block two 84, the trapezoidal block two 84 is driven by the acting force to drive the driving plate frame 95 to move directionally in the frame body 94, in the process of movement, the extension frame 97 on the side wall of the driving plate frame 95 moves synchronously (directionally moves in the strip-shaped groove 98), and the sliding column 901 on the extension plate frame 99 adjusts the position in the limiting groove body 90 under the action of the adjusting groove 903, so that the matching block one 904 shrinks to the frame body 94, in the process of movement, the matching block two 105 is acted on, the matching block two 105 is driven by the acting force to continue to compress the spring body two 102 of the protection shell 4, when the sliding column 901 moves to the end of the inclined area 905, at this time, the matching block one 904 is not on the movement track of the matching block two 105, neither hinders the matching block two 105, in this process, the electromagnet 103 is always in a power-off state (the matching block two 105 on the protection shell 4 is hindered by the matching block one 904, so that the protection shell 4 cannot move), the spring body two 102 acts on the protection shell 4, so that the protection shell 4 moves directionally under the action of the limiting column 101, the two protection shells 4 contact and form a complete protection shell 4 (the two protection shells 4 are provided with buffer rubber pads on opposite sides); when the rain stops, the protection shell 4 still protects the monitoring instrument body 3, prevents the weather condition from being thunderstorm or shower, and the weather is in a sunny state, the rainwater in the rainwater collecting frame 8 and the water-absorbing sponge 81 is gradually evaporated, under the action of the spring body one 85, the rainwater collecting frame 8 and the water-absorbing sponge 81 return to the initial state, the driving plate frame 95 returns to the initial state under the action of the buffer spring 86, and the extension frame 97, the extension plate frame 99 and the matching block one 904 in the extension plate frame 99 all return to the initial state, at this time, the electromagnet 103 is powered on, the protection shell 4 moves to the connecting plate frame 10 and compresses the spring body two 102, at this time, the matching block two 105 acts on the matching block one 904, the matching block one 904 no longer hinders the movement of the matching block two 105;

[0040] Case two: when the wind is strong, the fan body 7 drives the damping shaft 92 to rotate, so that the damping shaft 92 drives the cam body 93 to act on the roller set 96.
