Description

Technical Field

[0001] The present invention relates to the technical field of lightning diversion, and in particular to a lightning limiter. Background Art

[0002] The design principle of the lightning limiter is to release the thundercloud charge in the form of a slow, small-current upward leader discharge or upward lightning flash, so as to avoid the hazards of strong downward lightning flash discharge. After the lightning is discharged through the discharge gap, a large part of the lightning energy is consumed and released, the lightning wave head is greatly flattened, and the lightning current amplitude is greatly reduced. On the basis of discharge, in order to ensure that the back-strike voltage generated by the lightning current flowing into the grounding system does not cause the line to trip, the current limiter further limits the lightning current after discharge, thereby greatly reducing the back-strike voltage of the grounding system and ensuring the normal operation of the transmission line under thunderstorm conditions.

[0003] When the existing lightning limiter is in use, the current flowing into the tower ground grid is large, which can easily cause abnormal line tripping. In addition, the limiter is installed at a high position, and it is easy to shake when encountering strong winds, which can easily reduce the stability of the limiter. After long-term shaking, the limiter is likely to loosen and detach, affecting its service life. Summary of the Invention

[0009] Beneficial effects

[0010] 1. By setting up the lightning rod and the discharge component, the device can prevent the lightning from being struck by lightning when in use. Because it is higher than the tower top and the overhead ground wire, it is connected to the lightning first. For the counter-strike lightning, the lightning rod is connected to the lightning first. The discharge gap between the discharge components consumes the lightning energy. The current limiter greatly weakens the lightning current flowing in the ground network, thereby avoiding the phenomenon of lightning counter-strike tripping.

[0011] At the same time, the device uses aluminum materials to increase the overcurrent area of the lightning limiter. The lightning rod is changed from a long needle to a slightly shorter aluminum rod, which avoids frequent lightning contact. In response to the situation where the resistance of the tower ground network is too high, the lightning current limiting measure of the lightning limiter is added to reduce the current flowing into the tower ground network and significantly reduce the back-strike voltage, thereby avoiding abnormal line tripping.

[0012] At the same time, when the probability of shielding failure of the protected object is allowed to reach 0.1% (the allowable value stipulated in the current regulations), the protection angle of the lightning limiter reaches 66.4°, thereby increasing the protection range;

[0013] At the same time, the upward discharge can be successfully induced by continuous discharge pulses, thereby improving reliability;

[0014] Small discharge current: the median value of the main discharge current is 5kA, and the steepness is less than 1.5kA / μs;

[0015] Easy installation and maintenance: easy installation and maintenance-free during the service life;

[0016] 2. By setting up the moving block and the outer rod, when the device is in use, the spring on the outside of the outer rod can continuously push the moving block and the curved plate to move, thereby automatically fitting with the outside of the main body. At the same time, after the device is installed, the clamping block can be fixed in contact with the inside of the clamping slot, thereby allowing the moving part to rise, and then the moving block is driven to move together through the guide part, so that the moving block can adjust the height of the support body, improve the support position, and thus improve the stability of the main body, avoiding large shaking after encountering strong winds;

[0017] 3. By setting a pushing block, when the device is in use and encounters strong winds, the guide plate and the diverter plate can be subjected to force, so that the connecting parts can be rotated. At the same time, the pushing block can be rotated outside the main body to control the main body. When the device encounters strong winds, the rotation force can be used to unload the force, thereby preventing the main body from loosening and detaching. BRIEF DESCRIPTION OF THE DRAWINGS
