Description

Technical Field

[0001] The present invention belongs to the technical field of grounding detection, and more specifically, relates to a grounding device suitable for a navigation light circuit and a navigation light circuit. Background Art

[0002] Dimmers play an important role in navigation lighting equipment. An airport with a turnover of tens of millions of yuan may use as few as one or two hundred dimmers, or as many as 500-600. Each dimmer device carries a navigation lighting circuit, and each circuit controls 30-200 lamps.

[0003] The navigation light circuit is a series suspended circuit composed of a constant current dimmer, a single-phase step-up transformer, an isolation transformer, and lamps. Its characteristics are that the light intensity of the lamps is uniform, the light intensity can be controlled within a certain range, the cross-sectional area of ​​the wire is small, and single-point grounding does not affect the operation of the lights.

[0004] When the insulation of the navigation light circuit is reduced, a ground fault will occur. When a single point of the navigation light series circuit is grounded, it will not affect the operation of the entire circuit and the lights in the circuit. When two points of the navigation light series circuit are grounded, the lights between the two grounding points will go out, affecting the take-off and landing or taxiing of the aircraft. In order to prevent a single point of grounding fault from occurring, which may cause the output circuit equipment to be unavailable. When the output circuit insulation is tested twice a month, a grounding point will be manually set for the output circuit insulation below 1 megohm to find out whether there is a grounding point in the output circuit in advance. Due to the large number of circuits and the small maintenance force, the maintenance time allowed for the operating runways and taxiways is relatively short. If conventional methods are used to eliminate it, it will seriously affect the operation and maintenance of other equipment. The method of using a single point of grounding to eliminate another point of grounding fault is 80%-90% shorter than the segmented insulation test method. However, each time the grounding is set, the screws need to be removed and the screws need to be tightened, and a long power outage is required. The preparation of intermediate safety protection supplies and tools requires two people to operate, which is time-consuming and labor-intensive. And the dimmer equipment usually uses artificial setting of grounding point to determine another grounding point, such as Figure 3 As shown, the simplest and quickest way is to make a grounding point on the output terminal A or B. Generally, the crimping method is adopted. The terminal and the wire are exposed, and the grounding wire is easy to be crimped improperly, which poses a certain safety risk.

[0005] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
