Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an arc horn for a tension-resistant hanging device provided in electric equipment such as a power transmission line, and more particularly to a plurality of continuous-current interruption type flashover indicators. The present invention relates to a multi-action arc horn equipped with.

[Prior Art] As shown in Fig. 3, a conventional arc horn is provided with one follow-current interruption type flashover indicator (5). Since the fault indication is displayed only once, until the line is replaced after the operation, the line does not have the orientation for the lightning stroke and the follow current cutoff function, which may cause a problem such as deterioration of the line reliability. It was

In this case, the flashing indicator needs to be replaced after each operation, so there is no choice but to wait until the next work power failure or to provide a power failure time for installation. There was room for improvement in terms of.

The conventional example (Fig. 3) is an arc horn for flashing display developed by the applicant of the present invention, which has been experimentally implemented within the business range (commercial power supply area). In the figure, common reference numerals are given to members common to the configuration of the present invention.

[Problems to be solved by the device]

As described above, the conventional arc horn has one flashing indicator attached thereto, and various problems have arisen from the unilaterality of its operation.

The present invention has been made in view of such circumstances, and by providing a plurality of flashover indicators, it is possible to sequentially perform a plurality of lightning stroke displays and follow current interruptions, solve the above problems, and reduce power consumption. It is an object of the present invention to provide a multi-action arc horn that contributes to the stable supply of

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is designed so that, in an arc horn for a tension-resisting suspension device installed in electric equipment such as a transmission line, a flashover display due to a lightning strike and a follow-current interruption are sequentially performed multiple times. An operating arc horn, which is the ground side (hereinafter referred to as the E side) of a tension-resistant hanging insulator device. 2 or more and one or more arc horns on the line side (hereinafter referred to as the L side), and a follow-current interruption type flashover indicator on each tip of the E side arc horn. It is characterized by being attached. (Hereinafter, this is referred to as W horn.) [Operation] When a flashover occurs between any one pair of arc horns at the first lightning stroke, the above W horn has a flashover display attached to the E side arc horn. The vessel performs the operations of discharge and flight, and performs follow-current interruption and flashover display. So here
The E side may be restated as the cap side and the L side as the pin side.

Since the arc horn interval after the flashover indicator is activated is longer than when it was installed, there is no flashover between these arc horns during the next lightning stroke, and there is a flashover between the remaining horns with indicator. Is generated and the flashover indicator is activated.

Therefore, the W horn operates sequentially for the number of lightning strokes corresponding to the number of the equipped ones. That is, it is the one that has acquired multiplicity (multiactivity) functionally.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in Fig. 1, first, E of the tension-resistant hanging insulator string (4) is used.
Side (E side in the figure), two or more metallic arc horns (1) are attached to the mounting bracket (6), and the L side (L in the figure)
Side), one or more metallic arc horns (2) are attached to the fittings (6).

Here, the tip of the L-side arc horn (2) is formed in a circular shape in order to prevent generation of corona.

Further, as shown by broken lines in FIGS. 1 and 2, auxiliary horns (3) for assisting arc transfer may be attached to the E side and the L side, respectively.

Based on this configuration, as shown in FIG. 2, two or more flashover indicators (5) are attached to the E-side arc horn (1), and the multi-action arc horn of the present invention (the above-mentioned W horn). ) Is configured.

As shown by the solid line in FIGS. 1 and 2, the L-side arc horn (2) is one and the E-side arc horn (1) is two.
When the number is equal to or more than the number, the E-side arc horns (1) are arranged so as to be on the circumference having a radius of the horn distance between the E-side and the L-side. (Hereinafter, this is referred to as a one-end W horn.) When the L-side arc horn (2 ') and the E-side arc horn (1) are both equal in number to each other (in each figure, the L-side arc horn ( 2 ') is indicated by a broken line.),
The pairs are arranged so that they face each other, and the pairs are arranged at equal intervals. (Hereinafter, this will be referred to as a double-ended W horn.) [Advantage of the Invention] The present invention has the above-described configuration. According to this, in either the single-ended W horn or the double-ended W horn, the first lightning strike The flashover indicator is activated by the flashover generated between a pair of arc horns, and the remaining flashover indicators are activated by the next lightning stroke, so multiple arc horns and flashover indicators on the E side are used. By doing so, the flashing display of the lightning stroke portion and the follow-up interruption by the flashing can be sequentially performed multiple times (multiplicity).

As a result, the number of power outages of electric equipment such as transmission lines required for flashing indicator installation can be reduced, and the efficiency and reliability of transmission lines equipped with the arc horn of the present invention can be improved, contributing to a stable power supply. can do.
