Abstract

PURPOSE:To elongate the durable life of a lightning arrestor element by providing a dielectric resistant insulation cylinder with thin-walled portions at several locations to serve as discharge points of high temperature, high pressure gas produced in the dielectric resistant insulation cylinder. CONSTITUTION:Thin-walled portions 2A to serve as discharge points of high temperature, high pressure gas produced in a dielectric-resistant insulation cylinder 2 are formed on the dielectric-resistant insulation cylinder 2 so that the gas breaks through the thin-walled portions 2A and through a porcelain tube 5 to the outside. The behavior of the high temperature, high pressure gas at the time of discharge depends on the relationship between the gas pressure and the thickness of the thin-walled portion 2A. Namely, the gas breaks through the thin-walled portion 2A when it becomes impossible to stand the pressure any more and is discharged outside the porcelain tube 5. As a result, the shock of discharge is much smaller compared with the conventional discharge structure. This arrangement elongates the durable life of a lightning arrestor element 1.

(Problems to be Solved by the Invention) As mentioned above, conventional lightning arresters are installed on overhead power transmission line towers, etc., and when a power transmission line is struck by lightning, a lightning surge occurs on the transmission line, and If a lightning surge that is excessive and exceeds the design withstand M of the lightning arrester (1) is absorbed, flash faults will occur on the outer surface of the lightning arrester (1), causing the operating voltage or ground voltage of the power transmission and distribution line to decrease. A short circuit occurs in the lightning arrester element (1), and the internal pressure rises due to the high temperature and high pressure arc generated at this time, and as a result, the generated high temperature gas flows through the thin pressure relief port formed in the pressure-resistant insulation cylinder (2). Alternatively, the gas was discharged to the outside through a discharge gap formed between the cap metal fitting and the voltage-resistant insulating cylinder.

However, in this conventional lightning arrester, it is necessary to provide a special configuration to the voltage-resistant insulation tube (2) itself, and the voltage-resistant insulation tube (2) itself must be specially configured.
2) has to have a specific configuration due to the relationship with the cap metal fitting, which increases the number of man-hours in the manufacturing process and raises the processing cost. In the discharge structure of the vessel, the pressure relief port must be narrow due to the installation location.

For this reason, when the pressure is released, the high-pressure gas is released from the narrow pressure relief port or the discharge gap, so the pressure increases, and as a result, the voltage-resistant insulating cylinder (2) itself is destroyed and scattered, and the peripheral equipment is also damaged. Since damage may occur, the wall thickness of the voltage-resistant insulating cylinder must be thick enough to withstand this, which poses a major problem in terms of cost and weight.

Furthermore, the airtightness inside the voltage-resistant insulating cylinder deteriorates due to the fact that the pressure-resistant insulating cylinder (2) itself has a discharge port and a discharge gap is provided between the voltage-proof insulating cylinder (2) and the cap metal fitting. There is a concern that this may affect the service life of the lightning arrester element to be accommodated, and countermeasures against this are also required.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems, and includes one or more lightning arresting elements inside an insulator tube having openings on the ground side and the track side. In addition to accommodating a voltage-resistant insulating cylinder, the lightning arrester is provided with electrodes on the ground side and the line side, and the voltage-resistant insulating cylinder has a pressure release point for high-temperature and high-pressure gas generated within the voltage-resistant insulating cylinder. We adopted a configuration in which several thin-walled parts were formed.

(Function) According to the structure of the present invention, a thin-walled portion is formed in the pressure-resistant insulating tube as a pressure release point for high-temperature, high-pressure gas, and this thin-walled portion becomes a pressure-release point for high-temperature, high-pressure gas generated within the pressure-resistant insulating tube. This allows the high-temperature, high-pressure gas inside to break through the thin wall, penetrate the insulator tube, and be released to the outside.

Therefore, the behavior when high-temperature, high-pressure gas is released depends on the relationship between the gas pressure and the thickness of the thin-walled part of the pressure-resistant insulating tube. As mentioned above, the impact is small compared to conventional pressure relief structures because the pressure is released outside the insulator tube.

The optimal thickness of the thin part of the voltage-resistant insulating cylinder is 1/100 to 1/1O of the other parts of the voltage-resistant insulating cylinder, and the number varies depending on the length of the voltage-resistant insulating cylinder,
Approximately 4 to 6 pieces are appropriate.

The structure of the lightning arrester of the present invention is as described above, but it is installed on an overhead power transmission line tower, and as described above, when a lightning surge occurs on the power transmission line, this voltage is applied to the overhead power line. Although not shown in the diagram, the voltage is applied to the equipment, but when it is grounded to the ground via the steel tower, the gripping metal fitting → the electrode terminal on the line side of the lightning arrester → the lightning arrester → the electrode terminal on the grounding side → the mounting and hanging metal fittings → the lightning arrester when it is grounded to the ground via the steel tower. Discharges the large current of lightning surge and reduces lightning surge voltage on the line.

However, if an excessive lightning surge is received and a lightning surge that exceeds the design withstand capacity of the lightning arrester is absorbed, a flash short will occur on the outer surface of the lightning arrester, and the operating voltage or ground voltage of the power transmission/distribution line will be shorted at the lightning arrester. When the internal pressure rises due to the high-temperature, high-pressure arc that occurs during pressure release and exceeds the strength of the thickness Hl of the thin-walled portion (2A) of the voltage-resistant insulating cylinder (2), the thin-walled portion (2A) is broken and combined. The shrink tube (5) is also broken and the pressure is released to the outside.

(Effects of the Invention) The voltage-resistant insulating cylinder of the present invention has a structure in which several thin-walled parts are formed as pressure relief points for the high-temperature, high-pressure gas generated within the voltage-resistant insulating cylinder. , due to the relationship between the voltage-resistant insulating tube (2) and the cap metal fitting, which requires a specific configuration, or the fact that the pressure-resistant insulating tube (2) must be provided with a pressure relief port, the manufacturing process may be There was a problem that the number of man-hours increased and the processing cost soared, but the present invention eliminates these problems. Furthermore,
In order to suppress the increase in internal pressure, it is now possible to fill the gap between the element and the voltage-resistant insulating cylinder with an elastic insulating material, so the damage to the voltage-resistant insulating cylinder (2) itself when the pressure is released is minimized, and damage to peripheral equipment is also minimized.
