Abstract

PURPOSE:To enable the reduction of the installation area by a method wherein a cooler, blower, control panel, and the like are provided on the opposite side of the main circuit terminal of a thyristor valve with respect to a valve tank. CONSTITUTION:The main body 6 of the thyristor valve is housed in the valve tank 1, and the lower tank 8 and the valve tank are filled with an insulation medium 9 such as SF6 gas, which is then circulated and blown through the valve tank by means of the blower 10 in order to cool the thyristor in the main body, and is then cooled in the cooler 3. With respect to the main circuit terminal 7 connected to a gas insulation busbar 5, the cooler, blower, and control panel 4 are arranged on the opposite side of the valve tank. This manner enables the flow path of the cooling window from the cooler to be secured independently of the adjacent thyristor valve, and then this valve can be arranged in proximity.

Ｓにそれぞれ接続されてなるものである。In order to configure a power conversion device using such thyristor valves, a plurality of thyristor valves are combined and bridge-connected. FIG. 1 shows a conventional installation mode of such a power conversion device, which shows a pulp tank l housing the main body of a thyristor valve, a branch pipe surrounding the main circuit terminal led out from the pulp tank l, and a sealed valve tank. This is an example in which six closed-type silice valves, each consisting of a cooler 3 for cooling the insulating medium, a blower (not shown) for circulating the insulating medium, a control panel y, etc., are combined and connected in a bridge. The main circuit terminals of each thyristor pulp are connected to a gas insulated bus S, respectively.

Since the blower, control panel, etc. were arranged at right angles to the valve tank, it was necessary to secure a flow path for the blower in front of the cooler 3, so they were installed adjacent to the front of the cooler 3 at a certain distance. It was necessary to place thyristor pulp to Therefore, there was a drawback that the installation area of the entire silisk valve became excessively large.

きわめて好ましい有利な配置となる。Now, FIG. 9 shows the installation mode of a force converting device in which six sirisk valves having the above configuration are combined and connected in a bridge. With respect to the main circuit terminal 7 connected to the gas insulator IT, the cooler 3 and the blower IO1 control panel are arranged on the opposite side with respect to the valve tank 1).
Therefore, the cooling air flow path of the cooler 3 can be secured regardless of the adjacent thyristor pulp. Therefore, adjacent thyristor pulps can be placed close to each other, and the installation area can be significantly reduced compared to conventional ones. In addition, from the inspection passage and inspection work during maintenance,
This is a very favorable and advantageous arrangement.

However, it is not used for daily maintenance and inspection, but only in the unlikely event of an accident. Therefore, the inspection port /S is provided on the opposite side of the valve tank l from the control panel, that is, on the side of the main circuit terminal 7. In this way, the main circuit terminal 7 of the valve tank l
Since there are no parts on the side that require daily maintenance and inspection, adjacent thyristor valves can be placed close to each other as shown in FIG.
