A conventional tank-type gas circuit breaker with a resistance is configured as described above. The resistance of the tank-type gas circuit breaker with resistance is mainly used for the purpose of reducing the re-surging surge that occurs when a high-speed reclosing of an unloaded transmission line is performed. In general, the smaller the value of the closing resistance, the larger the overvoltage at the time of inserting the closing resistance, and conversely, the larger the resistance value, the larger the overvoltage at the time of closing the main circuit.
Therefore, the resistance value has an optimum value. In the study of the optimum value in a general 500 kV system in Japan, it is said that a resistance value of 500 to 1200Ω has almost the same suppression effect, and it has a duty of high-speed reclosing of a 550 kV-rated no-load transmission line. A value of about 1000Ω is often used for a line gas circuit breaker.

However, the volume occupied by the resistor of 1000 Ω is very large, and in a normal circuit breaker, for example, the resistor 4 is arranged around the main breaking portion 2 as shown in FIG. It was arranged in the longitudinal direction of the main tank 1. Therefore, there is a problem that the tank diameter (φD) of the circuit breaker becomes large and the tank length (L) becomes long, so that the circuit breaker main tank 1 becomes large.

Further, in the substation, the tank type gas circuit breaker with resistance is required only for the circuit breaker and the circuit breaker for the busbar or the transformer circuit breaker does not need the resistor, so Two types of circuit breakers, a tank type gas circuit breaker with a built-in type and a tank type gas circuit breaker without resistance, are required, and there is waste in the manufacturing process of the circuit breaker, such as having two types of main circuit breaker main tanks 1 which are main components.

For the purpose of downsizing and eliminating the type of the circuit breaker main tank 1, the resistance contact 3 and the resistor 4 as shown in FIG. 11, for example, are housed in the second tank 11, and this tank is used. There has been proposed a circuit breaker having a structure that enables easy attachment / detachment. Then, a circuit breaker that does not require the resistance contact 3 and the resistor 4 is handled by a circuit breaker with the second tank removed, so that the first tank 9 is made into one type and the waste of the manufacturing process is eliminated, and the main circuit is shut off. At the same time, the tank that houses the part 2 has been made uniform.

However, this type of tank breaker with a resistance requires the third tank 22 and the fourth tank 25 in addition to the second tank 11, and the resistance contact 3 has the second tank 11. Since it is housed in, the rod 29 and levers 28, 30 for driving the resistance contact 3 are required,
The structure is very complicated. Further, since the resistance contact 3 has to be assigned to a position distant from the operation shaft of the operation device 5, the rods and levers are inevitably heavy, and the operation device 5 for driving this also requires a large operation force. As a result, there is a problem that the operating device 5 becomes large.

Further, since the insulating spacer 41 is inserted in the contact portion between the circuit breaker main tank 1 and the resistor tank 39, the main breaker 2 is mainly discharged from the fixed side when the short circuit current is cut off. Since the high-temperature hot gas does not directly act on the resistor 4 and the resistor 4 is protected and it is not necessary to design the insulation margin in consideration of the hot gas, the resistor tank 39 can be made small. It becomes possible to design. Further, by also using this insulating spacer 41 as a member for supporting the resistor 4, it also has an effect that the support structure of the resistor 4 can be simplified.

In addition, the insulating spacer 41 can also have a function of dividing the gas between the circuit breaker main tank 1 and the resistor tank 39, and when this function is provided,
For example, by increasing the gas pressure in the resistor tank 39 and further improving the gas insulation performance, the insulation distance between the resistor 4 and the resistor tank 39 can be reduced, and the resistor tank is further improved. It becomes possible to downsize 39.

Further, since the resistor tank 39 is arranged such that the axis of the resistor tank 39 is at a right angle to the axis of the circuit breaker main tank 1, the height limit is particularly limited when the resistor tank 39 is transported to the site. The vertical type GIS tank type gas circuit breaker has a merit that the total height of the circuit breaker can be kept low.
