表面に吹き付けられる。Next, the operation of the conventional resistor-type circuit breaker having the above structure will be described. For example, when a short circuit accident occurs in a power transmission line or the like, the line is cut off by a resistor-type buffer type circuit breaker in order to limit the range of the accident. This interruption operation is shown in the figure for the movable part which is composed of the movable main contact 1, the buffer cylinder 2, the insulating nozzle 3, the movable arc contact 4, the movable resistance contact 7, etc. in the buffer type circuit breaker with resistance. It is to move to the left (the direction of arrow B) in FIG. 4 (a) by a drive device that does not exist, whereby the breaking portion performs the opening / closing operation. In this opening and closing operation, first, the movable resistance contact 7 and the fixed resistance contact 10
Opens. This is because the moving speed of the movable resistance contact 7 is faster than the returning speed of the spring 10a provided on the fixed resistance contact 10 side. Next, the movable main contact 1 and the fixed main contact 8 are separated, and finally the movable arc contact 4 and the fixed arc contact 9 are separated. At this time, an arc 15 is generated between the movable arc contactor 4 and the fixed arc contactor 9. The insulating gas compressed in the buffer chamber 6 along with the separating operation of the movable portion is guided to the arc generation position by the insulating nozzle 3 and is intensively blown to the arc 15. The sprayed insulating gas is heated by the arc 15, and its temperature becomes a high temperature of several thousand to several tens of thousands. This high-temperature insulating gas passes around the fixed arc contactor 9, passes through the hole formed in the fixed side flange 14, and is sprayed on the surface of the resistor unit 11.

がある。Further, in the SF 6 gas circuit breaker, when the insulating gas SF 6 gas is blown to the arc 15, this gas is decomposed to generate SF 4 gas.
Gas is generated. This SF 4 gas is an extremely active gas and reacts with a trace amount of water in this gas to produce HF (hydrogen fluoride).
Occurs. This HF may attack the insulator formed on the surface of the resistor unit 11 and reduce the insulating performance.

必要がある。Since the conventional resistor-type circuit breaker is constructed as described above, the insulator on the surface of the resistor unit 11 is attacked by the high-temperature insulating gas heated by the arc 15. In addition, the fixed arc contactor 4 and the movable arc contactor 9 at the time of interruption.
There is also a problem in that the metal evaporated from the device adheres to the resistor unit 11 and the dielectric strength of the insulator on the surface of the resistor unit 11 decreases. In order to solve such a problem, it is necessary to prevent the hot insulating gas from coming into contact with the resistor unit 11.

The purpose is to obtain a buffer circuit breaker with a switch.

ものとなる。Next, the operation of the first embodiment of the resistor-equipped buffer type circuit breaker having the above-described structure will be described. For example, the breaking operation of the buffer type circuit breaker with a resistance due to a short circuit accident is caused by the movable main contact 1, the buffer cylinder 2,
Insulation nozzle 3, movable arc contact 4, movable resistance contact 7
By moving the movable part constituted by, for example, the left direction (the direction of arrow B) in FIG. 1A by a driving device (not shown), the breaking part performs the opening operation. With this opening operation, the movable resistance contact 7 and the fixed resistance contact 10 are first opened. This is the fixed side resistance contact 10
This is because the moving speed of the movable-side resistance contact 7 is faster than the returning speed of the spring 10a provided on the side. Next, the movable main contact 1 and the fixed main contact 8 are separated, and finally the movable arc contact 4 and the fixed arc contact 9 are separated. At this time, the arc 15 is placed between the movable arc contact 4 and the fixed arc contact 9.
Occurs. The insulating gas compressed in the buffer chamber 6 due to the opening operation of the movable portion is guided by the insulating nozzle 3 to the location where the arc 15 is generated, and is blown to the arc 15 in a concentrated manner. Then, the insulating gas having a high temperature passes around the fixed arc contactor 9, passes through the hole provided in the fixed side flange 14, and is guided into the gas guide cylinder 21 fixed to the fixed side flange 14. Then, by being mixed with the insulating gas in the gas guide cylinder 21, its temperature is lowered,
The gas is discharged from the end of the gas guide cylinder 21 and further mixed with a low temperature insulating gas. Therefore, the high-temperature insulating gas will not be directly blown to the resistor unit 11. Further, in the case of SF 6 gas circuit breaker, decomposed gas (for example, SF 4 gas) generated at the time of interruption is discharged from the end of the gas guide cylinder 21 and is connected to the resistor unit after a long time (minutes to hours) convection. Reach 11 However, this SF 6 gas circuit breaker is equipped with an adsorbent for the purpose of adsorbing SF 4 gas, HF (hydrogen fluoride) and water. For this reason, most of the decomposition gas generated at the time of interruption is adsorbed by the adsorbent during convection, and the influence on the resistor unit 11 is extremely small.

In the figure, the gas guide tube 22 is made of a conductive material (for example, aluminum), one end of the gas guide tube 22 is fixed to the fixed side flange 14, and the gas guide tube 22 is connected to a connecting portion 22a provided at the other end. A contact member 31 for connecting to the conductor is provided. Further, a hole 22b for discharging the insulating gas in the gas guide cylinder 22 is provided near the end of the gas guide cylinder 22 where the contact member 31 is attached. Further, the hole 22b is provided so that the discharged insulating gas does not directly contact the resistor unit 11. Since the gas guide tube 22 is made of a metal having the above-described structure, direct blowing of the high temperature insulating gas to the resistor unit 11 is prevented, and the gas guide tube 22 is also used as a current-carrying conductor. It becomes a buffer type circuit breaker with a resistor that can reduce the number of parts and downsize the device.
