In the figure, 27.4 is the power supply and load of the circuit in which the vacuum shield is installed, respectively, and 9.30 is the resistance and capacitance of the direction and the shielding capacity, respectively. /, J are the resistance and capacitance between the movable electrode d and the shield, jJa and JJb are the resistance of the insulating tube/l, respectively, 3rd is the capacitance between the shield and the ground, and Jj and JJ are the respective resistance and capacitance between the shield and the shield. These are the resistance and capacitance between electric poles and j in the interrupted thigh. When the degree of vacuum inside the vacuum breaker/7 deteriorates and the internal pressure rises, the #J11IL rate in the vacuum and the paddy electricity rate in the atmosphere are almost mixed, so the capacitance is 30.3,

性には例ら影響がない。6(B) shows the pressure received by the antenna 5 when the degree of vacuum of the vacuum interrupter 17 is normal. In this case, the voltage waveform between V and j is a sine wave, and no signal is input to the antenna jVl-. Voltage between poles and reception of antenna j when the degree of vacuum of vacuum breaker 17 deteriorates!
When discharge begins, the interelectrode voltage between the two electrodes does not rise above a certain voltage and ripples, as shown in FIG. 6(A). Figure 6 (B) at the start of this ripple
A pulse-like signal is generated as below, and by detecting and judging this signal, it is possible to detect the deterioration of the degree of vacuum in the vacuum chamber wI'rW/7. In this case, even if corona discharge occurs in a portion other than the threshold, the gI waveform is different, so the conventional characteristics are not affected.

きる。During ecstasy, a discharge occurs between the first lead and the intermediate shield with a floating potential, but unlike when the contact is opened, a weak signal is emitted into the air through the bushing and external connection conductor. . Therefore, the degree of vacuum in the vacuum pulp when the contact is closed can be determined by connecting the floating intermediate shield of the vacuum breaker and the tank wall (earth) with a capacitor, so that the measurable signal is the same as when the contact is open. Since it comes out, you can judge the success or failure of the vacuum level.

空度劣化を正確に検出することができるOConventionally, the quality of the vacuum of the vacuum pulp in a tank-type vacuum breaker has been determined by draining the insulating oil or insulating gas in the oil tank or gas tank, and then measuring the distance between the electrodes of the vacuum pulp for a pressure test. 111jil, applied a voltage, and investigated using the withstand voltage method. /c handicap was required and human error occurred when returning to 1, but according to the present invention, the vacuum breaker tIN4 can be opened without any manipulation of the oil tank or gas 4m, and when the vacuum level deteriorates, Paschen According to the law of the law, the electric discharge notes generated from the electric discharge bushing and the applied solution are received by the receiving antenna, and the good signals received by this antenna are electrically processed to detect the deterioration of the degree of vacuum. This advantage is that there is no need to remove the vacuum breaker from the circuit when detecting vacuum deterioration, and there is no need to install a separate high-voltage power supply due to the structure of the vacuum breaker. O that can easily and inexpensively accurately detect vacuum deterioration

(1) ()) In the 4th line of page 11 of the 911 Specification, the phrase ``the true 9 degree of the pulp'' is corrected to ``the true g! degree of the interrupter''. (1) - In the 10th line of page 7 of the specification, the phrase "applied. By the withstand voltage method" is corrected to "applied, by the withstand voltage method according to Paschen's law." (11 (!J) In the fourth line of page 7 of the specification, the phrase ``according to Paschen's law'' is amended to ``according to the precursor tax phenomenon affected by Paschen's law.''

度の良否を判定する真空置判定部とを備え、該真空度判
定部O出力により真空度劣化を検出するようにしたこと
′に41I黴とする真空し中断器の真空&監視装置。In a vacuum breaker that causes internal discharge when the degree of internal vacuum deteriorates, an antenna is provided near an external conductor of a grounding container in which the vacuum interrupter is housed, and receives a discharge signal caused by the internal discharge. , a vacuum position determination section electrically connected to the antenna and determining whether the degree of vacuum is good or bad based on the signal received by the antenna, and configured to detect deterioration of the degree of vacuum based on the output of the vacuum degree determination section O. What I did was to vacuum the 41I mold and use the interrupter vacuum and monitoring equipment.
