[Prior Art] In the power-receiving equipment, a vacuum circuit breaker for breaking the load current or the accident current is installed, and when the load is checked for maintenance, the system voltage and current are used to ensure the safety of the operator to open the switch and the grounding switch. The detection device also houses a lock-type switchboard (called a switch gear) such as a protective relay. The switch transmission is insulated in various ways. In addition to the conventional gas-insulated discs, which use SF6 gas cabinet type GIS, there is a solid insulation, compressed air insulation, and full vacuum. Insulation and other products have been put on the market, and various insulation methods have been used to accelerate the miniaturization of the circuit breaker, the open switch, and the grounding switch. It is proposed to integrate the open circuit, disconnect, and grounding functions into a vacuum tube in a single container. It is housed in an insulating gas container (intensive switching actuator) (for example, refer to Patent 1). Patent Document 1: Japanese Laid-Open Patent Publication No. Hei 9-153320. SUMMARY OF THE INVENTION The above-described intensive switching transmission device is a vacuum electron tube that is integrated in an open circuit, disconnected, and grounded in a single container, and is housed in an insulating gas container (5). 1313530 Hereinafter, an embodiment of a vacuum insulated switchgear according to the present invention will be described using a drawing. 1 is a side view showing an embodiment in which the vacuum insulated switchgear of the present invention is applied as a feeder tray; FIG. 2 is a front view showing a first diagram; and FIG. 3 is a perspective view showing a second diagram. . In the drawings, the casing 1 of the vacuum insulated switch transmission device is provided with a low pressure control section 2, a high voltage switch section φ scribe section 3, a busbar, and a cable section 4, which are respectively partitioned by a ground metal plate from above. In the bus bar and the cable section 4, a solid insulated bus bar 5 is disposed, and the cable head 6 on the line side, the insulating sleeve C T6 and the like are provided. Further, a vacuum two-point disconnection three-position type opener is disposed in the high-pressure switch section 3 (vacuum two-point disconnection three-position type open circuit disconnection switch BDS), and a grounding switch (ES) having a vacuum input container 9. Voltage detector (v D ) 10 and operating device 1 1. The busbar 5 is made of a fixed insulation and is gas-free to ensure its handling properties and safety. Further, the voltage detector 1 is a corona which detects the deterioration of the degree of vacuum in the vacuum container to improve maintenance and inspection.

The grounding switch BDS) is in the vacuum 82, and the structure is 83. It is not 85 by the P 8 6 〇 vacuum capacity insulation lever 111 to stop at the I Y1 > voltage. In the open position, open the gap -10- (7) Ι 3 Ί 3530 g3. The breaking gap g3 is set to have an inter-electrode distance which is approximately doubled the breaking gap g2. In this way, the breaking gap g3, |^ at the time of disconnection is set to approximately twice the breaking gap g2, and the plurality of windings (two in the transmission jj) are used as the insulation capable of performing the multi-stage form. In addition, the phase-to-phase is molded and insulated, and the vacuum-insulated contact between the poles, @the above-mentioned inter-electrode size and the number of poles is used to set "interphase insulation" and g-insulation when disconnected> inter-electrode insulation at the time of disconnection> The _ φ system of the interpole insulation of the grounding switch is used to achieve the insulation coordination between the phases. Thereby, at least the grounding of ~g is suppressed, and the occurrence of an accident can be suppressed as much as possible. Further, the air-insulated operating lever 8 8 is covered with a bellows or metal bellows 89 as shown in Fig. 1, and is blocked by the outside air. Thereby, the _ middle insulating operation lever 8 8 is ensured to be reliable for insulation for a long period of time. As shown in Fig. 1, the grounding switch (ES) 9 having a vacuum input container is provided with an insulating cylinder The vacuum container 91 is fixed in the vacuum container #9 1 and is connected to the fixed contact 92 of the feeder 89 and its movable contact 93. A vacuum insulated operating rod 94 is coupled to the movable contact 91. The vacuum insulated operating rod 94 is led out of the vacuum container 9 via the metal bellows 95, and is connected to the insulating operating rod 1 1 2 for the grounding switch. The above vacuum containers 80, 91 are provided. The operating lever is made of stainless steel to improve its environmental resistance. Further, each of the movable contacts 93 is connected by a conductor 96 as shown in Fig. 2 . Hereinafter, the closed position Y1 for switching to the energization of the shutter 8 and the open position Y2 for the breaking current, and the voltage of the -11 - 13 (13) 1313530 for the lightning or the like are used to secure the inspection worker. The third configuration of the disconnection position Y3 used for safety and the detailed configuration of the operation device 1 1 for operating the grounding switch 9 to be turned on and off. The components of the operating device 1 1 are fixed to a support plate 3 provided in the high-voltage switch section 3. The operating device 1 is substantially constituted by a first operating mechanism 200 for switching the movable contact 82 of the shutter 8 to the closed position Y1 and the open position Y 2 for moving the movable contact 8 of the shutter 8 2 The switching operation is constituted by the second operating mechanism 300' in the open position Y2 and the open position Y3 and the third operating mechanism 400 of the movable contact 9 of the grounding switch 9. First, the configuration of the first operating mechanism 200 will be described using Figs. 6 and 1; first, in Fig. 6, the first shaft 20 is rotatably supported by the support plate 113. As shown in Fig. 1, on the first shaft 201, the three rods 202 are fixed in the axial direction of the first shaft 201. The front end side of the rod 202 is coupled to the operating lever 1 1 1 , respectively. Further, as shown in Fig. 6 and Fig. 1 'on one side of the first axis 20 1 , the rod 2 〇 3 is fixed in the opposite direction to the rod 2 0 2 . As shown in Fig. 6, the drive shaft 206 of the electromagnet 205 is coupled to the rod 2 〇 3 via the connecting member 704. A movable iron core 207 having a T-shaped cross section is fixed to the drive shaft 206. A fixed core 208 fixed to the support plate 1 13 is disposed around the movable core 207. Inside the fixed core 208, a coil 209 and an annular permanent magnet 200 are disposed. On the opposite side of the rod 203 of the drive shaft 206, a trip spring seat 2 is provided. Between the trip spring seat 2 1 1 and the fixed iron core 2 0 8 , a trip spring -12-(9) 1313530 2 12° is arranged. The electromagnet 205 is held in the closed position at the movable contact 82. The state of γι 'by the attractive force of the coil 209 and the permanent magnet 2 成为 becomes a pressure-corresing spring (not shown) that is provided against the trip spring 2 1 2 and the gas-insulated operating lever 8 8 The power of retention. In particular, it constitutes the attraction force of the permanent magnet 2 1 , and is called the magnetic locking method. Hereinafter, the configuration of the second operating mechanism 300 for switching the movable contact 8 2 φ of the shutter 8 into the open position Y2 and the open position Y3 will be described using FIG. 6; the first on the support plate 1 1 3 A rod 3 0 1 is fixed to an intermediate portion of the shaft 2 0 1 in the longitudinal direction. An interlocking pin 302 is provided on the front end side of the rod 310. At the pin 302, a roller 303 is abutted. The roller 303 is rotatably provided at one end of the crank lever 306. The crank lever 306 is rotatably supported on the lower side of the support plate 113. A drive shaft 306 of an electromagnet 305 is coupled to the other end of the crank lever 306. A movable iron core 307 is fixed to the drive shaft 306. A fixed core 308 fixed to the support plate 1 1 3 is disposed around the movable core 3 07. Inside the fixed core 308, two coils 3 0 9 and 3 1 0 are arranged in the vertical direction. A return spring 31 1 is disposed between the movable core 3 07 and the upper portion of the fixed core 308. The electromagnets 3 0 5 operate the movable iron cores 3 0 7 in the upward and downward directions by exciting the coils 3 0 9 and 3 1 0. By this action, the crank lever 3 04 is rotated. By the rotation of the crank lever 306, the abutment position of the interlocking pin 308 and the roller 303 is changed, and the lever 203 can be prevented from rotating around the first shaft 2 〇 1 or can be rotated. Thereby, the movable contact -13-(10) 1313530 point 82 of the shutter 8 is blocked from the open position Y2 to the open position Y3 to the open position Υ2, or to be movable from the open position Υ2 to the open position. That is, this configuration is the first interlocking mechanism that becomes the movable contact 8 2 Υ 2 of the shutter 8 and the disconnected position Υ3. Hereinafter, in particular, the configuration of the third operating mechanism 400 for operating the ground-open movable contact 93 will be described with reference to Fig. 6, and the second shaft 401 is rotatably supported by the support. As shown in Fig. 1, 402 has three rods 402 fixed to the distal end side of the axial direction 4〇2 of the second shaft 401, and are respectively coupled to the operating lever 1 1 2 . Further, the rod 403 is fixed in the opposite direction to the rod 402. As shown in Fig. 6, the rod 403 has a drive shaft 406 having an electromagnet 405 via a coupling member. The electromagnet 405 has the same configuration as the electromagnet 205 having the first operating mechanism 200, and a movable iron core 407 having a cross-sectional shape in a meandering shape is fixed at 406. Around the core 407, a fixed iron fixed to the support plate 1 1 3 is disposed inside the fixed core 408, and a wire 圏 409 and a ring 410 are disposed. Between the fixed iron core 4〇8 and the lower surface of the support plate 1 13 , a road spring 41 1 is used. The third interlocking mechanism is provided between the third operating mechanism of the grounding switch 9 and the opening and closing movable contact 82 between the open position Υ2 and the open position γ3 and the second operating mechanism 300. The second interlocking mechanism is configured such that the movable contact in the shutter corresponds to a surge voltage of a lightning strike or the like to secure the position 3 of the inspection operator's open position Υ3, and can be maintained by the electromagnet 405. The opening position of the closing device 9 is: the plate 1 1 3, the second axial direction. The rod, such as the 6th 〇 4 0 4 link, has the movable iron core 40 8 with the drive shaft described above. The permanent magnet can be used with the breaker 8 and the eighth one can be used. The safety is broken. The grounding is opened. -14. (13) 1313530 The movable contact 93 of the closed device 9 is connected to the fixed contact. When the movable contact 8 2 is located at the two positions of the open position γ 2 for breaking the current, the electromagnet 405 makes it impossible to connect the movable contact 93 of the grounding switch 9 to the fixed contact, and also to the grounding switch. When the fixed contact of 9 is turned on by the movable contact 9 3, the operation of the electromagnet 205 of the second operating mechanism 300 is not performed. Specifically, the second interlocking mechanism is composed of a pin 412 disposed at a lower end of the driving shaft 406 of the electromagnet 405 of the third operating mechanism 400, and below the electromagnet 305 of the second operating mechanism 300, and the second shaft. a shaft 4 1 3 ′ disposed in parallel with the shaft 401 and a rod (not shown) provided at the lower end of the drive shaft 306 of the electromagnet 305 connected to the second operating mechanism 3〇〇, and the shaft 401 413 and configured by a rod 414 that engages with the pin 412. Hereinafter, the operation of the vacuum insulated switchgear according to the present invention as an embodiment of the feeder pan will be described using Figs. 1 to 6 . In a state where the movable contact 82 in the shutter 8 is set to the open position Y2 for breaking the current, the first operating mechanism 200 is caused by the restoring force of the trip spring 212 of the first operating mechanism 200. The lever 203 gives a rotational force in the clock direction with the first axis 2 0 1 as a fulcrum in Fig. 1 . Thereby, the interlocking pin 301 provided on the distal end side of the rod 301 which constitutes the second operating mechanism 300 is abutted against the outer circumference of the roller 303, and the return of the jumping spring 2 1 2 is suppressed. The force is more clockwise. That is, it is prevented from moving from the open position Y2 for breaking the current to the off position Y3 for ensuring the safety of the worker for the surge voltage of the lightning or the like. Hereinafter, an operation (on operation) from the open position Y2 of the first operating mechanism 200 to the closed position 1-1 (12) 1313530 position Y1 will be described. When the coil 2 0 9 of the electromagnet 2 0 5 of the first operating mechanism 200 is energized, the drive shaft 206 moves upward in the sixth drawing. By moving the drive shaft 206 upward, the lever 202 pivots in the counterclockwise direction with the first shaft 201 as a fulcrum, and moves the movable contact 8 2 toward the closed position Υ1. In this closed state, the trip spring 212 and the pressure receiving spring are in a state of being energized and having an opening operation. φ Further, by the input operation, the interlocking pin 312 is in a state of being separated from the outer circumference of the roller 309. Further, the roller 3 0 3 is held at the initial position by the return spring 3 1 1 of the second operating mechanism without causing a positional change. As described above, when the shutter 8 is in the closed state, the second operating mechanism 300 is disabled by the opening operation of the first operating mechanism 200, and the mechanical interlocking mechanism is constituted by the viewpoint of enhancing safety. It is also possible to realize the disconnection and disconnection of the mechanical interlocking mechanism in one of the cases where "the movable contact exists in the closed position, and the disconnection operation is impossible". - Hereinafter, an operation (opening action) from the closed position Υ1 of the first operating mechanism 200 to the open position Υ2 will be described. When the coil 209 of the electromagnet 205 of the first operating mechanism 200 is excited in the opposite direction to the closing operation, the magnetic flux of the permanent magnet 2 1 0 is eliminated, and the spring 2 1 2 and the crimping spring are The force is applied such that its drive shaft 206 moves downward in FIG. By the movement of the drive shaft 206 toward the lower side, via the rod 2 0 3, the first shaft 201, the rod 301 is rotated in the clockwise direction in FIG. 1, but the rotation of the rod 310 in the clock direction, It is suppressed by the -16 (13) 1313530 that the interlocking pin 302 of the second operating mechanism is in contact with the outer peripheral surface of the roller 303. As a result, the movable contact 82 of the shutter 8 can be held at the open position Y2. The following description explains the disconnection position Y3 (opening operation) from the open position Y2 of the second operating mechanism 300. In the open state of the above-described shutter 8, when the upper coil 3 0 9 of the electromagnet 3 0 5 of the second operating mechanism 300 is excited, the drive shaft 3 0 6 resists the return spring 3 1 1 and moves upward. . The drive shaft 306 is moved upwards, and the roller 3 0 3 is rotated in the counterclockwise direction in Fig. 1 via the crank lever 306. By the rotation of the roller 303 in the counterclockwise direction, the contact position of the roller 303 and the interlocking pin 310 is lowered downward. As a result, via the lever 301, the first shaft 201 and the lever 202, the operating lever 111 is moved upward, and the movable contact 82 of the shutter 8 is moved to the disconnected position Y3. In the disconnected state, the movable iron core 207 of the electromagnet 205 of the first operating mechanism 200 is present below the permanent magnet 210. Therefore, even if the coil 209 of the electromagnetic iron 205 of the first operating mechanism 200 is excited in the OFF state, the magnetic flux passing through the movable iron core 207 hardly attracts the attraction. In other words, it is possible to realize a mechanical interlock of the circuit breaker and the disconnect switch, and it is impossible to make the "on operation" when the movable contact exists in the open position. Hereinafter, the operation from the off position Y3 to the open position Y2 of the second operating mechanism 300 will be described. In the off state, when the lower coil 3 1 0 of the electromagnet 2 0 5 of the second operating mechanism 3 00 is excited, the crank -17-(14) 1313530 shank 3 is moved by the upper side of the drive shaft 2 0 6 . When the clock direction of 04 is rotated, the roller 303 is pushed upward by the interlocking pin 302 that abuts against it, so that the movable contact 82 of the shutter 8 is moved to the open position Y2. Thereafter, when the movable contact 82 of the shutter 8 is in the open position Y2 for breaking the current, the lever 4 14 of the second interlocking mechanism is engaged with the electromagnet 405 provided in the third operating mechanism 400. The pin 412 at the lower end of the drive shaft 406 is thus made to be movable to the movable contact 93 of the ground switch 9 by the electromagnet 405. 'When the fixed contact of the grounding switch 9 turns on its movable contact 9 3 'the rod 4 1 4 ' of the second interlocking mechanism is engaged under the driving shaft 4 〇 6 provided on the electromagnet 405 Because of the pin 412, it is impossible to operate by the second operating mechanism 300. Moreover, when the movable contact 82 of the shutter 8 is in a surge voltage for lightning or the like, it is used to ensure the safety of the inspection worker. At the position Y3, the rod 4 14 of the second interlock mechanism is made to move the pin 412 provided at the lower end of the drive shaft 406 of the electromagnet 405, so that the grounding switch 9 can be turned on by the third operating mechanism 400. Further, in the above embodiment, the roller 3 0 3 ' rotated freely from the second operating mechanism 300 is used as the partial arc-shaped cam. Further, the first operating mechanism 200 and the third operating mechanism 400 may be changed as appropriate. Further, the electromagnetic operation mode is applied to the first operating mechanism 2000, but other operation modes such as an electric spring method may be employed. According to the above-described embodiment of the present invention, the vacuum insulated switchgear can be reduced in size and weight, and the performance and reliability can be improved. Moreover, by using the compact and lightweight vacuum insulated switchgear, it is possible to provide a feeder tray in response to user requirements of -18-(15) 1313530. 7 and 8 are views showing an embodiment in which the vacuum insulated switch device of the present invention is applied as a bus bar, and Fig. 7 is a view showing the ground switch of the present invention as an implementation side of a bus bar.
