Description of the invention (1) Background of the invention 1. Inventive part The present invention relates to a blow-type circuit breaker, which is designed to compress F6 gas in a blower and blow out compressed s to a contact part. F6 gas, and extinguishes the arc generated on the contact part. To be clear, the present invention is related to the grounding gate transmission device, which has an improved circuit breaker unit and is suitable for extending the interruptable arc time period. 2. General technology. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (谙 Please read the precautions on the back before filling out this page). The common circuit breaker is designed to interrupt one of the power transmission lines in the event of an accident, especially when lightning damage Feed the line and cut off the current flowing through it. However, if the circuit remains open, the power supply continues to be interrupted. To avoid this, the power transmission line is usually closed repeatedly in about one second. However, in the case of large power transmission systems, due to the high voltage of the transmission line The electrostatic capacity between the transmission line and the transmission line is large. Due to the static induction from & Good Patriarch, the duration of the _arc is prolonged, which makes it difficult to close quickly in about one second. However, This is not the case for the effective functioning of power transmission systems. In order to overcome the above problems, the two ends of the circuit planted by the fault of the high-speed automatic grounding device HSGS shown in Figure 8 are grounded to extinguish the secondary arc A2. Thereafter, the high-speed automatic grounding device is opened and the error of the interruption is interrupted. The phase is closed, however, during the opening operation of the circuit of the high-speed automatic grounding device, when an accident subsequently occurs, a zero loss situation may occur, in which the waveform of the AC current does not pass the zero level, as shown in the figure 2, and this error current in the case of zero loss of current cannot be applied to the standard of Chinese paper (CNS) A4 (210X297 mm) in the standard of this paper. 83. 3.10,000 -4-A7 ___ B7_,. V. Description of the invention ( 2) The circuit breaker is turned off. It usually takes about four cycles before the zero loss current condition returns to the current condition with a normal AC waveform. The time of about four cycles is equivalent to the arc extinction time of this subsequent accident, which is determined by the sum of the relay time of the two cycles and the interruption time of the two cycles from the detection of the subsequent accident to the generation of an interrupt command signal. Therefore, when it is necessary to cut off the current in the case of zero loss current by the gas circuit breaker, the gas circuit breaker needs to have a long cut-off time period of about one of four cycles. However, in the ordinary blower circuit breaker, all the compressed gas in the blower is blown out to the contact part at the end of the disconnection operation, which cannot achieve a long cut-off time period of about four cycles. To meet this need, the only common countermeasure proposed is to extend the distance between the two electrodes of the contact part, and J P — A — 6 3 — 88723 (1988) published an example of this common countermeasure. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs-As described in the general countermeasures, increasing the distance between the two electrodes of the contact part increases the volume and weight of the entire device, which also increases the volume and weight of the action unit of the circuit breaker . As a result, the space for the installation site of the device is also enlarged. SUMMARY OF THE INVENTION The object of the present invention is to provide a grounding switch transmission device, which can prolong the arc cutoff time period and cut off large currents without increasing the volume of the disconnection unit. In the grounding switch transmission device of the present invention, it is 83. 3. 10,000 (# first read the notes on the back and then fill out this page) This paper size applies the China National Elephant Standard (CNS) A4 specification (210X297 mm) ) Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V.

The circuit-on action is performed as follows. First, when an error occurs on the power transmission line and the circuit breaker at the two ends of the error phase acts to cut off the error phase, an external control unit sends a circuit-on command to the grounding switch transmission device, and a The action unit not shown pushes and drives the blower 1 1 upward in the figure. At this time, the late gas cylinder i moves further upward in the figure, and simultaneously pushes the SF 6 gas through a gas flow channel 3 into a first blowing chamber: 2 and a second blowing hole_1 0, and when a Move the contact 4 to. When the circuit-on position is reached and contacts the fixed contact 5, the circuit-on operation is completed, and then the induced current from the good phase begins to flow through it. At this time, the current flows through the wire 6 supported by an insulating cylinder 7 // the fixed contact 5, the movable contact 4, the blower 11 and the collector 8 to the other terminal 9, Then to the ground. The circuit cut-off action is performed as follows. First of all, when a circuit cut-off command is issued by an external control unit, the air blower applies the Chinese National Standard (CNS) A4 specification (210X297 mm) to the paper and paper scale from the action unit that is not shown. 83. 3_ 10,000 (please listen first (Read the notes on the mouth and fill out this page)

The invention description (5) is pulled down. At this time, the SF 6 gas filled in the first and second blowing chambers 10 and 10 starts to be compressed, and the two chambers 2 and 10 communicate with each other through a communication hole 16. When the disconnection operation is further performed, the movable contact 4 is disengaged from the fixed contact 5, and an electric arc is generated between the movable contact 4 and the fixed contact 5. At the same time, the SF 6 gas compressed in the first blowing chamber 2 and the second blowing chamber 10 blows out the arc generated between the movable contact 4 and the fixed contact 5 through the air flow channel 3, and extinguishes the Arc 0 ... When the disconnection operation is further performed, the blower 11 serving as a movable electrode reaches the disconnection position, and the disconnection operation is completed. However, the compressed SF 6 gas still accumulated in the second blowing chamber 10 and became a dead volume, and the SF 6 gas in the second blowing chamber 10 continued to flow out until the pressure in it fell to the ordinary pressure in the tank. until. At the end of the S F6 gas blowout, the current interruption is complete. Because the duration of this series of current interruption actions exceeds four cycles, and if a subsequent line error occurs and a zero loss current V occurs as shown in FIG. 2, the current interruption can be successfully performed, 'because of this The zero-loss condition returns to a normal current waveform after about four cycles. During the current interruption operation, the pressure changes in the first and second blowing chambers 2 and 10 are shown in Fig. 3 (B).

Invention Description (6 ) 10 achieved in the first blowing chamber 2. As can be seen from the above, the second blowing chamber is newly set in the portion of the flange that is usually used only to accommodate the blower, so as to increase the total volume of the blowing chamber, so that one consecutive arc in more than four cycles (of which there are Zero loss of current, which can occur at the moment of subsequent line faults) can be interrupted by a circuit breaker with approximately the same volume and slightly increased weight as ordinary. Hereinafter, other embodiments of the present invention will be described with reference to FIGS. 4, 5, 6, and 7. In these figures, all ground switch actuators are shown with their circuit switched on. In the embodiment of FIG. 4, the first blow_chamber_2 and the second puff_chamber X 0 communicate with each other through a through hole 12 provided in the shaft 1 of the blower 11 1. A particular advantage achieved by the embodiment of Fig. 4 is that the weight of the movable portion is reduced compared to the embodiment of Fig. 1. Although the fifth embodiment is similar to FIG. 4, the design of the through hole 12 in the shaft 1 of the blower 11 is not at the time when the circuit is connected. The first blower 2 and the second blower 10 In contrast, during the period during which the circuit is interrupted, the first blowing chamber 2 and the second blowing chamber 10 communicate with each other. A specific advantage achieved by the example in FIG. 5 can further extend the interruptable arc time f, except that the pressure increase of the S F6 gas in the second blowing chamber 10 is not as high as in the examples of FIGS. 1 and 4. In the embodiment of FIG. 6, a piston 13 may be provided in the second blowing chamber 10, and the SF6 gas in the second blowing chamber 10 is more effective than the embodiments of FIGS. 1, 4, and 5. Because the gas design in the second blowing chamber 10 is also blown out, the total amount of blown out gas is as shown in Figure 1.

Now, when the power transmission line A 1 causes a ground fault due to lightning, the circuit breakers CBA1 1 and CBA1 2 located at the two ends of the line A1 act and cut off the line A 1 and the busbar systems BA1 and BA 2 connection. After that, the high-speed earthing switch actuators HA1 and HA 2 are closed, and the line is connected to the ground potential, thereby extinguishing the secondary arc current that continues to exist at the fault point E 1, and then the high-speed earthing switch actuators HA 1 and HA are switched off. After 2 hours, the circuit breakers CBA1 1 and CBA1 2 provided at the two ends of the power transmission line A 1 can be closed to perform high-speed closing. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). Now, during closing of the high-speed earthing switch actuators HA 1 and HA 2 and after extinguishing the secondary arc current E 1 When another ground fault E 2 is generated by another phase, such as lightning, on the other phase, a so-called zero loss current condition (where the waveform of the AC current is suppressed and cannot cross the zero level, as shown in Figure 2 ) Appears in the current flowing through the high-speed grounding switch actuators HA 1 and HA 2, and the ordinary circuit breaker sometimes fails to cut off this current. It usually takes about four cycles to restore the zero-loss condition to the normal condition. The time of about four cycles is equivalent to the relay time from the detection of a subsequent error E 2 to about two cycles of generating an open circuit command signal and about two paper sizes. Applicable to China National Standard (CNS) A4 specifications (_ 210 X 297 mm) 83.3.10,000 -11-Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 _ · \ _ V. Description of the Invention (9) The sum of the open time of the circuit breakers CBB11 and CBB12 of the cycle. In order for the high-speed earthing switch actuators HA 1 and HA 2 to cut off the above-mentioned zero loss current, the high-speed earthing switch actuator needs to have a long cut-off time period of about four cycles. However, in the general blow type circuit breaker, all the compressed gas in the blow tube is blown out to the contact part at the end of the breaking operation, and it is impossible to achieve a long cut-off time period of about four cycles. In a gas circuit breaker having the blower of the present invention (wherein, * < SF 6 gas is compressed, and the compressed S F6 gas is blown out to the contact portion to extinguish the arc generated thereon), due to the setting The second air blowing chamber is located in the flange portion for accommodating the air cylinder, so the total capacity of the air blowing chamber is large, and the second air blowing chamber (set in the flange receiving part and maintained as a dead space) The S F6 gas can be blown to the contact part, even after the disconnection operation is completed, so that a zero loss of current can occur when a subsequent line error occurs. Jingzhi 1 is broken · The road device is cut off.
