Embodiment 1
Fig. 1 represents the end view based on the gas-insulated switchgear device internal structure of the embodiment of the invention 1, and the end view of switch element in Fig. 2 presentation graphs 1, Fig. 3 are the front views of Fig. 2, the front view of container in Fig. 4 presentation graphs 1, the end view of container in Fig. 5 presentation graphs 1.
In the drawings, the 21st, have the container of anterior container 22 and rear portion container 23.As shown in Figure 4, the cover plate 22a that closes the opening 20 (Fig. 1) that is used to insert and install a plurality of switch elements and draw part installation portion 22b forwardly is set in the container 22.Forwardly among the ring flange 22c of rear portion container 23 separated places of container 22 seal groove 22d is set, can be tightly connected with the ring flange 23a of rear portion container 23.
The 24th, run through the part of drawing of anterior container 22, at one end stube cable connector 25.26 is main circuit conductors that an end is connected with the other end of drawing part 24, and its other end is connected with the end of main circuit conductor 26a shown in Figure 3.On the other end of this main circuit conductor 26a, set circuit breaker 2 with rotary type movable contact.The 27th, the operating mechanism of operating by breaker operator axle 28 and 29 pairs of circuit breakers 2 of insulation link rod.
The 30th, as the vacuum type switch of the switch that is connected in series with circuit breaker 2, respectively in the movable and fixing docking point of dress and the movable contact side is connected on the insulating rod 31 by movable terminal 30a.The 32nd, the operating mechanism that is connected with insulating rod 31 by operating axis 33, the 34th, dress is received and the framework of structural members such as supporting vacuum type switch 30 and circuit breaker 2, and the 35th, the mounting base of installation frame 34 and operating mechanism 27,32 etc.
In addition, the composing method of the gas-insulated switchgear device of this embodiment 1 is with Fig. 2 and switch element 36 shown in Figure 3, as shown in Figure 1, in pack into anterior container 22 and the rear portion container 23, and to connect main circuit bus 5 and main circuit conductor 26 a plurality ofly.Switch element 36 has the function of a cover threephase switch unit certainly, and by the action of operating mechanism 27,32, operating axis 28,33 rotates, by insulation link rod 29, circuit breaker 2 carries out switch motion, utilizes again to make insulating rod 31 rise, descend, and vacuum shape switch 30 carries out switch motion.That is to say that switch element 36 has circuit breaker 2, breaker operator axle 28, insulation crosshead 29, three vacuum type switches 30, three insulating rods 31, operating axis 33 and frameworks 34.
In the gas-insulated switchgear device of aforementioned structure, assemble in the outside of container 21 respectively because of three switch elements 36, so guarantee the operating space, carry out assembling operation easily.In addition, can before installing to container 21, implement functional tests such as switching characteristic test, and can easily carry out essential adjustment.Again because of container 22 is forwardly inserted and is installed switch element 36, lead-through 24 and cable connector 25 by the front, promptly unidirectional installation, so can work for the simplification of assembling.
In addition, anterior container 22 and 23 conducts of rear portion container are divided into two parts near the middle part of front and back, and the container of a plurality of switch elements 36 of once packing into entirely, can reduce air seal place.Because of only forwardly container 22 switch elements 36 are installed and are drawn part 24 classes such as critical part such as grade, so can before rear portion container 23 is installed, carry out the connection operation of main circuit bus 5 grades, easy to operate.Because of the former configuration operating mechanism 27,32 of container 22 forwardly with draw part 24 etc., so can implement installation, cable construction and Maintenance and Repair etc. by the front certainly, operability is good again.
In previous embodiment 1, though adopt at opening 20 and draw part the shape that has step difference between the 22b is installed as anterior container 22, the shape of container is not limited thereto.As shown in Figure 6, for example also can make the structure that almost flat anterior container 41 is installed on rear portion container 42.
In addition, in aforementioned each embodiment,, also can be other switching device such as gas switch for example though be illustrated in example as switching device with vacuum type switch 30.
Moreover, in aforementioned each embodiment,, use respectively individually also can reach identical effect though be illustrated with vacuum type switch 30 and circuit breaker 2 tandem compounds.
