Embodiment:
In conjunction with the accompanying drawings the structure of electric railway of the present invention with armored withdraw type metal enclosed switchgear is illustrated.
Shown in Fig. 1-6, the armored withdraw type metal enclosed switchgear of electric railway of the present invention, this equipment includes cabinet 1, insulating sleeve 8 is equipped with at top, cabinet 1 rear flank, supporting insulator 9 is equipped with in cabinet 1 line-in and line-out chamber 16, the indoor vacuum circuit-breaker 4 of one pole in the breaker chamber 13 is provided with secondary plug 2 and is plugged on the cabinet 1, fixed contact 5 is fixed in the insulation contact box 7 at cabinet 1 middle part and with main bus bar 11 and is connected, jam plate 3 on the one pole valve mechanism 6 is housed in the breaker chamber 13, at the rear portion of cabinet 1 one pole earthed switch 10 is housed, ground connection operation 22 is positioned at a forequarter of cabinet 1, and cabinet 1 bottom is equipped with current transformer 12 and is connected with main bus bar 11.
1 of described main bus bar 11 and cabinet are provided with insulating sleeve 8, supporting insulator 9, insulation contact box 7 and current transformer 12 isolates; 5 of described circuit breaker 4 and fixed contacts have one pole valve mechanism 6 to isolate.
When circuit breaker 4 is in test position, can operates one pole earthed switch 10 combined floodgates main bus bar 11 is carried out effective grounding.When circuit breaker 4 was in the service position during described one pole earthed switch 10 separating brakes, the secondary plug 2 in the circuit breaker blocked by jam plate 3, can not be pulled out.
As shown in Figure 2, armouring cabinet 1 has secondary meter chamber 14, breaker chamber 13, bus-bar room 15, the outlet chamber 16 that metal partion (metp) separates.27.5 armouring cabinet overall dimension is that 900(is loose) * the 2400(height) * 2600(is dark).
As shown in Figures 1 and 2, the valve plate 18 on the one pole valve mechanism 6 moves to the process of service position from disconnection/test position at handcart and opens automatically, closes automatically when handcart moves in the other direction, forms effectively and isolates.
As shown in Figure 1, circuit breaker cart 4 is when the service position, and secondary plug 2 is lockable and can not pulls out.
As shown in Figures 1 and 2, have only when one pole earthed switch 10 is in gate-dividing state, circuit breaker cart 4 could move to the service position from disconnection/test position, only when circuit breaker cart 4 is in disconnection/test position, one pole earthed switch 10 just can carry out closing operation, has realized preventing charged mistake splice grafting ground switch like this.
As shown in Figure 5, this sealing switch equipment can realize closing branch, the combined floodgate that reaches urgent separating brake and earthed switch 10 that move of door operation circuit breaker cart 4.
Realize that the function operations mode is:
When circuit breaker cart 4 gate-dividing states from the experiment position to the progradation of service position, push rod 25 on the circuit breaker cart promotes four connecting rods 19 of one pole valve mechanism 6, four connecting rods 19 drive valve plates 18 and open up and down, and four connecting rods 19 also drive jam plate 3 and clockwise rotate and block secondary plug 2 and make it and can not be pulled out simultaneously; Jam plate 3 rotates counterclockwise when circuit breaker cart 4 valve plate 18 when opposite direction is mobile is closed simultaneously.
After one pole earthed switch 10 closed a floodgate, ground connection dead bolt 23 stretched out and blocks circuit breaker cart 4 and make it and can not advance, on the contrary behind one pole earthed switch 10 separating brakes, 23 indentations of ground connection dead bolt, circuit breaker cart 4 could advance.
Ground connection pin 24 when circuit breaker 4 closes a floodgate in the drive propulsive mechanism 17 stretches out the bottom of blocking ground connection dead bolt 23 can not close a floodgate one pole earthed switch 10; Otherwise earthed switch 10 could close a floodgate.
When cabinet 1 sealing, can move by forward operation hole 20 operating breaker handcarts 4; Make breaker open operation by urgent sub-switching operation hole 21; By ground connection handle hole 22 operation one pole earthed switches 10 minutes, combined floodgate.
