专利说明:
The invention relates to a disconnector for high-voltage installations with a metal grounded Kopnyco filled insulating medium with high penetration strength and with empty contact elements. Known disconnector for high-voltage installations, containing a metal grounded housing, filled with an insulating medium with high penetration strength, two hollow contact elements, one of which contains a spring-loaded breaking pin OJ i One: a well-known disconnector is able to switch small loads with small disconnectors in the metal The casing with compressed gas is economically performed with relatively slow drive of the contact elements. Therefore, they do not switch as much as possible under load, since when an electric arc arises due to slow switching off, there is a danger that, in particular, at higher nominal voltages, the electric arc will go beyond, transfer to a grounded metal case and form a short circuit to the earth. The purpose of the invention is to exclude damages caused by the appearance of an electric arc. The goal is achieved. The disconnector is equipped with screens with contact elements inside, a notch is made at the end of the discontinuous contact pin, another contact element is equipped with a manual latch that engages with a recess in the position of disconnected contact pin and the latch has a control mechanism . . The control mechanism includes a cylinder, in which a piston is mounted with a possibility of sliding, on which a mechanical arm is installed, which is spring-loaded against the cylinder walls, the latter is installed inside the screen. The latch control mechanism is provided with a stop mounted on the wall of the cylinder. The latch is made in the form of a crank lever, which is installed with the possibility of rotation around the psychic attachment. The latch is designed as a collet. FIG. 1 shows a disconnector, disconnected position; FIG. 2 on position} in FIG. 3 and 4 are different positions for releasing the rupture contact pin on | u. 5 and 6 are structurally different implementation examples. Disconnector 1 is located in a tubular metal grounded housing 2, which is closed from the end sides by conical bushing insulators 3, which carry the tubular conductor 4 placed in the middle. The housing 2 is filled with hexafluoric sulfur under elevated pressure. In order to align the electric field between the grounded housing 2 and the hollow contact elements 5 and 6, both the mobile contact element 5 and the fixed contact element 6 are enclosed by shields 7. A drive 8 for moving contact element 5 is also placed inside shield 7. Inside moving contact element 5 there is a breaking pin 9, in which a recess 10 is provided, formed by a groove of a smaller diameter. The tear pin has a pin 9 held in place. the rest position is spring 11. In this position, it is completely covered by the movable contact element 5 and does not go beyond its limits. Inside the counter-mounted screen 7 with a fixed contact element 6 there is provided a cylinder 12 in which piston 13 runs. This piston 13 carries a pawl 15 rotating in a bearing 14 consisting of a crank lever and moving into a hook 16. The latch 15 is also held in a rest position spring 17 so that in the open position it does not extend beyond the fixed contact element 6. Next, another return spring 18 is provided between the piston 13 and the latch 15, which delays the latch 15 after its rotation again in position peace of mind. The short shoulder 19 of the lever next to the bearing 14 passes and protrudes through the slot in the cylinder 12. On a possible path of its course there is a rearranging and fixed stop 20, which by means of the shoulder 19 pbpjara causes the latch 15. 15. In FIG. Figure 1 shows the disconnected position of the disconnector 1, in which the tensile contact pin 9 with the movable contact element 5, as well as the latch 15 are in the resting position. On .fig. Figure 2 shows the on position of the disconnector 1. In the on position, the movable contact element 5 is engaged with the stationary contact element 6. The latch 15 is still in the end position, but it goes inside the hollow movable contact element 5 and with its hook (16 captures the notch 10 contact pin 9, so that in addition to the main current path from conductor 4 through the movable contact element 5, the fixed contact element 6, the shield 7 to the conductor 4 forms an auxiliary current path of black The disconnecting pin 9 and the latch 15. When disconnecting the connector 1 (Fig. 3 or 4), the slow moving actuator 8 first moves the hollow movable contact element 5 backward only to break its connection with the fixed contact element. 6 and form a sufficiently large distance The fracture contact pin 9 remains in engagement with the latch 15, so that the current that is possibly present only flows along the auxiliary path. Due to the opening movement of the spring 11, acting on the tensile contact pin 9, the tension is the same as the spring 17 of the latch 15, since the latch 15 is gripped by the breaking pin 9 until the shoulder of the lever 19 rests against the stop 20. It acts on a pivotal movement of the latch 15, due to which the hook 16 extends from the recess 10 into the rupture pin 9 and releases it. Due to the tension springs 11 and 17, the latch 15 and the breaking pin 9 move from each other at a speed many times higher than the speed of movement of the movable contact element 5, so that the resulting electrical arcs between the latch 15 and the breaking pin 9 quickly quench. The moment of release of the discontinuous end 39 .4 of the latch pin 9 with the latch .15 can be quite accurately determined by installing the stop 20. In the example shown in FIG. 3, the position of the stop 20, the latch 15 is in the position of a moment, still released within the limits of the screen 7. On the contrary, in the position of the stop 20 shown in FIG. 4, the latch 15 is already pulled out by the discontinuous contact pin 9 to the free rupture area contact pin 9. The return spring 18 returns the latch 15 after its rotation again back to the rest position. FIG. 5 shows a slightly modified example of one-piece of connector 1, the same numerical designations are kept for identical parts. Here the breaking pin 9 with its spring 11 is installed in the cylinder 12 in the screen 7 of the fixed contact element 6. The latch 15, on the contrary, together with; return spring 18, is installed inside the movable contact element 5 stationary, but can be rotated in the bearing 14. And here the angular shoulder 19 extends out through the slot in the hollow movable contact element 5, so that during the shutdown movement abuts against the stop 20 inside the screen 7 and this acquires a pivotal motion, releasing the breaking pin 9. FIG. 6 shows again the latch 15 inside the screen 7 enclosing the stationary contact element. It is mounted on the piston 13 sliding in the cylinder 12 so that the spindle rotates in the bearing 14. The latch 15 is provided with two levers of the collet 21 and 22, between which there is a return spring 18 It is also loaded with a spring 17. When the disconnector 1 is turned on, both of the collet levers 21 and 22 enter on you from both sides. The capacitor 10 of the discontinuous contact pin 9. This improves the mechanical connection between the disposable contact pin 9 and the latch 15. And here each collet lever passes into the shoulders of the lever 23 and 24, which, respectively, abut against the lugs 20, when release of the discontinuous is reached contact pin 9. j "N" / T 6
