Description

Technical Field

[0001] The invention relates to the technical field of isolating switches, and in particular to a closed ice-melting isolating switch. Background Art

[0002] The isolating switch is a switching device that is mainly used to isolate power supply, switch operation, connect and disconnect small current circuits, and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when it is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage of more than 1kV. Its working principle and structure are relatively simple, but due to its large usage and high working reliability requirements, it has a great impact on the design, construction and safe operation of substations and power plants. The main feature of the isolating switch is that it has no arc extinguishing ability and can only open and close the circuit without load current. The entry introduces the functions, characteristics, types, applications, error prevention improvements, maintenance, common problems, etc. of the isolating switch.

[0003] Because the isolating switch is exposed to the environment, when it encounters rain or snow in cold weather, ice will appear on the outer wall of the isolating switch. In particular, ice on the contact head and isolating knife switch will cause the equipment to be unable to open and close normally, thereby interfering with the normal operation of the power grid system. At the same time, ice on the insulator will also reduce the insulation level, causing flashover grounding accidents, and even burn out the insulator, causing losses.

[0004] The structure of the existing ice-melting isolating switch has the following shortcomings: Usually, a set of high-voltage horizontal opening disconnectors is added between the de-icing pipe bus and the high-voltage outgoing line. One end of the disconnector is connected to the DC de-icing bus, and the other end is connected to the high-voltage transmission line. Due to the large size of the horizontal opening disconnector equipment, it is generally necessary to open up a relatively large site, which increases the floor area and increases the investment.

[0005] It is impossible to wrap and seal the entire switch synchronously when closing the circuit breaker, so the heat generated by heating the ice melting is easily lost, which reduces the ice melting efficiency. Summary of the invention

[0018] The present invention, through the design of the controller, the switch body, the driving mechanism and the ice-melting mechanism, can drive the two sealing shells to approach each other when the isolating knife switch is closed until they are tightly connected, and can seal the isolating switch body in a wrapped state.

When the ice on the switch body is heated, it melts into water and then drips from the outer wall of the switch body to the top of the bottom plate and is discharged from the plurality of V-shaped drainage grooves. The V-shaped drainage grooves are wide at the top and narrow at the bottom. The wider top facilitates the outflow of melted ice water, while the narrower bottom prevents the loss of heat generated during heating to the greatest extent, thereby ensuring the ice melting effect.

Even after the two sealing shells are docked, the lines will not be damaged, thereby improving the safety of ice melting and avoiding losses. BRIEF DESCRIPTION OF THE DRAWINGS

The wider top facilitates the outflow of melted ice water, while the narrower bottom prevents the loss of heat generated during heating to the greatest extent, thereby ensuring the ice melting effect.

[0037] The working principle of the present invention is as follows: when ice melting is required, the motor 22 is started through the controller, so that its output end drives the worm 23 to rotate. Since the worm wheel 24 is fixedly connected to one end of the first rotating shaft 13, the worm 23 is meshingly connected with the worm wheel 24, and the isolating knife switch 19 and the ends of the two rocker arms 14 away from the first rotating shaft 13 are respectively hinged to the two ends of the insulating pull rod 18, and the isolating knife switch 19 is hinged to one of the terminal blocks 20, thereby driving the isolating knife switch 19 to rotate toward the end close to the second contact head 17.

[0040] When the second rotating shaft 28 rotates clockwise, since the two adapter blocks 27 are fixedly connected to the inner wall of one of the sealed shells 15, the turntable 25 is fixedly connected to one of the L-shaped rods through the second rotating shaft 28, the top of the mounting block is fixedly connected to the two L-shaped rods, the turntable 25 and the two adapter blocks 27 are respectively hinged to the two ends of the connecting rod 26, thereby driving one of the sealed shells 15 to slide toward the end close to the isolating switch.

[0041] When the second rotating shaft 28 rotates clockwise to drive one of the sealed shells 15 to slide toward one end close to the isolating switch, since the two second synchronous wheels 36 are respectively fixedly connected to the second hinge shaft and one of the second rotating shafts 28, the second synchronous belt 35 is sleeved between the two second synchronous wheels 36, the second hinge shaft is rotatably connected to another L-shaped rod, the first gear 33 and the second gear 34 are respectively fixedly connected to the second hinge shaft and the other second rotating shaft 28, the first gear 33 and the second gear 34 are meshedly connected, and then the other turntable 25 rotates counterclockwise, thereby driving the other sealed shell 15 to slide toward the mounting block through another connecting rod 26 and the two adapter blocks 27, and then the two sealed shells 15 are close to each other.

[0042] Since the sensing rod 38 and the proximity sensor 39 are respectively fixedly designed at one adjacent end of the two sealed shells 15, and the axial directions of the sensing rod 38 and the proximity sensor 39 are consistent, when the two sealed shells 15 approach each other until they are close to each other, the proximity sensor 39 can detect the arrival of the sensing rod 38 and send the information that the two sealed shells 15 are tightly joined to the controller.

[0043] When the information that the two sealed shells 15 are tightly joined is sent to the controller, the controller starts several electric heating plates 37. Since the several electric heating plates 37 are respectively fixed on the inner top and the inner side wall of the sealed shell 15, they cooperate with another heating component. After the two are tightly joined, the switch body 12 located inside the two sealed shells 15 is heated in multiple directions, so that all ice on the outer wall of the switch body 12 is effectively heated, which is beneficial to improve the ice melting effect and ensure the normal separation and combination of the equipment, thereby ensuring the normal operation of the power grid system, and preventing the insulators from being covered with ice and reducing the insulation level, causing flashover grounding accidents, and even burning the insulators and causing losses.

[0044] When the ice on the switch body 12 is heated, it melts into water and then drips from the outer wall of the switch body 12 to the top of the bottom plate 11, and is discharged from a plurality of V-shaped drainage grooves 41. The V-shaped drainage grooves 41 are wide at the top and narrow at the bottom. The wider top facilitates the flow of melted ice water, while the narrower bottom prevents the loss of heat generated during heating to the greatest extent, thereby ensuring the ice melting effect.

[0045] The four semicircular wiring holes 40 become two circular holes after the two sealing shells 15 are docked, so it is convenient to connect the two wiring boards 20 to other power equipment. Even after the two sealing shells 15 are docked, the lines will not be damaged, which improves the safety of ice melting and avoids losses.
