Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnetic column switches, in particular to an improved permanent magnetic column switch. Background Art

[0002] A pole switch is a type of safety switch used on utility poles to ensure the safety of electricity use. Its main function is to isolate circuit faults. There are various forms of pole switches on the market with different performances. They can be classified into the following six methods: ① According to the country of production, they can be divided into domestic and imported types; ② According to the arc extinguishing ability of the contacts, they can be divided into circuit breakers; ③ According to the insulating medium, they can be divided into oil insulation, air insulation, and SF6 insulation; ④ According to the operating mechanism, they can be divided into electromagnetic operating mechanism, spring operating mechanism, and permanent magnet operating mechanism; ⑤ According to the function of the controller, they can be divided into circuit breakers, reclosers, and sectionalizers; ⑥ According to the material of the outlet bushing, they can be divided into porcelain bushings and silicone rubber bushings, etc.

[0003] The switches currently on the market have the following problems during use:

[0004] 1. When the outdoor power supply is lost, the single permanent magnet structure switch cannot be closed locally, which affects the convenience of use in certain circumstances;

[0005] 2. The problem of matching and adjusting the double rigid closing points of the permanent magnet plus spring-operated structure switch. For this type of structure, the switch has high requirements for the coordination of the front and rear positions of the terminal closing point. The terminal closing point of the permanent magnet mechanism should be 0.5 to 1.5 mm ahead of the terminal closing point of the spring mechanism, so that the characteristics of the two mechanisms can be well matched. The actual structural form and other structural settings make it difficult to achieve precise position limitation, resulting in unreasonable matching of the position points between the two, which seriously affects the closing retention of the permanent magnet mechanism and the service life of the permanent magnet mechanism.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0043] The release pin 3-6 of the spring-operated release mechanism is non-fixedly connected and fitted with the release plate of the auxiliary spring operating mechanism 1-9.

[0044] The coordination problem between the auxiliary spring mechanism and the main transmission shaft of the switch with permanent magnet plus spring-operated structure. The existing auxiliary spring operating mechanism adopts a rigid transmission structure with no idle stroke. For this type of connection, the crank arm of the auxiliary spring-operated mechanism is in the closing and holding position each time the switch is closed. Therefore, each opening operation requires the spring-operated opening coil to synchronously participate in the opening operation. If the opening coil of the spring-operated mechanism is damaged during the movement, the permanent magnet mechanism will not be able to open the switch.

[0045] Specific action principle:

[0046] Electric closing operation of the switch: The switch transmission mechanism box 1-3 secondary control and the signal interface 1-4 provide an electrical signal to drive the permanent magnet mechanism 1-18 and the permanent magnet mechanism output transmission pin 2-8 to drive the switch transmission main shaft 1-16 to move, and then drive the transmission connecting rod 2-5, the pull rod connecting rod 2-4, the overtravel spring pressure rod 2-3, the insulating pull rod 2-1 and other movements in turn to realize the closing operation of the switch;

[0047] Electric opening operation of the switch: The switch transmission mechanism box 1-3 secondary control and the signal interface 1-4 give an electrical signal to drive the permanent magnet mechanism 1-18. The permanent magnet mechanism output transmission pin 2-8 drives the switch transmission main shaft 1-16 to move, and then drives the transmission connecting rod 2-5, the pull rod connecting rod 2-4, the overtravel spring pressure rod 2-3, the insulating pull rod 2-1 and other movements in turn to realize the opening operation of the switch.

[0048] Manual closing and opening operation of the switch:

[0049] a Manual closing operation: The switch transmission mechanism box 1-3 manual closing handle and the transmission shaft 1-5 provide an electrical signal or manual energy storage operation to drive the auxiliary spring mechanism output transmission pin 2-6 of the auxiliary spring operating mechanism 1-9 to move, and then drive the transmission connecting rod 2-5, the pull rod connecting rod 2-4, the overtravel spring pressure rod 2-3, the insulating pull rod 2-1, etc. to move in turn to realize the closing operation of the switch;

[0050] b. Manual tripping operation: through the manual tripping handle of the switch transmission mechanism box 1-3 and the transmission shaft 1-7, one way drives the tripping roller 2-9, and the driving tripping roller 2-9 connected to the transmission connecting rod 2-5 to realize the manual tripping of the permanent magnet mechanism, and the other way pulls the synchronous tripping transmission connecting rod 3-7 through the manual tripping welding crank arm 1-14, and drives the linkage tripping mechanism driving connecting plate 3-1 and the elastic tripping mechanism transmission shaft 3-4, elastic tripping mechanism tripping plate 3-5, and elastic tripping mechanism tripping pin shaft 3-6 that are synchronously connected and move, and pushes the tripping device of the auxiliary spring operating mechanism 1-9 to realize the tripping of the elastic operating mechanism;

[0051] Fine-tuning principle of dual rigidity points of dual mechanisms: dual mechanisms each have a rigidity point. Since the auxiliary spring operating mechanism is an auxiliary mechanism and considering the particularity of the permanent magnet mechanism, the rigidity point of the spring operating mechanism lags behind the rigidity point of the permanent magnet mechanism by 0.5 to 1.5 mm. By fine-tuning the relative position between the output rod 2-10 of the permanent magnet mechanism 1-18 and the adjustable output block 2-12, the rigidity points of the dual mechanisms can be adjusted without disassembling other parts.

[0052] The principle of only putting the permanent magnet mechanism into operation in the dual-mechanism electric scheme is as follows: a long waist-shaped hole is provided in the transmission pin matching hole of the auxiliary spring operating mechanism 1-9 of the switch transmission main shaft 1-16, so that the auxiliary spring operating mechanism 1-9 only plays a driving role in the closing process and is not put into operation in the opening process. During the driving process of the permanent magnet mechanism, the auxiliary spring operating mechanism 1-9 is kept in an invalid position due to the spring reaction force of the closing holding mechanism of the auxiliary spring operating mechanism 1-9 itself, thus realizing the principle that only the permanent magnet single mechanism is put into operation under the electric working condition;

[0053] Adjustment of manual synchronous tripping: By adjusting the limit pin 3-2 of the spring-operated tripping mechanism, the synchronization problem of the tripping mechanism is achieved. At the same time, the tripping pin shaft 3-6 of the spring-operated tripping mechanism and the tripping plate 1-9 of the auxiliary spring operating mechanism are in non-fixed connection and fit contact, which greatly simplifies the process performance of the transfer.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
