Description

Technical Field

[0001] The invention relates to the technical field of horizontal rotary isolating switch adjustment, in particular to an auxiliary positioning device for adjusting a horizontal rotary isolating switch. Background Art

[0002] The horizontal rotary disconnector is a device used in power systems to isolate power, switch off, and connect and disconnect low-current circuits. It includes ABC three-phase disconnectors and an adjustment drive mechanism. Each set of disconnectors includes a base, an active pole and a driven pole. The active pole and the driven pole are rotatably connected to the base. The operator synchronously controls the opening and closing of the ABC three-phase disconnectors by adjusting the drive mechanism. Figure 1 and Figure 2 The active pole includes an active pole insulator 21 and an active conductive arm 22 fixed at the upper end of the active pole insulator 21; the driven pole includes a driven pole insulator 23 and a driven conductive arm 24 fixed at the upper end of the driven pole insulator 23; a contact is arranged at one end of the driven conductive arm 24 close to the active conductive arm 22, and a contact groove for the contact to enter is arranged at one end of the active conductive arm 22 close to the driven conductive arm 24, and inner contact fingers and outer contact fingers are arranged on two vertical side walls of the contact groove respectively; when the driven conductive arm 24 and the active conductive arm 22 are adjusted to the right position, that is, when the switch is in place, the contact contacts the inner contact fingers and the outer contact fingers at the same time; when the driven conductive arm 24 and the active conductive arm 22 are not adjusted to the right position, the contact contacts the inner contact fingers or the outer contact fingers, so the conductive effect is not good.

[0003] Generally, when making adjustments, the naked eye is used to observe whether the adjustments are in place. This is inconvenient and has large observation errors. In a single adjustment, there are two types of inadequate adjustments, namely over-adjustment and under-adjustment, which require multiple adjustments, increase the adjustment time, and reduce the adjustment efficiency. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a horizontal rotary isolation switch adjustment auxiliary positioning device, which has the advantage of saving adjustment time.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A horizontal rotary isolating switch adjustment auxiliary positioning device comprises a light signal emitting unit and a light signal receiving unit; one of the light signal emitting unit and the light signal receiving unit is installed on the active conductive arm of the isolating switch, and the other is installed on the driven conductive arm of the isolating switch; the light signal emitting unit and the light signal receiving unit are both detachably connected through a fixing piece; when the light signal receiving unit receives the light emitted by the light signal emitting unit, it sends a signal to remind the active conductive arm and the driven conductive arm to adjust into place.

[0007] By adopting the above technical solution, during the adjustment process, the active conductive arm and the driven conductive arm rotate synchronously and approach each other, so that the light signal emitting unit and the light signal receiving unit are gradually opposite to each other. When the light signal receiving unit receives the light from the light signal emitting unit and sends a signal, it indicates that the adjustment is in place, that is, the switch is in place. This avoids the problem of repeated adjustment caused by over-adjustment and under-adjustment in a single adjustment, greatly saves adjustment time, and improves work efficiency and progress. The light signal emitting unit and the light signal receiving unit are both detachably connected by fixings, which is convenient for subsequent maintenance or replacement.

[0008] Optionally, the adjustment deviation of both the active conductive arm and the driven conductive arm is within ±1°.

[0009] By adopting the above technical solution, the adjustment deviation of the active conductive arm and the driven conductive arm is within ±1°, which better meets the adjustment requirements.

[0010] Optionally, the light signal emitting unit is a laser emitting unit; and the light signal receiving unit is a laser receiving unit.

[0011] By adopting the above technical solution, laser is used as the signal medium, the divergence angle of the laser beam is very small, the directionality is very good, and it can be focused on a very small point, thereby improving the accuracy of the adjustment display.

[0012] Optionally, the light signal emitting unit is an infrared emitting unit; and the light signal receiving unit is an infrared receiving unit.

[0013] By adopting the above technical solution, the directionality of infrared is not as strong as that of laser, but it can also meet the needs of adjustment and monitoring. At the same time, because the energy contained in infrared is less than that of laser, it is safer than laser and avoids damage to other components.

[0014] Optionally, the fixing piece is a self-locking plastic cable tie or an externally threaded volute magnetic chuck.

[0015] By adopting the above technical scheme, the optical signal transmitting unit and the optical signal receiving unit are installed with a self-locking plastic cable tie or an externally threaded volute magnetic suction cup, which is simple to operate. The fixing strength of the self-locking plastic cable tie is not as strong as that of the externally threaded volute magnetic suction cup, but it does not require processing of threaded holes and is simple to operate. The fixing strength of the externally threaded volute magnetic suction cup is greater than that of the self-locking plastic cable tie, and can withstand a higher workpiece mass.

[0016] Optionally, the light signal receiving unit includes a signal module; the signal module sends a signal to indicate that the active conductive arm and the driven conductive arm are adjusted into place.

[0017] By adopting the above technical solution, the existence of the signal module can enable the operator to know that the adjustment is in place at the first time, thereby further improving the operating efficiency.

[0018] Optionally, the signal module uses an LED indicator light; when the active conductive arm and the driven conductive arm are adjusted into place, the LED indicator light is on.

[0019] By adopting the above technical solutions, LED indicator lights are energy-saving and have excellent performance in terms of brightness, efficiency, life, startup time, response speed and color characteristics. Its high luminous efficiency and adjustable brightness meet the indication needs of different scenarios, its long life reduces maintenance costs and replacement frequency, its fast startup and response can accurately and timely convey indication information, and its precise color control realizes diversified indication functions.

[0020] Optionally, the light signal emitting unit and the light signal receiving unit both have a power supply module; the power supply module uses a dry cell battery.

[0021] By adopting the above technical solution, the existence of the power supply module ensures the working stability and continuity of the light signal transmitting unit and the light signal receiving unit. In addition, the dry battery is small and light, easy to carry, has a long storage life, and has a smaller voltage change rate, and can be placed for a long time without losing too much power.

[0031] The following is combined with Figure 1-Figure 6 The present invention is described in further detail.

[0032] Embodiment 1: A horizontal rotary isolation switch coordination auxiliary positioning device is disclosed, wherein reference Figure 1 The horizontal rotary isolating switch 20 is fixed on the top of the bracket 10. The horizontal rotary isolating switch 20 is a prior art. The horizontal rotary isolating switch 20 has three groups of isolating switches of three phases ABC and an adjusting driving mechanism for synchronously adjusting the three groups of isolating switches. Figure 2 Each set of isolating switches includes an active pole and a driven pole rotatably connected to the base, the active pole includes an active pole insulator 21 and an active conductive arm 22 fixed at the upper end of the active pole insulator 21; the driven pole includes a driven pole insulator 23 and a driven conductive arm 24 fixed at the upper end of the driven pole insulator 23; the operator operates and adjusts the driving mechanism to make the active conductive arms 22 and the driven conductive arms 24 of the three sets of isolating switches rotate synchronously to approach or move away. When the active conductive arm 22 and the driven conductive arm 24 approach each other, the contact of the driven conductive arm 24 enters the contact slot of the active conductive arm 22 to contact with the inner contact finger and the outer contact finger of the contact slot to complete the closing; when the active conductive arm 22 and the driven conductive arm 24 move away from each other, the contact of the driven conductive arm 24 leaves the contact slot of the active conductive arm 22. The adjustment of the horizontal rotary disconnector is the adjustment of the driven conductive arm 24 and the active conductive arm 22, specifically, the contact of the driven conductive arm 24 entering the contact groove of the active conductive arm 22, and the position adjustment of the inner contact finger and the outer contact finger.

[0033] refer to Figure 2-Figure 5The joint adjustment auxiliary positioning device includes a laser emitting unit 25 and a laser receiving unit 26; the laser emitting unit 25 is fixed on the active conductive arm 22, and the direction of the laser emitted by the laser emitting unit 25 is parallel to the length direction of the active conductive arm 22; the laser receiving unit 26 is fixed on the driven conductive arm 24; during the adjustment process of the horizontal rotary disconnector, the laser emitting unit 25 gradually changes from a direction deviating from the laser receiving unit 26 to a direction close to the laser receiving unit 26; when the laser emitted by the laser emitting unit 25 is emitted to the laser receiving unit 26, the horizontal rotary disconnector is adjusted to the right position, at which time the length directions of the active conductive arm 22 and the driven conductive arm 24 are in the same direction; generally, the adjustment deviation of the active conductive arm 22 and the driven conductive arm 24 is within ±1°, that is, the laser emitted by the laser emitting unit 25 is facing the laser receiving unit 26 to be adjusted to the best position, and within the ±1° angle range on this basis, the laser receiving unit 26 can only receive the laser emitted by the laser emitting unit 25 within the above-mentioned angle range, and at this time, as long as the laser receiving unit 26 receives the laser emitted by the laser emitting unit 25, it indicates that the horizontal rotary disconnector is adjusted to the right position. In other embodiments, the laser emitting unit 25 may be fixed on the driven conductive arm 24, and the laser receiving unit 26 may be fixed on the active conductive arm 22.

[0034] The laser emitting unit includes a laser emitting module, a power driving module and a laser power supply module; the laser emitting module is a NT64600 laser generator; the power driving module is a lm2596 power chip; and the laser power supply module is a dry cell battery.

[0035] The laser receiving unit includes a laser receiving module, a DC voltage conversion module, a CPU module, a signal module and a laser power supply module; the laser receiving module is an HD-1-3 laser receiving unit, the DC voltage conversion module is an ME7660CS1G DC voltage conversion module; the CPU module is a PIC16F1827 module; the signal module is an LED indicator light; and the laser power supply module is a dry battery.

[0036] refer to Figure 6 When the laser receiving unit 26 receives the light signal emitted by the laser emitting unit 25, it indicates that the active conductive arm 22 and the driven conductive arm 24 are adjusted to the right position. Figure 3 At this time, the signal module of the laser receiving unit sends a corresponding signal. If the signal module is an LED indicator, when the active conductive arm 22 and the driven conductive arm 24 are adjusted to the right position, the LED indicator will light up, so that the operator can know the adjustment is in place at the first time, that is, the closing is in place, so there will be no Figure 4 The under-adjustment and Figure 5 The over-regulation situation can be eliminated, thereby reducing the regulation time and improving the regulation efficiency.

[0037] For easy disassembly and assembly, the laser emitting unit 25 and the laser receiving unit 26 can be detachably connected through a fixing piece. In combination with actual operation, the fixing piece can be fixed with a self-locking plastic cable tie or an externally threaded volute magnetic suction cup; the self-locking plastic cable tie is easy to operate and has low cost; since the externally threaded volute magnetic suction cup has a screw, it is necessary to machine corresponding threaded holes on the active conductive arm 22 and the driven conductive arm 24, but the weight of the workpiece that the externally threaded volute magnetic suction cup can bear is much greater than that of the self-locking plastic cable tie, which is beneficial to the position stability of the laser emitting unit and the laser receiving unit, thereby improving the subsequent adjustment accuracy.

[0038] Embodiment 2: Embodiment 2 differs from Embodiment 1 in that: the laser emitting unit 25 is replaced by an infrared emitting unit, and the laser receiving unit 26 is replaced by an infrared receiving unit. In this way, when working, the laser light signal is replaced by an infrared light signal. Since the energy contained in infrared rays is less than that contained in laser rays, it is safer to use. Therefore, in theory, similar light signals can be used, but their divergence angles must meet the design size to ensure the accuracy of signal transmission.

[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
