As shown in fig. 1, the general overhaul platform of the pincer-clamp type disconnecting switch includes an isolating switch fixing platform 100, a vertical isolating switch testing system 200 and a horizontal isolating switch testing system 300;
the vertical isolating switch testing system 200 comprises a rotating rod 210, a first clamping force testing rod 220 and a first loop resistance testing rod 230, wherein the rotating rod 210 is vertically arranged on the isolating switch fixing platform 100, and the first clamping force testing rod 220 and the first loop resistance testing rod 230 are arranged at the upper end of the rotating rod 210 and can rotate along with the rotating rod 210;
the lateral isolator testing system 300 includes a rotary base 330 disposed at one side of the isolator fixing stage 100, and the rotary base 330 is provided with a second clamping force testing rod 340 and a second loop resistance testing rod 350 which rotate with the rotary base 330.
As shown in fig. 2, the present embodiment takes test GW16 type isolation switch 800 and GW17 type isolation switch 700 as examples for explanation:
when testing is carried out on the GW16 type disconnecting switch 800, the GW16 type disconnecting switch 800 is vertically and fixedly connected to the disconnecting switch fixing platform 100, the clamp type disconnecting switch of the GW16 type disconnecting switch 800 faces the testing rod arranged at the upper end of the rotating rod 210, and when the clamping force needs to be tested, the rotating rod 210 rotates, so that the first clamping force testing rod 220 enters the clamping position of the disconnecting switch to carry out the test of the clamping force; when the loop resistance test is performed, the rotating rod 210 rotates, so that the first loop resistance test rod 230 enters the clamping position of the knife switch to perform the loop resistance test.
When testing the GW17 type disconnector 700, the GW17 type disconnector 700 is laterally fixed to the disconnector fixing platform 100, and the clamp-type knife switch of the GW17 type disconnector faces the testing rod provided on the rotating base 330. When the clamping force needs to be tested, the rotating base 330 rotates, so that the second clamping force testing rod 340 enters the clamping position of the knife switch to test the clamping force; when the loop resistance test is performed, the rotary base 330 rotates, so that the second loop resistance test rod 350 enters the clamping position of the knife switch to perform the loop resistance test.
The application can be compatible with the test requirements of the clamp-type disconnecting switch such as GW6, GW16 and GW17, the integration level of the maintenance device is improved, and the equipment cost of the maintenance tool is reduced. And the clamping force testing rod and the loop resistance testing rod are independently arranged, so that the testing condition can be truly simulated, and the accuracy of the testing result is ensured.
As shown in fig. 3 to 5, the rotating rod 210 includes a worm 211, a worm receiving support rod 212, and a rotating worm wheel 213, the worm 211 and the worm receiving support rod 212 are disposed vertically, the worm 211 is rotatably disposed in the worm receiving support rod 212, the rotating worm wheel 213 is sleeved on the worm 211, a key slot 2111 penetrating the length of the worm is disposed on a shaft of the worm 211, a key 2131 matched with the key slot 2111 is disposed in the rotating worm wheel 213, and the rotating worm wheel 213 is in transmission connection with the rotating motor 410 to drive the rotating worm wheel 213 to rotate.
When the rotating motor 410 is started, the motor transmits torque to the rotating turbine 213 through a transmission mechanism such as a secondary reduction gearbox, and the rotating turbine 213 rotates together with the worm 211 due to the connection of the key of the rotating turbine 213 and the key groove of the worm 211, so that the rotation switching action of the top first clamping force testing rod 220 and the first loop resistance testing rod 230 is completed.
Due to the fact that the switch-on heights of the isolating switches of various models are different, the heights of the testing rods need to be adjusted adaptively according to the switch-on heights of the switches of different models and voltage levels.
As shown in fig. 3, 4 and 6, the rotating rod 210 is further sleeved with a lifting worm gear 214, an internal thread matching with the worm 211 is arranged in the lifting worm gear 214, and the lifting worm gear 214 is in transmission connection with a lifting motor 420 to drive the lifting worm gear 214 to rotate.
When the lifting motor 420 is started, the motor transmits torque to the lifting turbine 214 through a transmission device such as a primary reduction gearbox to drive the lifting turbine 214 to rotate, and the rotation of the lifting turbine 214 causes the worm 211 to move in the vertical direction due to the fixed vertical position of the lifting turbine 214, so that the actions of lifting the first clamping force testing rod 220 and the first loop resistance testing rod 230 at the top to adjust the testing height are completed.
It should be noted that, when the rotary worm wheel 213 rotates, since the lifting worm wheel 214 is also on the worm 211 at this time, the rotary motion of the worm 211 will cause the worm 211 to still have a certain lifting motion, but since the rotary motion is controlled at most at 180 °, the lifting height of the worm 211 at this time is at most half of the screw lead, and the pincer-like disconnector has a reasonable range for the switching-on position, and the change in the lifting height of the worm 211 at this time is far enough to make the switching-on position deviate from the switching-on reasonable position range, so the height error can be regarded as having no influence.
In order to protect the rotating turbine 213 and the lifting turbine 214 and the corresponding transmission parts, a protective box 500 is arranged around the rotating turbine 213 and the lifting turbine 214, and is covered therein for protection.
As shown in fig. 3, the fixing frame 240 is radial and includes a middle fixing member 241 and an even number of connecting rods 242 connected to the fixing member 241, the fixing member 241 is connected to the top end of the worm 211, and the tail end of each connecting rod 242 suspends the first clamping force testing rod 220 or the first loop resistance testing rod 230 of each voltage class.
The fixing frame 240 can be provided with a plurality of sets of connecting rods 242, so that different types of sets of the first clamping force testing rod 220 and the first loop resistance testing rod 230 can be installed. The number of the connecting rods 242 in this embodiment is four, and the first clamping force testing rod 220 and the first loop resistance testing rod 230 for two voltage levels of the GW16 type disconnecting switch and the GW6 type disconnecting switch are connected to the connecting rods, respectively.
Through the connecting rod 242 that sets up the even number, when testing GW16 type isolator or GW6 type isolator's different voltage class model, can need not change first clamp force test bar 220 and first return circuit resistance test bar 230, only need rotate to correspond required test bar can to the change problem that the isolator of solving different voltage class models needs the test bar of different centre gripping diameters.
The isolating switch device further comprises a rotating base transverse moving device, wherein the rotating base transverse moving device comprises a guide rail 310 connected to one side of the isolating switch fixing platform 100 and a moving platform 320 arranged on the guide rail 310, and the bottom of the rotating base 330 is fixedly connected to the moving platform 320.
The entire moving platform 320 can slide on the guide rail 310 to adjust the closing test distance of the GW17 type isolation switch with different voltage levels.
Further, a moving platform locking mechanism 321 is disposed on the moving platform 320 for fixing the moving platform 320 to prevent the moving platform 320 from moving on the guide rail 310 during the test. According to the parameters to be measured on site, the testing rod can be manually shifted to drive the manual rotating base 330 to rotate, the testing rod is switched, a fixed block is arranged below the manual rotating base, and when the manual rotating base rotates to a proper position, the screw can be screwed down to fix the testing position of the testing rod, so that the testing rod is prevented from deviating from the original proper position due to switching-on operation during testing.
As shown in fig. 7, the disconnecting switch fixing platform 100 includes a supporting platform 110 and a disconnecting switch mounting plate 120, the disconnecting switch mounting plate 120 is fixedly mounted on the supporting platform 110 through a supporting column, and four-direction inclined waist-shaped circular holes 121 are formed in the disconnecting switch mounting plate 120.
The installation position of the isolating switch installation plate 120 adopts four-direction inclined waist-shaped round holes 121, so that various isolating switches can be normally installed on the isolating switch installation plate 120. The front of isolator mounting panel 120 is opened jaggedly, prevents to crush the conductive area during the installation, and isolator mounting panel 120 is connected to supporting platform 110 through four support columns.
Further, the supporting platform 110 is further provided with a disconnecting switch operating force providing device, the disconnecting switch operating force providing device comprises a translation platform 610 and a flange plate 620, the translation platform 610 has a stroke in the same direction as the guide rail 310, and the flange plate 620 is vertically arranged on the translation platform 610.
Because the switching-on length of the GW17 type disconnecting switch is very long, and the variation range of the jaw position is not large when the GW17 type disconnecting switch of each voltage class is switched on, the guide rail 310 does not need to be adjusted by a long stroke, so the extension part of a section of guide rail 310 is connected in front of the supporting platform 110, and the part of the guide rail 310 is shortened as much as possible, so as to reduce the processing of an overlong workpiece as much as possible, improve the strength of the guide rail 310, and reduce the manufacturing difficulty of the equipment parts.
The defects that the traditional overhauling equipment is too large in size, occupies too large space, is low in using frequency of single equipment, and cannot realize electrical control due to errors of detection data after the test rod II and the test rod I are overcome.
In the previous maintenance work, five sets of maintenance equipment are needed for six types of isolating switches including 126KV and 252KV of GW6, GW16 and GW17 (it should be noted that the present invention can be applied to maintenance of the six types of isolating switches, and for most pincer-type isolating switches, only the sizes of the corresponding isolating switch mounting plate 120, the guide rail 310 and the worm 211 need to be adjusted), because the closing positions of GW6 and GW16 isolating switches in a high space, it is difficult to manually switch the test bars, so a two-in-one test bar has to be adopted, which affects the test accuracy. Meanwhile, because the integration level is too low, the average cost for realizing automatic control is too high, the operation force providers of the maintenance equipment are provided by people, the maintenance level is lagged behind, and the mechanism operation force required by the operation of opening and closing can not be detected because the disconnecting switch is manually controlled to open and close.
Vertical isolating switch testing system 200 is adopted for testing GW6 and GW16 isolating switches, all operating forces of switches to be detected are provided, and automatic control is achieved, so that the problems that operating torque cannot be measured and two-in-one testing rods must be adopted are fundamentally solved. The invention is convenient for popularization and application, has low total maintenance cost compared with the prior single maintenance platform, removes the influence of most human factors and equipment factors on the detection result, has higher maintenance precision and occupies smaller total space.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
