Description

Switching-off device of outdoor isolation switch

Technical Field

The utility model relates to an auxiliary switch-off tool, in particular to a switch-off device of an outdoor isolation switch.

Background

The 10kV distribution network is mostly erected by overhead multi-circuit same poles, and switches and isolation switches for circuit breaking, interconnection and branching are installed at multiple positions of a circuit. The equipment of circuit salvagees, maintains, work such as load distribution needs the switching operation that the circuit had a power failure, because urban area road blocks up, generally uses small-size pick up car, adopts single operation line switch and isolation switch on the pole to guarantee safety, quality, the efficiency of work. However, the urban line isolation disconnecting link is installed outdoors and exposed to the sun and rain, and the moving and static contacts of part of the disconnecting link are tightly occluded after being oxidized, so that the line isolation disconnecting link cannot be pulled open by 100% in a mode of operating on a single electric pole, and in the case of the situation, the line isolation disconnecting link needs to be operated by means of an overhead working truck. The overhead working truck belongs to a medium-sized vehicle in an urban area, and is very time-consuming when walking on a congested urban road, and the time of 1 hour or even longer is usually consumed for operating one isolation switch.

Therefore, the operation of the operating vehicle is inconvenient when the isolation switch is opened, but the isolation switch is difficult to open manually due to the fact that the isolation switch is tightly engaged and the single strength is insufficient in manual operation.

Example 1

This embodiment 1 provides an open device of outdoor isolation switch, as shown in fig. 1, fig. 2, including first load pole 1 and second load pole 2, the end connection reinforcing plate 3 of the tip of first load pole 1 and second load pole 2 is provided with the operation hanging hole 5 that can be connected with insulating bar 8 on the reinforcing plate 3, the tip of first load pole 1 be provided with can with switch 10 fixed connection's base 7, the tip of second load pole 2 is provided with the couple 6 that can be connected with switch 10.

The device is used as follows: during one-man operation, install the base 7 of this device one end in one side of switch 10, the one end that is close to the moving contact on the switch 10 has one and hangs and detain 9, the couple 6 that sets up can with hang and detain 9 looks adaptations, couple 6 can directly catch on and hang and detain 9, can insert operation hanging hole 5 with the one end of insulating bar 8, down pull insulating bar 8, the power is used in whole device, couple 6 on the device is withheld and is detained 9, the power is used on hanging detain 9, then can be more light open isolating switch 10.

The working principle of the device is as follows: because the moment is equal to the force multiplied by the moment arm, when a certain moment is needed to open the disconnecting link 10 in a rotating way, the moment arm is increased when the moment is constant, so that the disconnecting link 10 can be opened by using a small force, and the function of saving labor when a single person pulls the disconnecting link 10 is realized.

A reinforcing rod 4 is also arranged between the first bearing rod 1 and the second bearing rod 2. In order to ensure the stability and the bearing capacity of the whole device, the reinforcing rod 4 is arranged, so that the first bearing rod 1 and the second bearing rod 2 can not deform due to overlarge bearing pressure, particularly, when the insulating operating rod 8 is pulled down, the force between the first bearing rod 1 and the second bearing rod 2 is very large, and the reinforcing rod 4 is required to ensure the bearing capacity of the whole device. The reinforcing rod 4 is welded between the first bearing rod 1 and the second bearing rod 2, and mainly plays a role in supporting the two rod pieces, so that the stability of the device in pressure bearing is ensured.

The sides of the first bearing rod 1 and the second bearing rod 2 close to the reinforcing plate 3 are close to each other. Can form a trapezoidal form, perhaps triangle-shaped, the more stable non-deformable of shape after the atress to there is certain cushioning effect after the suitable inclination atress, can guarantee the life reinforcing of whole device. If the first carrier bar 1 and the second carrier bar 2 are completely parallel to each other, the first carrier bar and the second carrier bar are not stable enough, and therefore the first carrier bar and the second carrier bar are prone to deformation after being stressed.

The reinforcing rod 4 is connected with the middle position of the first bearing rod 1, and the reinforcing rod 4 is connected with one end of the second bearing rod 2 close to the hook 6. Because 6 one end of second load pole 2 couple is the stress point, 5 departments of operation hanging hole are the point of application of force, be close to the stress point with stiffener 4, can ensure that the ability of the bearing capacity of second load pole 2 is stronger, at the in-process that pulls open, the whole pole portion atress of first load pole 1, under the tensioning force effect, the knife brake 10 of 7 lug connection on the base of first load pole 1, so the base 7 end of first load pole 1 generally can not destroyed, but first load pole 1 also has great atress near one side of connecting plate, so set up stiffener 4 at the middle part of first load pole 1, ensure the stability of whole pole piece. As the whole device is asymmetric and the stress is asymmetric, the reinforcing rod 4 is arranged between the two stem rods, the arranged position is asymmetric, and the reinforcing rod 4 is installed according to the stress condition.

The operation hanging hole 5 is close to one end of the second bearing rod 2. In order to save labor, the operation hanging hole 5 is arranged at one end close to the second bearing rod 2, the operation hanging hole 5 is used as a force application point, and the operation hanging hole is close to a force application point in the height direction, so that the device can save more labor.

The base 7 may be a claw buckle, or may be a clip or other structure that can be matched with the knife switch 10, as long as the base can be fixedly connected with the knife switch 10 and the connection relationship is ensured.

The first bearing rod 1 and the second bearing rod 2 are both cylindrical. The first bearing rod 1 and the second bearing rod 2 are arranged in a cylindrical shape, so that the adaptability is good, and various disconnecting links 10 can be used. If square or polygonal columns are used, the knife switch 10 may not be matched, and the body with edges may be worn seriously, and at the same time, the knife switch 10 may be worn, which may cause damage to the knife switch 10.

Two reinforcing plates 3 are welded on the two opposite sides of the first bearing rod 1 and the second bearing rod 2, and a gap is arranged between the two reinforcing plates 3. The welding of the two reinforcing plates 3 is firstly a matter of strength, and in addition to the same strength, the material used for the gap between the two plates will be much lower than for the whole solid plate.

One section and more than one section of bend are formed at the position of the hook 6, and the bent end part of the last section of the hook 6 is close to the second bearing rod 2. The hook 6 is provided with one or more bends, the bend forms a hook 6 with a small opening, but the bend has a bent edge angle or is provided with a ring with a notch, so that the hook structure is ensured, the hook is used for hooking the hanging buckle 9 on the disconnecting link 10, and the connection safety and stability are ensured.
