Most 10kV overhead lines are erected in the field, the operation environment is severe, and the failure occurrence rate caused by external force damage such as thunder and lightning, strong wind, rainstorm and the like is high. When the overhead line has a single-phase earth fault, the line inspection is difficult due to the fact that fault section positioning cannot be achieved, safety of people and livestock is endangered, and reliability of regional power supply is greatly reduced.
To solve this problem, the fault indicator 100 is generally installed on an overhead line, and in case of a fault in the line, the fault indicator 100 indicates the type of the fault by flashing different indicator lights. As shown in fig. 1, the fault indicator 100 includes an upper case 101 and a lower case 102 rotatably connected to each other, the upper case 101 can be fastened to the lower case 102, and a torsion spring is disposed between the upper case 101 and the lower case 102 and can drive the upper case 101 to rotate in a direction fastened to the lower case 102. When the upper case 101 and the lower case 102 are engaged, a via hole 103 through which a line passes exists between the upper case 101 and the lower case 102. However, the diameters of different lines are different, and in order to improve the applicability of the fault indicator 100, the lower shell 102 is rotatably connected with two clamp springs 104, the rotation directions of the two clamp springs 104 are opposite, and the two clamp springs 104 both have a tendency to rotate towards the other clamp spring 104, so as to clamp the lines between the two clamp springs 104 and the lower shell 102.
Because the fault indicators 100 are manually installed, an installer must step on a ladder to access the wiring, open the upper housing 101 of the fault indicator 100, place the wiring between the upper housing 101 and the lower housing 102, and then snap-fit the upper housing 101 and the lower housing 102. The installation process needs the installer both hands to operate, falls from the ladder easily and takes place danger, and the installation effectiveness is lower moreover.
Example one
In order to solve the above problem, the present embodiment provides an installation tool for a fault indicator 100, as shown in fig. 2 to fig. 4, the installation tool includes a support 1 and a pushing assembly 2, the support 1 is provided with a first buckle 11, the first buckle 11 is configured to be clamped to an upper shell 101 opened by the fault indicator 100, the pushing assembly 2 includes a base 21 and an elastic member 22, the base 21 is slidably connected to the support 1, and two ends of the elastic member 22 respectively abut against the base 21 and the support 1.
The installation tool can clamp the opened upper shell 101 of the fault indicator 100 by using the first buckle 11, and clamp the fault indicator 100 between the first buckle 11 and the base 21 to keep stable. An installer can hold the installation tool by hand to approach the line, and then continue to push the installation tool to make the line pass through the fault indicator 100 and drive the base 21 to compress the elastic member 22 after the line abuts against the lower shell 102 of the fault indicator 100, at this time, the distance between the base 21 and the first buckle 11 is increased, so that the upper shell 101 of the fault indicator 100 is separated from the first buckle 11 and buckled on the lower shell 102, and the installation of the fault indicator 100 is completed.
This mounting tool can realize the one-hand installation, and the security is high, and easy operation has improved the installation effectiveness.
Specifically, the elastic member 22 is a spring.
As shown in fig. 2 to 4, the installation tool further includes a second buckle 3, the second buckle 3 is rotatably disposed on the bracket 1, the second buckle 3 is configured to be clamped on an edge of the lower shell 102 of the fault indicator 100, and a bayonet direction of the second buckle 3 faces downward. Because the installation tool places the fault indicator 100 on the base 21 before installing the fault indicator 100, and the base 21 is supported by the elastic member 22, which is not stable enough, the second buckle 3 can press the fault indicator 100 against the base 21 by clamping the edge of the lower shell 102 of the fault indicator 100, at this time, the base 21 compresses the elastic member 22, which is equivalent to the elastic member 22 elastically pressing the base 21 and the fault indicator 100 against the second buckle 3, so that the fault indicator 100 is in a stable state. When the line abuts against the lower shell 102, the fault indicator 100 presses the elastic member 22 to move downward, so that the second buckle 3 is separated from the edge of the lower shell 102, thereby ensuring that the fault indicator 100 can be separated from the installation tool. To further improve the stability of the fault indicator 100 inside the bracket 1, the mounting tool comprises a plurality of second catches 3.
As shown in fig. 2 to 4, the mounting tool further includes a third buckle 4, the third buckle 4 is rotatably disposed on the bracket 1, and the third buckle 4 is configured to clamp the clamp spring 104 opened by the fault indicator 100. The third latch 4 can open the latch spring 104 of the malfunction indicator 100, which facilitates an operator to place a circuit between the latch spring 104 and the lower case 102. When the circuit abuts against the lower shell 102, the fault indicator 100 compresses the elastic member 22 downward, and at this time, the third latch 4 is disengaged from the snap spring 104, so that the snap spring 104 can abut against the circuit against the lower shell 102. It will be appreciated that the mounting tool is provided with at least two third catches 4, and each third catch 4 catches one catch spring 104. In order to ensure the stability of the clamp springs 104 when clamped by the third clamp buckles 4, in the embodiment, the installation tool includes four third clamp buckles 4, and each clamp spring 104 is clamped by two third clamp buckles 4.
However, since the snap spring 104 is rotatably connected to the lower case 102, that is, when the fault indicator 100 moves downward, the snap spring 104 may rotate relative to the lower case 102 to cause the third snap 4 not to be disengaged from the snap spring 104, so that the installation tool may not be finally disengaged from the fault indicator 100, and the third snap 4 is disengaged from the snap spring 104 when an operator manually operates, which reduces efficiency and increases danger.
As shown in fig. 3 and 4, for solving this problem, mounting tool still includes unlocking piece 5, and unlocking piece 5 rotates and sets up in support 1, and unlocking piece 5 is connected with the transmission of third buckle 4, and base 21 can butt unlocking piece 5 when moving towards the direction of compression elastic component 22 to drive third buckle 4 and rotate in order to unblock jump ring 104. The unlocking member 5 ensures that the third latch 4 is surely disengaged from the latch spring 104 during the downward movement of the malfunction indicator 100 to compress the elastic member 22, so that the latch spring 104 can press the circuit against the lower case 102 and the installation tool can be disengaged from the malfunction indicator 100.
As shown in fig. 3 and 4, the installation tool further includes a transmission member 6, and both ends of the transmission member 6 are respectively pivoted to the unlocking member 5 and the third buckle 4. When the unlocking piece 5 rotates under the driving of the base 21, the unlocking piece 5 drives the transmission piece 6 to move, so that the third buckle 4 rotates towards the direction far away from the clamp spring 104, and the third buckle 4 is ensured to be unlocked from the clamp spring 104.
Specifically, in the present embodiment, when the base 21 abuts against the unlocking member 5 to make one end of the unlocking member 5 rotate downward, the other end of the unlocking member 5 drives the transmission member 6 to move upward, and the transmission member 6 pushes the third buckle 4 to rotate upward, so that the third buckle 4 is separated from the snap spring 104.
As shown in fig. 3 and 4, the base 21 is formed with a receiving groove 211, and the receiving groove 211 is formed to be adjacent to the fault indicator 100. The bottom of fault indicator 100 is the hemisphere casing that transparent plastic or glass made, and the holding tank 211 of base 21 also is the hemisphere recess, and the internal diameter of holding tank 211 equals with fault indicator 100's hemisphere casing's external diameter, and fault indicator 100's hemisphere casing can be laminated with the inner wall of holding tank 211 to guarantee fault indicator 100's stability.
Preferably, the bracket 1 includes a sleeve 12 and at least two supporting members 13, the at least two supporting members 13 are disposed at intervals along the outer circumference of the sleeve 12, the base 21 is slidably disposed in the sleeve 12, and the first buckle 11 is rotatably disposed on the top of one of the supporting members 13. The sleeve 12 can play a guiding and protecting role for the fault indicator 100 and the base 21, and the supporting members 13 are used for arranging the first fastener 11, the second fastener 3 and the third fastener 4, specifically, each supporting member 13 is provided with two second fasteners 3 and three third fasteners 4.
Further, a plurality of linear bearings are provided at intervals in the circumferential direction on the inner wall of the sleeve 12, and when the failure indicator 100 enters the sleeve 12, the outer wall of the failure indicator 100 is in rolling contact with the plurality of linear bearings. The linear bearing can serve both to guide the fault indicator 100 and to prevent the outer tube of the fault indicator 100 from being damaged due to friction between the fault indicator 100 and the inner wall of the sleeve 12.
Example two
In the embodiment, the structure of the bracket 1 is improved on the basis of the first embodiment.
In the present embodiment, the bottom of the bracket 1 is provided with a mounting portion 14, and the mounting portion 14 is used for mounting a support rod. It can be appreciated that the lines are generally erected at a higher position, and when an operator supports the installation tool by using the support rods, the operator can stand on the ground to install the fault indicator 100, so that the process of climbing a ladder is omitted, the efficiency can be improved, and the risk can be reduced.
