Description

Technical Field

Substations include "step-up" and "step-down" substations of various voltage levels. When the internal equipment of the substation malfunctions, the maintenance personnel need to first detect and determine the fault point. The maintenance personnel first determine the fault by checking the circuit. The staff first need to sort out the circuit, but because there are many circuits, sorting is difficult.

The housing 21 has a storage space inside to accommodate maintenance tools 214. A turntable 213 is rotatably mounted inside the storage space. The turntable 213 has at least one tool position. An electric push rod is fixedly mounted on the tool position. The telescopic end of the electric push rod is fixed to the maintenance tool 214 through a fixing mechanism 24. It can be understood that each tool position is used to fix one maintenance tool 214. When the maintenance tool is needed, the telescopic end of the electric push rod is extended to push the maintenance tool 214 out of the housing 21.

[0033] Example 2

[0034] This invention provides an insulation protection device for the maintenance of equipment in urban power grid substations, such as... Figure 1-4 As shown, the device includes an operating tool 2 for maintaining substation equipment and an operating lever 1 for controlling the movement of the operating tool. The operating lever 1 is made of insulating material to protect maintenance personnel during operation and prevent electric shock accidents. The operating tool 2 includes a housing 21 and a cover 22 mounted on the housing 21. The housing 21 is fixedly connected to the operating lever 1. The housing 21 has a storage space inside to accommodate maintenance tools 214. A turntable 213 is rotatably mounted inside the storage space. The turntable 213 has at least one tool position. An electric push rod is fixedly mounted on the tool position. The telescopic end of the electric push rod is fixed to the maintenance tool 214 through a fixing mechanism 24. It can be understood that each tool position is used to fix one maintenance tool 214. When the maintenance tool is needed, the telescopic end of the electric push rod is extended to push the maintenance tool 214 out of the housing 21. Then, the maintenance personnel operate the maintenance tool 214 through the operating lever 1 to maintain the substation equipment.

[0035] Furthermore, the cover 22 is detachably connected to the housing 21. The cover 22 has an opening 221 for the maintenance tool 214 to extend out of the housing 21. Since the storage space inside the housing 21 stores multiple maintenance tools 214, when a certain type of maintenance tool is needed, the turntable 213 is rotated to rotate the maintenance tool 214 to the opening 221, and then the maintenance tool 214 is pushed out by the electric push rod.

[0036] In this embodiment of the invention, a rotary motor 211 is fixedly installed inside the housing 21, and the output end of the rotary motor 211 is fixedly connected to the rotating shaft of the turntable 213 to drive the turntable 213 to rotate.

[0037] Furthermore, a frame 212 is also provided inside the housing 21, and the rotating shaft of the turntable 213 is rotatably connected to the frame 212.

[0040] Please see Figure 2-3 The difference between this embodiment and Embodiment 1 is that:

[0041] Each tool position on the turntable 213 is equipped with a button 217 on its side. The button 217 is used to control the power supply of the electric actuator. When the button 217 is pressed down, the electric actuator power supply is activated to supply power to the electric actuator. When the button 217 is depressurized, the electric actuator power supply is turned off, and the corresponding electric actuator is de-energized. A top block 216 is fixedly installed on the inner wall of the housing 21. The top block 216 is located near the opening 221. During the rotation of the turntable 213, when the button 217 on the side of the tool position is pressed against the top block 216, the button 217 is pressed down, and the corresponding electric actuator is energized. In addition, the operating lever 1 is also equipped with an operating button to control the operation of the electric actuators in each tool position. This operating button is used to control the extension and retraction of the energized electric actuators to extend or retract the maintenance tool 214 into the housing 21.

It can be understood that each tool position is used to fix one maintenance tool 214. When the maintenance tool is needed, the telescopic end of the electric push rod is extended to push the maintenance tool 214 out of the housing 21. Then, the maintenance personnel operate the maintenance tool 214 through the operating lever 1 to maintain the substation equipment.

[0044] Furthermore, the cover 22 is detachably connected to the housing 21. The cover 22 has an opening 221 for the maintenance tool 214 to extend out of the housing 21. Since the storage space inside the housing 21 stores multiple maintenance tools 214, when a certain type of maintenance tool is needed, the turntable 213 is rotated to rotate the maintenance tool 214 to the opening 221, and then the maintenance tool 214 is pushed out by the electric push rod.

[0047] In addition, the operating lever 1 is provided with a power supply for the rotary motor 211, and the power supply is electrically connected to the rotary motor 211 through the wire 23.

[0048] Please see Figure 5 In this embodiment of the invention, the cover 22 is also provided with a camera 222 for capturing images of the maintenance area, and a first light 223 and a second light 224 for illuminating the camera 222.

[0049] Please see Figure 2-3 The difference between this embodiment and Embodiment 1 is that:

[0050] Each tool position on the turntable 213 is equipped with a button 217 on its side. The button 217 is used to control the power supply of the electric actuator. When the button 217 is pressed down, the electric actuator power supply is activated to supply power to the electric actuator.
