Multifunctional switching operation rod

Abstract

The invention relates to an electrical operation and maintenance operation tool, in particular to a multifunctional switching operation rod. The multifunctional switching operation rod is formed by sequentially abutting a head rod, at least one connection rod and a tail rod which are all made of insulation materials, an operation hook and a lighting lamp are arranged on the head rod, a control button and a power supply device are arranged at the lighting lamp in a matching way, a deep hole is formed in the head rod and is arranged along an axial direction of the head rod, the cross section ofthe deep hole is of a polygonal structure, an insertion rod is arranged in the deep hole in a matching way, a cover is arranged at a top end of the insertion rod and is used for protecting a knife switch of an outdoor high-voltage switch, the lighting lamp comprises an LED lamp and an annular lamp strip, the LED lamp is used for achieving cover operation, the annular lamp strip is used for achieving switching operation, an insulator is arranged on the connection rod abutted with the head rod, the insulator is provided with a plurality of layers of annular insulation skirt edge, and the annularinsulation skirt edges are arranged downwards. The multifunctional switching operation rod is simple in structure and ingenious in design and is safe and reliable to operate, the switching operationis suitably performed at night and in a humid environment, corresponding maintenance operation is performed, and the personal safety of an operator is ensured.

Description

technical field [0001] The invention relates to an electrical operation and maintenance operating tool, in particular to a multifunctional switching operating lever. Background technique [0002] At present, outdoor high-voltage switching devices (vacuum circuit breakers, vacuum load switches and isolating switches) are generally installed on high-voltage utility poles, and the installation height is mostly above 6.5 meters. These high-voltage switching devices are equipped with operating handles, and the handle ends of the operating handles are provided with hook rings for operation. In the field, it is usually manually climbed to the electric pole, holds the insulating operating rod, and hooks the operating hook on the top of the insulating operating rod to the articulated ring, and realizes the outdoor high-voltage switchgear by rotating the operating handle. Switching operation. [0003] However, the following problems were found during actual operation: (1) There are ...

Problems solved by technology

[0003] However, the following problems were found during actual operation: (1) There are often low-voltage transmission lines or communication lines on the lower side of the outdoor high-voltage switch devices, so operators cannot approach these high-voltage switch devices, and can only be located 2 to 3 meters away. When operating, the operating line of sight is limited, and the mounting ring is small, which makes the operation difficult, especially at night, where the line of sight is not clear, which increases the difficulty of operation and seriously affects the operating efficiency; (2) in the air In an environment with relatively high humidity, especially when switching operations are performed on cloudy and rainy days, a layer of water film is easily formed on the surface of the insulating operating rod. The exposed low-voltage transmission line on the lower side of the switching device is in contact with each other, which is prone to creepage phenomenon, resulting in electric shock to the human body; (3) When performing line maintenance, it is usually necessary to open the isolating switch. The angle is usually less than 90°, and the knife switch is easy to close automatically under the action of its own weight, which poses a great threat to the operation safety of maintenance personnel
