Abstract

The utility model relates to a multifunctional high-voltage electricity-testing device. The device is characterized in that the device comprises a handheld insulating rod; one end of the handheld insulating rod is detachably connected with one end of a T-shaped brake pull rod (2); and the other end of the T-shaped brake pull rod (2) is detachably connected with an electroscope (1). According to the multifunctional high-voltage electricity-testing device provided by the utility model, the mechanical strength meets the requirement of general occasions; defects that the swinging amplitude is large after lengthening and the electricity-testing portion can not be contacted easily can be overcome; and when the electricity-testing component is disassembled, the device can be used as a brake pull rod, thereby realizing the effect of one object integrated with dual functions. And after the electricity testing, the electricity-testing device can be hung on power failure equipment, thereby ensuring the ground wire installation is secure. Moreover, the electroscope with the voltage of 330 kilovolts or below can be connected according to the on-site working demand; the application range of the device is wide; and there is no need to configure a special-purpose brake pull rod and a special-purpose electricity-testing device additionally, thereby saving the cost.

Description

A multi-functional high-voltage electrical testing device

technical field

The utility model relates to a multifunctional high-voltage electric testing device.

Background technique

The portable retractable high-voltage electroscope is an important tool for power system to safely carry out power transmission and shutdown operations. At present, the widely used electrometers in the power system are all telescopic. According to the different voltage levels, they can be divided into 10kV, 10kV, 35kV, 66kV, 110kV, 220kV, 330kV six types. The structure of the existing portable telescopic high-voltage electroscope is usually composed of a telescoping insulating part and an electroscope part. Under normal circumstances, it must be verified that the power-off equipment has no voltage before the grounding wire is installed during the power-off operation of the high-voltage equipment. At this time, a portable high-voltage electrical inspection device is required. Its advantages are light and easy to carry, but its disadvantages are: single use; the strength decreases after stretching, the swing range is large, and it is not easy to touch the electrical inspection point of the equipment; in the occasions with many voltage levels such as substations, it is necessary to be equipped with various voltage levels. Electric testing device, more investment costs.

Utility model content

The purpose of the utility model is to provide a multi-functional high-voltage electric inspection device, which can be used for high-voltage electric inspection and can also be used as a high-voltage switch lever.

A multifunctional high-voltage electrical testing device, which is special in that it includes a hand-held insulating rod, one end of which is detachably connected to one end of a T-shaped brake rod, and the other end of the T-shaped brake rod is connected to the test rod. Electrical components are detachably connected.

Wherein the hand-held insulating rod is composed of at least two sections of connecting rods, and the two connecting rods are connected by threads.

Among them, threaded connections are used between the hand-held insulating rod and the T-shaped brake rod, and between the T-shaped brake rod and the electrical testing parts.

The mechanical strength of the multifunctional high-voltage electroscope device of the utility model is sufficient for general occasions, without the disadvantages of large swing range after lengthening and difficult contact with the electroscope part. After the electroscope is removed, it can be used as a brake lever, which realizes Use one thing for two purposes. After the power test is completed, the test device can be hung on the power failure equipment, so as to ensure that the installation of the ground wire is safer. In addition, according to the needs of on-site work, you can choose to connect an electroscope with a voltage level of 330 kV and below, which has a wide range of applications, and does not need to be equipped with a special switch rod and electroscope, which saves costs.
