Abstract

The utility model relates to an electroscope for detecting the presence of electric charge in a high-voltage electrical device, particularly a high-voltage electroscope. The high-voltage electroscope is composed of a detecting pen head (1), a plurality of section rods (2) and threaded locks (3). The detecting pen head (1) is connected with the section rods (2) via the threaded locks (3). When an electrical operator detects the high voltage at a high altitude, the detecting pen head is connected on one section rod via the threaded lock positioned at the inner lower end of the pen head and the threaded lock positioned at the outside upper end of the section rod and then the section rods are connected in the same way according to the altitude of the electrical device, so that the electrical operator can measure the voltage of the high-voltage electrical device at the high altitude by merely standing on the ground. Therefore, the electroscope facilitates the voltage measurement of the high-voltage electrical device at the high altitude, ensures the personal safety of the electrical operator, and is suitable for the use in various high-voltage electrical devices.

Description

The high voltage testing pen

Technical field

The utility model relates to measures electroscope, especially the high voltage testing pen whether high voltage has electricity in the electrical equipment.

Background technology

At present, in electrical equipment, measure high-tension electroscope and need mostly be concertina type for personal safety and high voltage installation, but because the limited length of the electroscope of concertina type, therefore, when measuring the eminence high voltage electric apparatus, the electrician sometimes needs to step on aloft and to measure, and survey crew is stepped on and is easy to generate danger pinnacled the time like this, has only when electroscope can increase length as required just can address this problem.

Summary of the invention

Goal of the invention of the present utility model is: designed a kind of high voltage testing pen that can increase length as required, this electroscope adopts the method for more piece bar screwed connection to form longer electroscope, like this when measuring the eminence high-tension electricity, to connect into certain-length just passable as long as each pole tightened by screw thread; To achieve these goals, the utility model be achieved in that the high voltage testing pen by: electrical verification nib, pole and screw thread are formed; It is characterized in that: the electrical verification nib on pole, has all designed screw thread at the two ends of pole by screwed connection; Wherein: the screw thread design of pole upper end is in the outside of pole, and the screw thread design of electrical verification nib and pole lower end is in the inside of pole.When the electrician measure eminence high-tension the time with screw thread and the pole upper end outside screwed connection of electrical verification nib by inside, lower end on pole, and then in a like fashion the height of several poles according to electrical equipment linked together again, as long as standing in ground, survey crew just can measure the voltage of eminence electrical equipment; So not only can measure the high voltage of eminence electrical equipment easily, can also guarantee electrician's safety, therefore be applicable to the use of various high voltage electric equipments.

Description of drawings

Accompanying drawing is the rough schematic of high voltage testing pen.

Embodiment

Below with reference to the accompanying drawings (as shown in the figure) the utility model is described further: the high voltage testing pen by: electrical verification nib 1, pole 2 and screw thread 3 are formed; At first: outside in pole upper end, electrical verification is written and screw thread is all designed in the inside of pole lower end; Make the outside screw thread in pole upper end can twist on the screw thread of the inside that is connected on electrical verification nib and pole lower end.

Claims

1, a kind of high voltage testing pen by: electrical verification nib (1), pole (2) and screw thread (3) are formed; It is characterized in that: electrical verification nib (1) is connected on the pole (2) by screw thread (3), has all designed screw thread (3) at the two ends of pole (2); Wherein: screw thread (3) design of pole (2) upper end is in the outside of pole (2), and the design of the screw thread of electrical verification nib (1) and pole (2) lower end is in the inside of pole (2).
