Abstract
The utility model relates to a point-polarity pole, in particular relates to an insulating telescopic point-polarity pole used for inspecting the polarity of a current transformer. The insulating telescopic point-polarity pole can implement point-polarity work just on the ground so as to fulfill the aim of reducing the danger coefficient and the labor intensity of the construction. The main technique scheme of the utility model is that: the insulating telescopic point-polarity pole comprises a main pole and a secondary pole, wherein a handle of the main pole is internally hollow; a battery is arranged in the handle; the main pole is provided with a test button which is connected with idler wheel legs of an idler wheel by wires; a hook arranged on the top of the main pole is connected with the idler wheel by a wire; a wire socket is arranged at the bottom of the main pole; the wire socket is connected with the secondary pole which is also provided with the idler wheel; and the wire on the idler wheel connects the hook on the top of the secondary pole with the bottom of the secondary pole. The battery is in short circuit when the test button is pressed down, and the loop is disconnected when the test button is released.
Description
Technical field
The utility model relates to a kind of some polarity pole, and concrete is a kind of flexible point of an insulation polarity pole that is used to check current transformer polarity.
Background technology
Current return is very important loop in the secondary circuit, and in order to guarantee the correctness of electric substation's current return, a job wherein must doing is carried out polarity check to current transformer exactly.Specific practice is on electric primary equipment current transformer; Inductance characteristic according to current mutual inductor coil; Utilize the dry cell transient short-circuit current to be induced to the secondary side of current transformer; Whether identical through reometer supervision secondary side current direction with the primary side current direction, judge that whether the secondary wiring of current mutual inductor mode satisfies the electrical construction requirement, is commonly called as a polarity.The point pole sex work is the important ring in the electrical construction process, and the mistake of polarity will cause the action of electric protection device mistake in operational process and cut off supply load, and society is caused tremendous influence.
In work in the past; Because the Partial Jobs place is installed on the electric power framework; Carry out operation so the workmen often need ascend a height, work difficulty increases greatly, and when operation is carried out operation in the electric substation; Non-charged position tends to the existence of induced charge, and causes workmen's probability that gets an electric shock to increase greatly.
And when traditional work, often adopt interim welding two joint dry cells to make a polarity power supply, not only make trouble, and be difficult for preserving.
Summary of the invention
The utility model is big to workmen's work difficulty in the prior art, construction is dangerous; And the some polarity test tool making of prior art bothers, is difficult for shortcomings such as preservation; Invented the flexible point of a kind of insulation polarity pole; It can just can carry out the point pole sex work on ground, to reach the purpose that reduces construction danger coefficient and labour intensity.
The above-mentioned technical matters of the utility model is able to implement through following technical scheme: the flexible point of a kind of insulation polarity pole, and the flexible point of described insulation polarity pole comprises main pole and secondary pole, the grip inner hollow of main pole; The set inside battery; Main pole is provided with test button, and test button is connected with the roller pin of roller through lead, have one be arranged on main pole top hook pass through lead and be connected with roller; The bottom of main pole is provided with wire jack; Wire jack auxiliary connection pole also is provided with roller on the secondary pole, the lead on the roller is communicated with the hook and the secondary pole bottom at secondary pole top.Battery is by short circuit when pressing test button, unclamp test button after the loop break off.
As preferably, the surface of described main pole and secondary pole is an insulation course, to improve security.
As preferably, described main pole and secondary pole are made up of several telescopic joints, so just can stretch according to actual operating position, to satisfy the demand of different working-yards.
As preferably, described roller is the metal roller.
As preferably, described test button is the light emitting diode button.
The utility model beneficial effect and advantage compared with prior art is following:
1, the utility model is simple in structure, lightly convenient, can stretch into the interior small space of low-tension switch cabinet and carry out the point pole sex work, avoids the workmen to pierce operation, reduces labour intensity, avoids clothing to pollute;
2, avoid ascend operation, can reduce the danger coefficient of high falling and electric shock greatly;
3, entire body adopts insulating material, can be high pressure resistant, and promptly mistiming is bumped charging equipment and also can not damaged the workmen;
4, adopt the button of inner band light emitting diode, diode extinguishes when the loop is obstructed, reminds the workmen that the loop is checked;
5, bright-colored, visual impression is strong, can play certain reminding effect;
6, applied widely, in light weight, can be easy to carry and preserve.

Embodiment
Through embodiment,, do further bright specifically below to the technical scheme of the utility model in conjunction with accompanying drawing:
Embodiment 1: like Fig. 1, shown in Figure 2, and the flexible point of a kind of insulation polarity pole, the flexible point of described insulation polarity pole comprises main pole 1 and secondary pole 2, the surface of main pole and secondary pole is an insulation course, and is made up of several telescopic joints 10.Handle 3 place's inner hollow of main pole, set inside battery 9, main pole is provided with test button 4; Test button is connected with the roller pin of roller 6 through lead 5; Have one be arranged on main pole top hook 7 be connected with roller through lead, the bottom of main pole is provided with wire jack 8, wire jack auxiliary connection pole; Also be provided with roller on the secondary pole, the lead on the roller is communicated with the hook and the secondary pole bottom at secondary pole top.Described roller is the metal roller.Described test button is the light emitting diode button.
Use the utility model,, can carry out the point pole sex work on ground, it is more quick not only to work, and easy to use, has improved workmen's work efficiency and security greatly.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
