Abstract
The utility model discloses an insulated operating rod which comprises a metal operating head, a power testing display box, and a main tube of the operating rod. The metal operating head is installed at the front end of the main tube of the operating rod. The power testing display box is fixedly disposed on the tube wall of the main tube of the operating rod. A sound and light alarm circuit is disposed inside the power testing display box. The sound and light alarm circuit is connected to the metal operating head. According to the utility model, resource waste is eliminated and production materials are saved. Moreover, one insulating rod is saved while two different electric power tools, which are respectively provided with an insulating rod, need to be equipped. Time is also saved. In a conventional operation process a knife switch is operated at first by a pull rod and then an electroscope is adopted to test power, and the whole process at least needs 1 minute and 40 seconds, however, more than 40 seconds can be saved by adoption of the present operation process. In particular, the beneficial effects are particularly prominent in a rapid emergency repair process.
Description
Technical field
The utility model relates to a kind of electric power apparatus, particularly relates to a kind of insulating bar.
Background technology
Insulating bar is one of the most frequently used security tool of the rural power staff of basic unit, is mainly used in the insulating tool that the short time operates charging equipment, as is switched on or switched off high voltage isolator, falls fuse device etc.Existing a kind of insulating bar, comprise insulating bar and the working head that is installed in insulating bar one end, described insulating bar is a plurality of insulating bar sections, in a plurality of insulating bar sections wherein one section insulating bar sections one end be equipped with pullover, the other end is equipped with nipple or pullover, all the other insulating bar sections one ends are equipped with pullover, the other end is equipped with nipple, the pullover trepanning that is provided with, nipple is provided with boss, and the external diameter of boss matches with the trepanning internal diameter, the pullover draw-in groove that is provided with, boss is provided with projection, and the size of projection matches with draw-in groove.
The electroscope of existing power apparatus field, top are a metallic plate (perhaps also useful metal ball), and it is connected with Metallic rod, and Metallic rod is passed rubber stopper, and the lower end hangs two goldleaf as thin as a wafer, is encapsulated in the vial.During check, object is contacted with metallic plate, if object is charged, pass on two goldleaf with regard to some electric charge, goldleaf has been owing to be with like charges, repel each other and open, with electric charge more many, open angle is more big; If object is not charged, then goldleaf is motionless.When known object is charged, if will identify its charged kind, as long as earlier this electrified body is contacted with Metal Ball, goldleaf is opened.Then, contact galvanoscopic Metal Ball with the known object with abundant positive electricity again, if the open angle of goldleaf is bigger, the electric charge of then representing this electrified body is positive; Otherwise if the open angle of goldleaf reduces, or first closure then opens, and represents that then the electric charge of electrified body is born.The above fact means that when electrified body increased like charges again, the value of electric charge increased; When electrified body increased the xenogenesis electric charge again, the value of electric charge reduced.Therefore, people usually positive and negative electric charge is expressed as respectively on the occasion of and negative value.For example.The object that will have equivalent xenogenesis electric charge contacts, and they are with the algebraical sum of positive and negative electric charge is zero, shows as external electrical effect and cancels out each other, just like not charged the same.At this moment, they are electric neutrality.This phenomenon is called discharge or charge neutrality.But atomic nucleus with positive charge and electron outside nucleus with negative electrical charge between interactional electrical power, with the difference of material power is arranged.If several neutral atom or molecules are arranged, because extenal causes, lose one or several electronics, then in these atoms or the molecule all protons with positive charge more than whole negative electrical charges of electron institutes band, so they have obtained positive charge and have become cation; Otherwise if having several neutral atoms or molecule to obtain one or several electronics from the external world, then these atoms or intramolecular negative electrical charge are more than positive charge, so they have obtained negative electrical charge and have become anion.Above-mentioned these phenomenons are called ionization.Under these two kinds of ionization situations, concerning whole object, all present electriferous state.
In the distribution professional domain, in the time of each operation 10KV isolating switch, disconnecting link, fuse, all insulating bar and electroscope be to carry, insulating bar or electroscope carried always the discovery of still once or several times reaching the spot has been forgotten, and no matter how far also will go back to get.Need be used alternatingly insulating bar and electroscope back and forth during operation, operation is not very convenient.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of insulating bar.
The insulating bar that the utility model provides, comprise metallic operation head, electrical verification display box and the action bars person in charge, described metallic operation head is installed on the front end that described action bars is responsible for, described electrical verification display box is fixedly set on the described operation person in charge's the tube wall, be provided with sound light alarming circuit in the described electrical verification display box, described sound light alarming circuit is electrically connected to described metallic operation head.
According to the utility model, both can operate 10KV isolating switch, disconnecting link, fuse etc., can carry out electrical verification work again at any time, protection staff's personal safety.After having operated disconnecting link, can just can install earth connection immediately after item by item the electrical verification respectively.And the waste of having saved resource, save the making material, originally needed to be equipped with two kinds of different electric power tools, all tape insulation rod, saved an insulating rod now, saved the purchase fund, also saved the operating time, originally wanted to operate disconnecting link with pull bar earlier, changing the electroscope electrical verification into, minimum needs of this process 1 minute and 40 seconds, and operation now can be saved the time more than 40 seconds, it is particularly outstanding especially to be embodied in the quick repairing process beneficial effect.In addition, also reduced the loading capacity of electric car, reduced emission factor, for environmental protection contributes.
