Description

A kind of charged shows signal sampler
Technical field
The utility model relates to a kind of signal sampling device, relates in particular to the charged shows signal sampler of a kind of high-pressure conductor.
Background technology
For clear and definite circuit whether charged, all be provided with measuring device with electricity in many high-tension circuits, charged shows signal sampling theorem is equivalent to: high-voltage charged body and sample of signal metallic object have constituted the two poles of the earth of a capacitor, outside the sample of signal metallic object, connect a signal lamp, when on the high-voltage charged body High Level AC Voltage being arranged, the sample of signal metallic object just constantly discharges and recharges, and has electric current to pass through in the signal lamp thereby make, signal lamp is just light, thereby on the clear and definite high-pressure electrified conductor High Level AC Voltage is arranged.
Present charged sample of signal facility does not have the device of ad hoc structure, it generally adopts and twines stainless steel wire as electric capacity one utmost point outside high-tension cable, uses fixedly stainless steel wire of adhesive plaster and heat-shrink tube again, and the outer signal lamp, have high-tension current to pass through in cable like this, signal lamp just lights.Stainless steel wire in such shows signal facility is adopted to such an extent that the voltage signal insufficient strength is stable, and fragile in the assembling process of electrical equipment, and it is loaded down with trivial details that it reinstalls process.
The utility model content
The utility model provides a kind of charged shows signal sampler in order to overcome the defective of the facility that shows signal is gathered in the at present existing high-tension circuit, and it can gather stable voltage signal, and installation is more convenient.
The charged shows signal sampler of the utility model is achieved through the following technical solutions purpose:
Adopt the advantage of the charged shows signal sampler of the utility model to be:
A kind of charged shows signal sampler wherein, comprises inductance loop and the conduction of current bar that is connected on the described inductance loop; Described conduction of current bar is provided with the current output terminal mouth; Described inductance loop is wrapped in the insulating element.
Above-mentioned charged shows signal sampler, wherein, described current output terminal mouth is connected to signal display apparatus.
Above-mentioned charged shows signal sampler, wherein, described insulating element is epoxy resins insulation; On described epoxy resins insulation, be positioned at described inductance loop center section and be provided with the placement through hole that is used to place detected energized conductor.
Above-mentioned charged shows signal sampler, wherein, described conduction of current bar one end and described inductance loop are fixedly linked, and are fixedly installed in the insulator; The other end is provided with electric current output screw, and exposes outside described insulator.
Above-mentioned charged shows signal sampler wherein, is equipped with signal lamp in the described electric current output screw.
Above-mentioned charged shows signal sampler, wherein, described inductance loop becomes by copper with the conduction of current bar.
Adopt the beneficial effect of the charged shows signal sampler of the utility model to be:
1. the charged shows signal sampler of the utility model voltage signal intensity of adopting is more stable, and during use, its signal that provides is more reliable.
2. the charged shows signal sampler of the utility model is simple in structure, and it is convenient to install, and not fragile, and it is more stable to work, and practicality is stronger.
Description of drawings
Fig. 1 is the structural representation of a kind of charged shows signal sampler of the utility model;
Fig. 2 is the vertical view of a kind of charged shows signal sampler of the utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of charged shows signal sampler is used to detect energized conductor 1 and whether has alternating current, comprises inductance loop 2 and conduction of current bar 3 as current sensing means, and described inductance loop 2 and conduction of current bar 3 all are made of copper.Described inductance loop 2 and conduction of current bar 3 are cast in epoxy resins insulation 5, on described epoxy resins insulation 5, are positioned at described inductance loop 2 central authorities and offer the placement through hole 7 that is used to place described energized conductor 1.Like this, described inductance loop 2 just is placed in outside the described energized conductor 1, and described energized conductor 1 and inductance loop 3 have constituted the two poles of the earth of a capacitor, and when on the high-voltage charged body High Level AC Voltage being arranged, the sample of signal metallic object just constantly discharges and recharges.One end of described conduction of current bar 3 is fixedlyed connected with described inductance loop 2, and its other end is provided with the electric current output screw 4 as signal output port, and described electric current output screw 4 exposes outside described epoxy resins insulation 5, and signal lamp 6 has been installed.When described energized conductor 1 is connected with High Level AC Voltage, then described inductance loop 2 constantly discharges and recharges, and with electric current by described conduction of current bar 3, link signal lamp 6, make it shinny.Whether so just can detect to detect in the described energized conductor 1 has electric current to pass through.
The voltage signal that a kind of charged shows signal sampler of the utility model is gathered is more stable, more reliable, and it is easy for installation, is difficult for being damaged when the assembling of electrical equipment.
Will be appreciated that; the above embodiments are only as exemplifying and propose preferred embodiment of the present utility model; the utility model also not only is confined to this, and the various simple modifications that those skilled in the art can implement also should fall in the protection domain of the present utility model.
