Description
Technical field the utility model belongs to a kind of measurable new type current transformer in high voltage of testing.
The existing current transformer of background technology detects, and measures the employed iron core by a sealing of electric current and is formed with the primary coil and the secondary coil that are wrapped on the iron core.Secondary coil is connected with ammeter during measurement, and primary coil is series in the circuit-under-test, and there are many problems in such current transformer.At first, in essence, it is a kind of special transformer, the electricity consumption circulation becomes the current transformer of voltage power supply, the electric current of secondary coil is big when measuring electric current, voltage is high, is a kind of breakneck surveying instrument, can not open a way during operation, in case secondary line has been opened the road, will cause equipment and personal safety accident; The secondth, the scope that this mutual inductor is measured is little, will select the proportioning current transformer and the reometer that are fit to when measuring electric current, if select improper may cause measure inaccurate or electric current excessive, burn out current transformer and ammeter, cause unnecessary accident.The 3rd current transformer is when measuring big electric current, and volume also will increase thereupon, not only expends the copper material steel, results in hand cramps also for simultaneously the dismounting when installing and keeping in repair.Current transformer will be connected in the main traverse line when measuring electric current, measures the secondary lead that connects reometer and also requires slightlyer, has brought a lot of problems so just for remote remote measuring and controlling.
Summary of the invention the objective of the invention is to propose little, the no secondary coil of a kind of volume, not only can measure low-tension current, also can measure high-tension current, and the measurable testable novel high-pressure ac current signal inductor that energy and non-conducting material combine is to solve the deficiencies in the prior art.
This measurable testable novel high-pressure ac current signal inductor that the utility model proposes, it is cored and be wrapped in coil on the iron core, the induction mouth that disconnection is arranged on the iron core, it is characterized in that iron core and coil all are contained in the non-conducting material, respond under the tight-lipped surface of being located at the non-conducting material that contacts with high-voltage conducting wires.Coil has connection terminal.
Non-conducting material is high-tension electricity insulating porcelain bushing or insulator.
Iron core and coil stationary are responded to tight-lipped by the box shell, outside the outlet box of coil two ends in an insulation booth.
Iron-core coil box panel is in the insulated porcelain sleeve pipe end, and the box shell of being close to induction mouthful contacts with the mutual inductor end cap or microgap arranged.
The inductor end cap is a metalwork, and the fixedly screw hole of high-voltage conducting wires is arranged.
Using method of the present utility model is: the high-voltage conducting wires that desire is measured or desire is tested is fixed on the end cap of responding to mouth or the box surface, also can allow high-voltage conducting wires near inductor, the lead-in wire two ends of coil are connected with reometer or watt-hour meter, perhaps be connected and just can form safe and reliable measuring mechanism with existing digital circuit, connect the digital current controller, its control accuracy can reach 1 ampere electric current, realizes the purpose of remote digital remote measuring and controlling and metering.
The utility model volume is little, when inductor is made the box shape, its volume has only square several centimetres, be convenient to install and save material, reduce production costs, do not have secondary coil, can not produce the high voltage induction electric current, the instrument that can not burn out inductor and be attached thereto, yet not entail dangers to personal safety; Not only can measure low-tension current, also can measure high-tension current, and can and non-conducting material combine and measure at a distance, test and monitor.
Appended drawings 1 is front view of the present utility model (broken section).
Accompanying drawing 2 is inductor end cap front views.
Accompanying drawing 3 is base front views of insulating porcelain bushing.
In the accompanying drawing, each parts and corresponding label are as follows:
1-inductor end cap; 2-inductor; 3-lead-in wire; 4-porcelain bushing shell; 5-lead-in wire road; 6-connection terminal; 7-base; 8-base screw hole; 9-base mounting screw hole; 10-high-voltage conducting wires fixed orifice.
Embodiment as Figure 1-3, inductor 2 is made up of iron core, coil, shell and connection terminal, its structure and application number are 95228296.8 patent structure basically identical, a breach is arranged on the iron core, mouthful close fixedly place of high-voltage conducting wires of induction just, the inductor panel is in the end of insulating porcelain bushing 4, and insulating porcelain bushing is a kind of insulator of using on the ultra-high-tension power transmission line, hollow forms lead-in wire road 5, and lead-in wire 3 and connection terminal 6 are drawn from the lead-in wire road and be connected on the supporting circuit.Insulating porcelain bushing is fixing by its base 7, inductor inductor end cap 1 capping.Also have some fixedly fixed orifices 10 etc. of high-voltage conducting wires on the end cap.
The volume of inductor is very little, and physical dimension has only 45 * 40 * 35MM, is convenient to installation separately or panel on the High-Voltage Insulation porcelain bushing shell.Through on probation, this mutual inductor and digital current controller connect to form the current/voltage watch-dog various low pressure, high pressure and UHV (ultra-high voltage) alternating current are measured at a distance and test, and effect is welcome by the trier very as mentioned above.
