Abstract
The utility model provides a wire & cable short circuit detecting circuit so as to solve such problems existing in the current wire & cable short circuit detection as low efficiency and inability of determining a short circuit point precisely. The wire & cable short circuit detecting circuit comprises a voltage regulator and a voltage-multiplying circuit, wherein the voltage regulator is connected with the voltage-multiplying circuit in series, two steel balls are connected in the voltage-multiplying circuit in series, a gap is reserved between the two steel balls, and the voltage-multiplying circuit is connected with an output end in series. The wire & cable short circuit detecting circuit adopts an AC 220V power supply, and uses the voltage regulator to regulate output voltage. The two steel balls are connected in the voltage-multiplying circuit in series so as to prevent circuit current from being too high and prevent cables or equipment from being burned by the high current. An ammeter and a voltmeter are installed on the equipment, so that conditions of the circuit current and voltage can be observed directly. As for cables with a short-circuit resistance smaller than 2M omega, the wire & cable short circuit detecting circuit can find out the short circuit point accurately, thereby improving the efficiency of wire & cable short circuit detection effectively, enabling countless short-circuit cables to be saved, and acquiring considerable economic benefits.
Description
Technical field
The utility model belongs to the electric wire production field, particularly a kind of electric wire short-circuit detecting circuit.
Background technology
In electric wire is produced
,Because a variety of causes, short circuit between two conductors in the cable of producing sometimes, so in order to ensure the quality of electric wire, must be dispatching from the factory before to the short-circuit detecting of electric wire work.The detection to the short circuit of electric wire at present generally has following several kinds: a kind of is that the position of probably estimating short dot is by rule of thumb cut apart cable, causes very big waste like this, and exists inefficiency, problem that labour intensity is big; Another kind is the resistance that adopts between apparatus measures two short-circuit conductors such as megger, precision type bridge, and through calculating the position of confirming short dot, calculated value has very mistake, also just can't find the cable short circuit point exactly again.
The utility model content
The purpose of the utility model provides a kind of electric wire short-circuit detecting circuit, the inefficiency that exists in the detection with the short circuit that solves existing electric wire, the problem that can not accurately confirm short dot.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of electric wire short-circuit detecting circuit comprises pressure regulator, voltage-multiplying circuit, and said pressure regulator is connected in series said voltage-multiplying circuit, two steel balls of serial connection on the said voltage-multiplying circuit, and gapped between said two steel balls, said voltage-multiplying circuit also is serially connected with output terminal.
Said pressure regulator is in series by adjustable transformer and step-up transformer.
Gap between said two steel balls is 0.1mm-1mm.
The utility model adopts the alternating current 220V power supply, utilizes pressure regulator to regulate output voltage.Two steel balls are serially connected with in the voltage-multiplying circuit, prevent that circuital current is excessive and burn cable or equipment.Electric current, voltage table are installed on the equipment, but Direct observation circuital current and voltage condition.
The utility model can be found out short dot exactly for the cable of short-circuit resistance less than 2M Ω, effectively raises the efficient of electric wire short-circuit detecting, makes countless short circuit cable obtain saving, and has obtained appreciable economic benefit.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model electric wire short-circuit detecting circuit comprises pressure regulator, voltage-multiplying circuit, pressure regulator serial connection voltage-multiplying circuit, and gapped between 1, two steel ball 1 of two steel balls of serial connection on the voltage-multiplying circuit, voltage-multiplying circuit also is serially connected with output terminal 2.
Pressure regulator is in series by adjustable transformer TG and step-up transformer TR.
Gap between two steel balls 1 is 0.1mm-1mm.
The utility model adopts the alternating current 220V power supply, to different short-circuit resistances, regulates suitable output voltage with pressure regulator.Output terminal directly connects two leads of mutual short circuit in the cable.Two steel balls are serially connected with in the circuit, mix up the gap between the steel ball, the high electrical breakdown clearance air between two steel balls discharges.The sound that sends according to discharge is again regulated output voltage, and it is continuous that discharge is formed, " whip " sound that interval time is very short.At this moment, the electric current that cable short circuit point passes through makes this some heating, thereby finds this point exactly, makes its corresponding measures.The utility model makes countless short circuit cable obtain saving, and has obtained appreciable economic benefit.
