Abstract
The utility model relates to a tester for the electric line leakage of motor vehicles, which is composed of a signal generator part, a signal receiver part and a display part. A signal generator is provided with two line structures which are respectively suitable for the detected motor vehicles with two different voltage. The utility model has a working principle that signal current is sent to a line with faults, when the current flows across a bonding iron position, the bonding iron position can be searched according to the change position of measured magnetic field intensity. The utility model has the characteristics of high speed, accuracy and no damage to line sheath, and changes the detection method of dismounting contact point drawing lines in a large range by judging according to experience in the past. The utility model has the advantages of small size, simple structure and reliable performance.
Description
The utility model relates to design of motor circuit electric leakage (being commonly called as " bonding ") detecting instrument and manufacturing technology field.
At present, for the detection at motor circuit electric leakage position, all be rule of thumb to judge, dismantle contact on a large scale, twitch the method for the inspection of line, therefore, efficient is very low.
The purpose of this utility model provides a kind of novel motor circuit detection of electrical leakage instrument, and characteristics are that detection speed is fast, and is accurate, not the lesion wire skin.
The utility model line construction as shown in drawings; Constitute by the two large divisions.A part is the signal generator part, and another part is that signal receives, the display part.
The signal generator part-structure as shown in Figure 1; Comprise current relay, pilot relay, resistor, sounder and power supply tuner.
Signal reception, display part structure are as shown in Figure 2; Comprise split core type current transformer and display.
The utility model signal generator partly has two kinds of line constructions.Be that power supply A is first line construction when being 12 volts, used when being 12 volts of voltages to adapt to detected vehicle.When power supply A is 24 volts second line construction, used when being 24 volts to adapt to detected vehicle.
Signal generator first line construction is as shown in Figure 3: power supply A(12 volt) connect the lower gear of 1,2,3 switches in three or three sections switches, the 1st, 2 switches connect each resistance, R wherein

Above separation member is connected on the insulated circuit plate, in the box of packing into, draws A, B, four lead-in wires of E, F.
Signal reception, display part line construction are as shown in Figure 4; Connect four silicon diodes by split core type current transformer L, is connected with resistance R again, connect little as display, formation loop again by the table gauge outfit.
Ultimate principle of the present utility model is that a marking current is sent in the circuit that breaks down, and the bonding position as long as record faulty line change of magnetic field strength position, can be found in the electric current bonding position of also certainly will flowing through in faulty line so.
Using method of the present utility model is, according to machines such as detected vehicle accumulator voltages, if promptly tested vehicle be 12 volts and promptly use first circuit, be 24 volts as tested vehicle, then use second circuit.At this moment, the detecting device knob is transferred on the gear identical with its voltage, then energized A(positive pole), F end (negative pole) connects iron.At this moment, the detecting device pilot lamp is shinny, (if 12 volts, R
5Pilot lamp is bright, if 24 volts, R
6, R
5All bright), then signal output part B is connect iron, control end lead-in wire E touching connects iron, if sounder Yx sounding illustrates that sensors work is normal.The B termination goes in the tested faulty line to go then.Clamp test line with split core type current transformer again, connect iron with the touching of E end again, measure.When marking current flow through faulty line, the microampere meter gauge outfit of receiver showed stronger marking current reading, otherwise can not show then that than the heavy current reading this detecting device then is to judge " bonding " position according to the shows signal size of current.
Because the motor vehicle circuit is comparatively complicated, major part all is to pass the privileged site of body, therefore, detects comparatively difficulty of electric leakage position.Adopt the utility model can detect trouble location quickly and accurately.Overcome and dismantled contact in the past, twitched the method that circuit is searched, and grasped easily.
Accompanying drawing is the utility model line assumption diagram.
The utility model line component is standard and universal elements, with reference to instructions and accompanying drawing, presses electronics, instrument and meter industry known technology, can implement.
