Description
Technical field
The present invention relates to transformer detection technique field, the Hi-pot test more particularly to a kind of detection of for transformer is controlled
Tool.
Background technique
Transformer safety performance test is mainly manifested on insulation resistance, each winding of transformer and winding and magnetic core, electrostatic
Pressure is greater than 1000 megaohms to insulation resistance between shielded layer under routine, should not be low after hot test and constant temperature heat test
In 10 megaohms, the DC voltage for testing insulation resistance is 500 volts.
Voltage-withstand test, primary and secondary windings, magnetic core, should be able to bear between electrostatic layer virtual value be 50 hertz,
3500 volts of voltage effect, can bear the electricity that virtual value is 50 hertz, 1000 volts between secondary windings and magnetic core, electrostatic screen layer
Pressure effect, and without breakdown and arcing, while also wanting current limit.
Two channels of conventional transformer test fixture can be tested, but we test magnetic core in use
Silicon steel sheet between mutually insulated effect when, it finds that, after being tested with A channel, then when being tested with channel B, just need
It to be adjusted position to magnetic core, just can be carried out validity test, use is extremely inconvenient, is unfavorable for producing, and it is a large amount of to generate waste
The case where working hour, efficiency are extremely inefficient.
Summary of the invention
The purpose of the present invention is being directed to existing issue, a kind of Hi-pot test jig of for transformer detection is provided.
The present invention is achieved by the following technical solutions: a kind of Hi-pot test jig of for transformer detection, including
First TCH test channel and the second TCH test channel, first TCH test channel and the second TCH test channel are copper chaff, the first test
Channel is parallel with the second TCH test channel and interval is fixed on test board, and first TCH test channel one end is welded to connect by scolding tin
The high voltage power supply that jig provides, second TCH test channel one end are welded to connect conducting wire one end, other end connection second by scolding tin
Test pen, second TCH test channel other end ground connection, jig draw the first test pen outward.
As further improvement of these options, the conducting wire is copper wire, with the after the tin plating processing in copper wire one end
The connection of two TCH test channels, the copper wire other end is connect with the second test pen, and carries out proof and electric leakage-proof safety processing to it.
As further improvement of these options, magnetic core side is placed on first passage or second channel, with
Two test pens or the first test pen contact the silicon steel sheet of each composition magnetic core one by one, check that mutual silicon steel sheet whether there is
Electrical communication, access situation, can determine whether that the magnetic core is unqualified if it exists, otherwise qualified.
As further improvement of these options, armature winding or secondary windings one end are placed in first passage or
On two channels, contact secondary or armature winding coil ring road one by one with the second test pen and the first test pen, check two around
Mutual ring road between the mutual coil of group whether there is electrical communication, and access situation, can determine whether that the magnetic core is unqualified if it exists,
Otherwise it is qualified.
The present invention have the advantage that compared with prior art it is simple with structure, design rationally, thinking novel and unique, this
Added second test pen of jig, without exchanging when using the first TCH test channel and the second TCH test channel detection magnetic core and coil
Position, two channels can be used, and effectively increase employee's yield, improve benefit and efficiency.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The following further describes the present invention with reference to the drawings.
As shown in fig. 1, a kind of Hi-pot test jig of for transformer detection, including the first TCH test channel 3 and second
TCH test channel 4, first TCH test channel 3 and the second TCH test channel 4 are copper chaff, the first TCH test channel 3 and the second test
Channel 4 is parallel and interval is fixed on test board 2, and 3 one end of the first TCH test channel is welded to connect what jig provided by scolding tin
High voltage power supply 1,4 one end of the second TCH test channel are welded to connect conducting wire one end by scolding tin, and the other end connects the second test pen 5,
Second TCH test channel, 4 other end ground connection, jig draw the first test pen 6 outward.
As further improvement of these options, the conducting wire is copper wire, with the after the tin plating processing in copper wire one end
The connection of two TCH test channels 4, the copper wire other end is connect with the second test pen 5, and carries out proof and electric leakage-proof safety processing to it.
As further improvement of these options, magnetic core side is placed on first passage or second channel, with
Two test pens or the first test pen contact the silicon steel sheet of each composition magnetic core one by one, check that mutual silicon steel sheet whether there is
Electrical communication, access situation, can determine whether that the magnetic core is unqualified if it exists, otherwise qualified.
As further improvement of these options, armature winding or secondary windings one end are placed in first passage or
On two channels, contact secondary or armature winding coil ring road one by one with the second test pen and the first test pen, check two around
Mutual ring road between the mutual coil of group whether there is electrical communication, and access situation, can determine whether that the magnetic core is unqualified if it exists,
Otherwise it is qualified.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
