Connection device is exactly each terminal of short circuit, bears the Special wiring of short circuit current.Such as DC Resistance Test of Transformer, idling carry examination
Test, temperature rise test, in the test of short-circuit ability to bear, short-circuit device needs to bear several amperes to the electricity of hundreds of or even upper kiloampere
Stream.To guarantee the accuracy of experimental safe and test measurement result, it is desirable to short-circuit device resistance itself and contact resistance it is more little more
It is good.But the method that we commonly use is wrapped in transformer terminal with soft copper metal silk, short circuit loop is formed.This method
Shortcoming is clearly：First, it is dangerous.Manual to wind, without seeking unity of standard, winding firmness cannot ensure, easily because of short circuit
Device comes off and causes discharge accident, jeopardizes personal equipment safety.2nd, it is inaccurate.When short-circuit device winds, it is impossible to ensure contact
Resistance, it is impossible to the sectional area in precise determination short circuit loop, therefore it cannot be guaranteed that the resistance of short-circuit device is in controlled range, becoming
Measurement result is affected in depressor D.C. resistance, empty load test.3rd, it is inconvenient.The method for needing to learn knot setting fastening, short circuit dress
Put has been usually easily to form fast knot afterwards, it is impossible to unties, wastes time and energy.Fish mouth forked type short-circuit device passes through improvement, even
More secure is connect, but still there is inaccurate and inconvenient situation：First, it is inaccurate.Fish mouth pitches conductive with transformator
It is connected on the inside of bar only bayonet socket, less than 20mm on the inside of contact area only bayonet socket2, it is impossible to carry larger current, it is impossible to ensure measurement essence
Parasexuality.2nd, it is inconvenient.Need to use spanner during installation, fitted bolt cap washer is used, relatively cumbersome during installation.3rd, it is uncomfortable
With.The terminal of screw bolt-type and copper bar plate two kind forms is adapted to simultaneously can not.Although two kinds of short-circuit devices recited above we make
It is higher with rate, but safety problem and the accurate problem of testing result can not be solved all the time, thus in the urgent need to one kind can
The device of problem described above is solved, while more intelligent, is more rationalized, the suitability is higher, conveniently device is replacing
Two kinds of devices recited above.
