Description
Technical field
The present invention relates to power equipment quality surveillance equipment design field, is tested more particularly to the distribution transforming of temperature warning type short
Connection device.
Background technology
, it is necessary to which transformer terminal is terminated in some transformer test projects, short-circuit loop is formed, is measured.It is short
Connection device is exactly each terminal of short circuit, bears the Special wiring of short circuit current.For example DC Resistance Test of Transformer, idling carry examination
Test, in the experiment of temperature rise test, short-circuit ability to bear, short-circuit device needs to bear several amperes to the electricity of hundreds of even upper kiloamperes
Stream.To ensure to test the accuracy of safety and test measurement result, it is desirable to which short-circuit device resistance itself and contact resistance are smaller more
It is good.But the method that we commonly use is to be wrapped in soft copper metal silk in transformer terminal, short circuit loop is formed.This method
Shortcoming is clearly：First, it is dangerous.Winding by hand, does not seek unity of standard, and 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 is wound, it can not ensure to contact
Resistance, can not precise determination short circuit loop sectional area, therefore cannot be guaranteed short-circuit device resistance in controlled range, becoming
Measurement result is influenceed in depressor D.C. resistance, empty load test.3rd, it is inconvenient.Need the method for study knot setting fastening, short circuit dress
It has been usually easily to form fast knot afterwards to put, and can not untie, waste time and energy.Fish mouth forked type short-circuit device has already passed through improvement, even
More secure is connect, but still there is a situation where inaccurate and inconvenient：First, it is inaccurate.Fish mouth is pitched conductive with transformer
It is connected on the inside of bar only bayonet socket, less than 20mm on the inside of contact area only bayonet socket2, larger current can not be carried, measurement essence can not be ensured
Parasexuality.2nd, it is inconvenient.Need to use spanner during installation, fitted bolt cap washer uses, relatively cumbersome during installation.3rd, it is uncomfortable
With.The terminal of two kinds of forms of screw bolt-type and copper bar plate can not be adapted to simultaneously.Although two kinds of short-circuit devices recited above we make
It is higher with rate, but can not solve the problems, such as that safety problem is accurate with testing result all the time, thus can there is an urgent need to one kind
Solve the device of problem described above, while more intelligent, more rationalize, applicability is stronger, and conveniently device is replaced
Two kinds of devices recited above.
The content of the invention
The purpose of the present invention is that to solve the above problems and provides temperature warning type distribution transforming experiment short-circuit device.
The present invention is achieved through the following technical solutions above-mentioned purpose：

Hand-tighten bolts, the permanent magnetism insulating support are internally provided with high strength permanent magnet iron, glass fibers are connected with above the high strength permanent magnet iron
Pillar is tieed up, the glass fibre pillar is wrapped up by compound full skirt, and the glass fibre post top portion is fixed with U-shaped support, the U
Type support is clamped in above copper cash respectively, is wrapped up outside the copper cash by warming insulating barrier, the end of copper cash three is connected to
Crimp head, the hand-tighten bolts are through the inside of the crimp head, and the top board and the connection of lower platen centre are
Hand-tighten bolts are stated, top is inlaid with the high temperature helmet outside the crimp head, and the high temperature helmet is internally provided with copper
Warm bucket is guided, the copper leads warm bucket and is internally provided with compression spring, and the compression spring vertical direction is connected with ceramic cap, institute
State and wrapped up outside ceramic cap by alloy hoop.
In said structure, it is not necessary to original nut on transformer binding post is removed, can be directly by the crimping headgear
On binding post or wiring copper coin, now ensure that the top board crimps by force with the lower platen plate by the hand-tighten bolts
That spends is certain, and the alloy hoop has temperature memory function, and normal temperature is in deflated state, tightly wales the ceramic cap, when temperature reaches
During to 110 DEG C, expand according to shape memory when processing, integral thinned, internal diameter, now the ceramic cap can be released, described
It is raised in the presence of compression spring, in alarm condition, red pigment is mixed when now the ceramic cap is processed in process,
It is more eye-catching when ensuring to alarm, while the ceramic cap possesses heat-proof corrosion resistant erosion characteristic, the what is more important material temperature is swollen
Swollen coefficient is very small, will not lead to not alarm of takeofing because of the ceramic cap high-temperature expansion, in addition the top board band
There is the high temperature helmet, the high temperature helmet takeoffs when temperature is more than 110 DEG C, exposes red warning part, reminds and make
Industry personnel's platen temperature is too high, should stop testing, and checks wiring.
In order to further improve Detection results, the copper cash is compressed by copper hoop with the crimp head and connected, the upper pressure
Plate is tightened by the hand-tighten bolts with the lower platen and is connected.
In order to further improve Detection results, the high strength permanent magnet iron sticks in the top of the glass fibre pillar, institute
Stating U-shaped frame bottom adhesion has the glass fibre pillar.
In order to further improve Detection results, the hand-tighten bolts are connected through a screw thread with the top board, and the hand is twisted
Bolt is connected through a screw thread with the lower platen.
In order to further improve Detection results, ceramic cap described in the alloy hoop banding, the copper lead warm bucket with it is described
Compression spring is connected by adhesion.
Beneficial effect is：Convenient and swift, strong applicability, standard also be present in addition to automating positive effect in the present apparatus
The advantages that exactness is high, safe and reliable.
