Description
Technical field
The utility model belongs to experiment fixed equipment technical field, and in particular to a kind of to improve low-voltage circuit breaker experiment
The structure of stability.
Background technology
In electrical power distribution apparatus, low-voltage circuit breaker is used to distribute electric energy and protection circuit and equipment from failures such as overload, short circuits
Harm.With the increase of power consumption and the development of high-power electric appliance, the various indexs of breaker are all constantly improving, especially
It is the raising for being resistant to index in short-term, requirement to breaker also more and more higher, the raising so each producer also all tries every means
Short resistance to index.And for omnipotent breaker, short resistance to test is a pith in type approval test.National regulations test institute
The small then several kilo-amperes of electric current being passed through, then power supply is fixed and then are connected to tens kilo-amperes, inlet-outlet line with experiment copper bar bolt greatly.By electromagnetism
Field theory is understood, electric power can be produced between adjacent phase copper bar, if adjacent row electric current is equidirectional, conductor stress is attracting, if
It is opposite direction that adjacent row, which is passed through electric current, then conductor stress is repelled each other.Due to the copper bar that the electric current being passed through is alternating current, then adjacent phase
Or also changed over time by repulsion or by suction constantly repeatedly, electric current is bigger, and caused electric power is also bigger.Current many manufactures
For business when carrying out breaker cranking test, experiment copper bar is hollow out state, and this is not to be consistent with breaker realistic application conditions
's.Experiment copper bar itself is relatively long, and for arranging the experiment copper bar being formed by connecting by several sections, is then easier by electrodynamic
Influence, if can not be well secured, then the outlet row of breaker in itself then can by experiment copper bar constantly left and right
Pull, easily loosening causes loop temperature rise is too high seriously be able to can then be broken, and ultimately results in test failure.
The content of the invention
Technical problem to be solved in the utility model is：There is provided and a kind of overcome electric power to testing the traction of copper bar to carry
The structure of height experiment stability.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：One kind improves low pressure open circuit

End is fixedly installed supporting table, the first positioning hole is provided with the table top of the supporting table, the low-voltage circuit breaker passes through first
Positioning hole is fixedly mounted in supporting table, is correspondingly arranged on fixed station on the inside of the support, epoxy is provided with the fixed station
Supporting plate, is provided with the second positioning hole in the plate face of the epoxy supporting plate, the both ends of three three-phases test copper bars respectively with it is low
Outlet row, the power supply copper bar of voltage breaker are fixedly connected, and ring is mounted by means of bolts in the middle part of the three-phase test copper bar
In second positioning hole of oxygen supporting plate, three three-phases test the both ends of copper bar and middle part is fixedly connected by cleat insulator.
Preferably, it is bolted fixation between the three-phase test copper bar and cleat insulator.
Preferably, at least provided with three not in the first positioning hole of same straight line on the table top of the supporting table.
Preferably, fixation is installed by way of welding between the supporting table and support.
Compared with prior art, usefulness of the present utility model is：Three-phase copper test mining fixes middle branch with three
Support, i.e., it is connected with the outlet row of low-voltage circuit breaker at one, middle part is fixed with epoxy supporting plate, another place and power supply copper bar company
Fixation is connect, therefore three-phase test copper bar is fixed, electric power suffered by low-voltage circuit breaker outlet row influences then to substantially reduce, effectively
Improve experiment stability, validity.
