Abstract
The utility model discloses an electrical insulation testing device, comprising turning switches from K1 to K120. One point of each turning switch is connected with a positive end of a megger in serial; three points of each turning switch are connected with a negative end of the megger in serial; two points of all the turning switches are sequentially connected with connecting points of an electric connector of 120 cores, and are respectively connected with various insulation testing points of the product through a process cable. The electrical insulation testing device solves the problems of large occupied device resources and high cost and the like for the existing testing device, and has benefits of simple structure, convenient use and maintenance, low cost and stable performance.
Description
Technical field
The utility model relates to a kind of electrical insulation testing device.
Background technology
At present, on high reliability commercial units such as space flight, aviation, when relating to unit and cable system Insulation test, generally all can select the cable tester of market sale for use, during test, need to be equipped with a large amount of corresponding frock interconnecting devices, when field testing, move inconvenience, it is big that this method takies device resource, with high costs.
The utility model content
For the Insulation test device resource that solves prior art is big, problem such as with high costs, the utility model purpose is to provide a kind of electrical insulation testing device.Utilize the utility model, realize simple and easy, efficient, reliable product electrical insulation testing.
In order to reach the purpose of above-mentioned utility model, the utility model is that the technical scheme that its technical matters of solution is adopted provides a kind of electrical insulation testing device, and this device comprises:
The input-output unit of Insulation test wrench device and insulation resistance test circuit;
Above-mentioned Insulation test wrench device comprises twist switch K1～K120,1 anode that is connected in series to a megohmmeter of each twist switch; 3 negative terminals that are connected in series to above-mentioned megohmmeter of each twist switch provide power supply and test two resistance between the insulating point for this proving installation by megohmmeter; 2 of all twist switch are connected to 1,2,3 of one 120 core electric connector successively ... on 120,, draw each Insulation test point of receiving product by the technology cable by this 120 core electric connector switching.
The utility model, a kind of electrical insulation testing device owing to take above-mentioned technical scheme, utilizes the characteristic of twist switch, according to mathematics permutation and combination C
120 1, by pulling twist switch, can measure certain a bit with respect to the insulation resistance of every other point, finish test function.The utility model can carry out the resistance test work of a large amount of insulating point, and efficient is greatly improved.Therefore, problem such as the utility model has solved prior art, and to take device resource big, with high costs, it is simple to have obtained product structure, and working service is convenient, and cost is low, beneficial effects such as stable performance.
Description of drawings
Accompanying drawing is the electrical schematic diagram of the utility model electrical insulation testing device.
Embodiment
Below in conjunction with description of drawings preferred embodiment of the present utility model.
Accompanying drawing is the electrical schematic diagram of the utility model electrical insulation testing device; Shown in the embodiment of accompanying drawing, this device comprises: the input-output unit (the latter half of accompanying drawing) of Insulation test wrench device (the first half of accompanying drawing) and insulation resistance test circuit.
Above-mentioned Insulation test wrench device comprises twist switch K1～K120,11 end (anode) that is connected in series to a megohmmeter of each twist switch; 32 ends (negative terminal) that are connected in series to above-mentioned megohmmeter of each twist switch provide power supply and test two resistance between the insulating point for this proving installation by megohmmeter; 2 of all twist switch are connected to 1,2,3 of one 120 core electric connector successively ... on 120,, draw each Insulation test point of receiving product by the technology cable by this 120 core electric connector switching.
Among the embodiment of the present utility model, above-mentioned twist switch is selected the KN6-102 trade mark for use, and electric connector is selected Y2-120ZJBM for use; Power supply by megohmmeter is given circuit supply, by artificial twist switch, realizes the test of insulation resistance, observes output resistance and can determine whether insulation resistance meets the requirements.
Below principle of work of the present utility model is described:
The product megger test be meant a cover certain insulating point in the product relatively and the insulation resistances of other all insulating point all should reach required value, be C with the permutation and combination of mathematics
120 2, this permutation and combination is come out the embodied in combination in twos of being had a few.
Among the utility model embodiment, the method for employing is to realize the test of insulation resistance by testing all insulating point with respect to other insulation resistances of having a few except that this point, and the permutation and combination of mathematics is C
120 1When the insulation resistance that tests out undesirable, be certain point and other insulation resistances of having a few when undesirable, adopt exclusive method to find out two points that do not meet the insulation resistance requirement, twist other switches successively, observe the method for insulation resistance and judge that the insulation resistance between which 2 is undesirable.
From the above mentioned, product structure of the present utility model is simple, and working service is convenient, and cost is low, and stable performance can also be carried out the insulating point megger test work of multiple spot, reliable test result, and efficient also is greatly improved.
