Description
Technical field
The present invention relates to the voltage-withstanding test method of cable, particularly a kind of group-type voltage-withstanding test method.
Background technology
At present, for guaranteeing the safety in utilization of cable, before dispatching from the factory, need the proof voltage of cable is carried out sampling Detection, existing method of testing mostly is greatly: cable is positioned in the container that is loaded with conducting medium, make conducting medium be surrounded on cable around, and adopt high-voltage generator to the cable high-pressure, whether detection streamer exists defective, wherein conducting medium adopts water mostly, and this kind method has simple and easy to do, tests advantages such as accurate.But, this kind method of testing is only applicable to the detection to the cable with water proofing property insulation course, and its external insulation of cable that is applied to compressor set at present adopts the fibrage layer mostly, do not possess water resistance, be soaked in the damage that will cause cable in the water, therefore be not suitable for existing voltage-withstanding test method.And cable different from the past is taken a sample test, and this kind cable must all be detected the proof voltage of every cable before dispatching from the factory, and its test block quantity is big, and traditional method of testing can not satisfy proof voltage group's survey requirement fast of this cable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of easy to operate, accurate testing, tested cable not damaged, the group-type voltage-withstanding test method of test cable proof voltage fast.
A kind of group-type voltage-withstanding test method comprises tested cable is positioned over step in the test container conducting medium, and adopts the step of pressue device to tested cable pressurization, and the step of detection streamer defect situation is characterized in that: further comprising the steps of:
Cable arranged be pencil, adopt conductive material to interconnect conducting the conductor of one end;
In test container, lay certain thickness steel ball and form the steel ball layer as conducting medium;
The cable that arrangement is pencil is positioned in the test container, and the cable detection section is fallen into oblivion in the steel ball layer;
The high-pressure side of pressue device is connected in the conductor of cable, and the earth terminal of pressue device is inserted in the steel ball layer in the container.
And described cable is for being arranged in parallel.
And the diameter of described steel ball is below the 3mm.
And described steel ball is the mixed body of the steel ball of diameter in 1～3mm.
And: the height of described steel ball layer is 10～100mm.
Advantage of the present invention and good effect are:
1. this method of testing adopts little footpath steel ball as conducting medium, overcome and adopted conducting liquid can't carry out the drawback of voltage-withstand test as the method for testing of conducting medium in the past the cable that insulation course does not have a water resistance, during test cable is fallen into oblivion in the steel ball layer, steel ball can contact with the outside surface of tested cable well comparatively all sidedly, therefore can form the electric field that is evenly distributed, meet test request, it is very convenient to operate.
2. this method of testing is the setting that is arranged in parallel of tested cable, and connects conducting in its end, can test simultaneously many cables, shortens detection time, improves detection efficiency, shortens the process time of product in the workshop, thereby increases economic efficiency.
3. this method of testing adopts steel ball as conducting medium, the steel ball testing result that its diameter is more little is accurate more, but going out cost and operability considers, when satisfying to detect under certain size, diameter of the steel ball gets final product when requiring, the preferred steel ball of the present invention is the following steel ball of diameter 3mm, and can adopt the mixed body of the steel ball in 1～3mm, it can be realized fully and the contacted purpose of tested cable outside surface.
4. method of testing design science of the present invention is reasonable, easy and simple to handle, detection efficiency is high, testing result is accurate, is a kind of group-type voltage-withstanding test method that has than high innovation character.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of group-type voltage-withstanding test method, comprise tested cable 3 is positioned over step in test container 5 conducting mediums, and the step that adopts 1 pair of tested cable of pressue device to pressurize, the step of detection streamer defect situation, its innovative point is: this method is further comprising the steps of:
The cable arrangement is pencil, as shown in Figure 2, adopt conductive material 8 to interconnect conducting the conductor of one end, be specially: an end part aligning that cable is provided with terminal 2, and be arranged in parallel, adopt conductive material that the terminal that cable end connected is connected successively and make its mutual conduction.
In test container, lay certain thickness steel ball 9 and form steel ball layer 4 as conducting medium, diameter of the steel ball more little itself and the contacted point of tested cable outside surface are also just many more, electric field is even more, the accuracy of test is also just high more, consider for factors such as saving cost, the diameter of steel ball is preferably below the 3mm, also can be the mixed body of the steel ball of diameter in 1～3mm, when the steel ball that varies in size is mixed mutually, its steel ball 10 than minor diameter can be filled up in the space that the major diameter steel ball forms, increase the contact point of steel ball and tested cable surface thus, improve measuring accuracy, cost is low when all adopting little steel ball simultaneously, and the height of steel ball layer is 10～100mm, be as the criterion to fall into oblivion tested cable, with 20～50mm the best.If when adopting the steel ball that varies in size to test,, should carry out disturbance to the steel ball layer after use after a while, make it fully mixed, eliminate lamination.
Arrangement is the cable parallel laid of pencil in test container, the cable detection section is fallen into oblivion in the steel ball layer, reach the outside surface purpose that steel ball is wrapped in each bar cable comprehensively, and, the end that cable is provided with terminal is exposed to outside the steel ball layer, therefore the other end need place its support steel ball layer outside owing to there is the cut ring that exposes cable core.
The high-pressure side 6 of pressue device is connected on the conductor of terminal of cable, the earth terminal 7 of pressue device is inserted in the steel ball layer in the container.Regulate pressue device, magnitude of voltage is set, open pressue device, the Cables for Dam Observation test mode in case the cable proof voltage is undesirable, when punch-through occurring, has shownly on pressue device, perhaps produces electric discharge phenomena in test container.At last, the undesirable cable of proof voltage is arranged, promptly return job shop and do over again as finding.
