Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electricity testing equipment, specifically is a shake measuring device for insulating operating pole. BACKGROUND

[0002] The overhead contact system is an important part of the railway transportation system, which provides power supply for electric traction vehicles to enable the train to run normally. However, due to the working environment of the overhead contact system, it is easily affected by vehicle impact, weather environment, and debris interference, etc., which will make the various components of the overhead contact system become the prominent fault point in the railway power supply profession. When there is a fault on the overhead contact system or it is in some specific working conditions, the operating personnel need to use the debris pole, the electricity tester pole, the equipotential line pole and other insulating operating poles for maintenance. Although the insulating operating poles are put into use after safety testing, the insulating performance will decrease due to the high frequency of use. If the operating personnel use the insulating operating poles with substandard insulating performance, it will pose a threat to their personal safety. Therefore, it is necessary to detect the insulating performance of the insulating operating poles before use.

[0003] At present, the commonly used insulating performance detection methods mainly include the following two kinds: one is to set the use period of the insulating operating pole (usually half a year), and send the insulating operating pole to the repair test area for detection after the use period ends. However, this method relies on fixed detection time points and cannot timely find the problem of insulating performance decline. The second is to use megohmmeter for shake test by the operating personnel before actual use in the maintenance site. Although this method can realize real-time detection of the insulating operating pole, at least two people are generally needed to cooperate in the shake test at present, such as one person holding the megohmmeter and the other person holding the insulating operating pole. However, this form has the following limitations in actual application:

[0004] Firstly, the required labor cost is high and there is a risk of electric shock. Secondly, according to relevant regulations, the distance between the measurement points needs to be controlled during the shake test, but manual operation is prone to deviation, which cannot guarantee the accuracy of the shake test data. In addition, the terminal post of the megohmmeter directly contacts with the insulating operating pole in the existing shake test, which has small contact area and is not conducive to obtaining sufficient and accurate data, which will lead to repeated shake test and long shake test time.

[0028] For the main structure of the shaking device mentioned above, the following aspects should be considered when designing in detail:

[0029] 1) The width, length and thickness of the insulating plate 21 should be of appropriate size to ensure that the volume of the shaking support 2 produced meets the requirements; and the insulation strength of the insulating plate 21 should be controlled, one of which is the strength of the insulating plate 21 itself, and the other is the change range of the insulation strength of the insulating plate 21 under high temperature and high humidity conditions.

[0030] 2) The several semicircular metal rings 22 need to be arranged in a proper balance to ensure the accuracy of the detection data; and the specific material of the semicircular metal rings 22 should be selected, one requirement is that the weight of the semicircular metal rings 22 should not affect the overall weight of the shaking test support 2, and another requirement is to facilitate the post-processing and ensure the processing effect (mainly the connection operation between the insulating plate 21 and the connection firmness).

[0034] The working principle of the shaking test device provided in this embodiment is as follows:

[0035] The shaking test support 2 is used for placing the insulating operating rod 3, and the megohmmeter 1 is used for shaking test and data reading, thereby realizing detection of the insulation performance of the insulating operating rod 3. Specifically, in use, the support body I and the support body II are both laid flat on the ground, so as to place the insulating operating rod 3 on the support body I (or the support body II, and one of the support bodies is enough), and the inner surface of the semicircular metal ring 22 on the support body I can support the insulating operating rod 3; then the support body II is rotated to be buckled on the insulating operating rod 3, so that the support body I and the support body II jointly clamp the insulating operating rod 3 through the cavity in the middle; then the alligator clip connected to the L terminal post of the megohmmeter 1 is clamped to the conductive sheet 5 connected to the semicircular metal ring 22 belonging to the L group, and the alligator clip connected to the G terminal post of the megohmmeter 1 is clamped to the conductive sheet 5 connected to the semicircular metal ring 22 belonging to the G group, thereby completing the assembly operation before shaking the megohmmeter 1. Then, according to the relevant provisions, the megohmmeter 1 is shaken at a set rotating speed (120 r / min in this embodiment), so that the megohmmeter 1 reaches the rated voltage, which acts on the insulating operating rod 3. The insulation performance of the insulating operating rod 3 can be judged by observing the megohmmeter 1, that is, if the insulation performance of the insulating operating rod 3 is reduced to cause leakage, the pointer of the megohmmeter 1 will slightly swing back or directly indicate short circuit.

[0036] In the shaking test process, the insulating operating rod 3 is fixedly placed in the shaking test support 2, so the data measured at a certain moment only represents the insulation performance of the part of the insulating operating rod 3 currently located in the detection range. Therefore, the insulating operating rod 3 can be pulled and adjusted in the shaking test support 2 to detect other parts of the insulating operating rod 3. In addition, when the insulation performance of the insulating operating rod 3 is reduced or damaged, thereby causing the insulation value displayed by the megohmmeter 1 to be reduced or zeroed, the shaking test should be immediately stopped, and whether there is dirt or other substances on the surface of the insulating operating rod 3 that can cause the insulation performance to be reduced should be detected. If not, it can be judged that the insulation performance of the insulating operating rod 3 is not up to standard.

[0037] In summary, the shaking test device provided by the embodiment has the following advantages:

[0038] 1) The insulation performance of the insulating operating rod 3 can be detected, and the operator can directly judge the insulation performance according to the reading of the megohmmeter 1, so that the operator can find the problem in the first time, avoid the misuse of the unqualified insulating operating rod 3, and effectively protect the safety of the operator.

[0039] 2) The operator no longer needs to manually hold the insulating operating rod 3, thereby effectively saving labor costs and avoiding the risk of electric shock. In addition, the insulating operating rod 3 and the shaking test support 2 remain relatively stationary during the shaking test, so the shaking test distance does not change, thereby ensuring the scientific accuracy of the remote measurement data.

[0040] 3) megohmmeter 1 post with the conductive part is connected, so as to effectively increase the contact area, and then facilitate access to sufficient and accurate data, and do not need to repeat the shake test, can save detection time.

[0041] 4) device simple structure, and the cost and difficulty of making low, suitable for large-scale use.
