Description

Technical Field

[0001] The utility model relates to the technical field of battery core capacity test, in particular to a battery core capacity test jumper device. Background Art

[0002] In the capacity test of lead-acid batteries in the DC system of a hydropower station, when a battery needs to be immediately removed due to insufficient capacity or quality problems, the battery's own connection line is generally used for jumper connection, such as Figure 7 and Figure 8 shown.

[0003] Normally, if only one battery is abnormal, you can use the jumper cable that comes with the battery set, which is about twice as long as the normal battery connection cable. After the jumper, the battery set will continue to discharge. Since the battery weighs about 40kg and is placed on a double-layer battery rack of 80cm, it is not easy to move. Therefore, during the test, the battery is temporarily placed in place after it is out of operation and will be replaced after the test is completed.

[0004] If multiple batteries are abnormal in succession, there is no matching jumper wire, which will affect the subsequent battery capacity test; if the cable is temporarily made, it is necessary to make a cable head that matches the battery terminal. If the cable is too long and crosses the battery, the cable's own weight will pull the cold head of the voltage and temperature sampling line on the battery terminal and cause the battery terminal to be stressed. See the schematic diagram Fig. 9 (Each battery pole is connected to a voltage collection line and a temperature collection line). Utility Model Content

[0005] The purpose of the utility model is to provide a battery core capacity test jumper device. When working, the whole device is placed outside the battery pack, and the two conductive seats are connected by a strip conductor. Then the jumper can be completed through the original battery jumper wire, avoiding the problems in the prior art. In order to achieve the above technical features, the purpose of the utility model is achieved as follows:

[0006] A battery core capacity test jumper device comprises an insulating rail, the insulating rail is provided with a groove, a strip conductor is installed in the groove, the extension direction of the strip conductor is consistent with the extension direction of the groove, two conductive seats contacting and cooperating with the strip conductor are slidably installed in the groove, and a jumper wire is connected to the strip conductor through the conductive seat.

[0007] The conductive seat comprises a body, on which a terminal for connecting a jumper wire is arranged, and the terminal is connected to the strip conductor through the body.

[0008] The side wall of the groove is provided with a first clamping portion, and the side portion of the body is provided with a second clamping portion adapted to the first clamping portion.

[0009] It also includes a flexible connector, which is used to bind the conductive seat and the insulating guide rail.

[0010] The flexible connector is one of an elastic cloth strip, an insulating tape and a cable tie.

[0011] The strip-shaped conductor is a conductive copper bar.

When working, the whole device is placed outside the battery pack, and under the action of external force, the two conductive seats 3 can slide in the groove 11, wherein the spacing between the two conductive seats 3 is determined according to the number and position of abnormal batteries, the two conductive seats 3 are connected by the strip conductor 2, and then each is connected to the battery through the original battery jumper wire. Compared with the prior art, there is no need to make an additional extended jumper wire, and the operation is convenient; at the same time, it also avoids the problem that when the extended jumper wire is too long and crosses the battery, the cable's own weight will pull the cold head of the voltage and temperature sampling line on the battery terminal and cause the battery terminal to be overstressed.

[0027] Furthermore, the conductive base 3 includes a body 31 , on which a terminal 32 for connecting a jumper wire is disposed, and the terminal 32 is connected to the strip conductor 2 through the body 31 . The body 31 is made of a conductive metal, preferably copper.

The first clamping portion 11a and the second clamping portion 31a are clamped together, so that the installation and matching of the conductive seat 3 and the insulating guide rail 1 can be further positioned. It should be noted that when the first clamping portion 11a is a convex, the second clamping portion 31a is the groove that matches it. Figure 2-4 On the contrary, when the first clamping portion 11a is a groove, the second clamping portion 31a is the protrusion that matches it. Figure 5 .
