Description

Technical Field

[0001] The invention belongs to the field of battery data measuring tools. Background Art

[0002] Under normal operating conditions, the voltage of the battery pack should be controlled within a specific range. If the battery voltage deviates from the standard value for a long time, the actual capacity of the battery will decrease, affecting its power supply ability in emergency situations. In addition, if the voltage of the single cells in the battery pack is unbalanced, it will accelerate battery aging and even cause the overall performance of the battery pack to decline. Therefore, regular battery single cell voltage testing is a very necessary maintenance measure.

[0003] The duty officer shall conduct a general battery voltage test (i.e., full battery voltage test) at least once a month for the substations under his jurisdiction. A substation of 110kV or above has at least one battery group, and the number of single batteries in each battery group can reach 104-108. The workload is large and the general test time is long. At present, the general battery voltage test tool is a multimeter. The distance between the two layers of batteries is less than the length of the test lead, and the space is small. The test lead is easy to tilt during measurement, and it cannot make good contact with the battery pole, resulting in errors. The measurement efficiency is low, and the positive and negative ends are far apart when measuring the floating charge voltage of the whole battery. Only one test lead can be held in each hand for measurement, which is inconvenient to read the multimeter reading. The batteries installed in the cabinet have two placement directions: the pole faces up and the pole faces out. When measuring the batteries located on the inside, the field of vision is still dim even if the lighting is turned on. It is impossible to accurately pass the test lead through the cover through hole for measurement. After extending the arm into the deep cabinet to measure multiple batteries, the fingers will become sore and weak, and it is easy to touch the positive and negative poles of the battery when touching, posing a safety hazard of personal electric shock.

[0043] Specifically, the LED light strip 11 is provided with a charging interface and can be charged via an external charging cable.

[0044] Specifically, the wire sleeve 5 is a corrugated telescopic structure with a maximum stretching length of 60 cm, and is made of PP material. In addition to the test lead 12 and the test lead probe 9, the test operating rod 1, the first switching mechanism 2, the second switching mechanism 3, the telescopic mechanism 4, the multimeter box 6, the test lead cover 35 and the like are all made of ABS material, which has the characteristics of high strength and good electrical insulation performance.

[0048] Specifically, by tightening or loosening the screw-on insulating sheath 17, the friction between the screw-on seat 24, the universal ball 15, and the screw-on insulating sheath 17 is increased or decreased, thereby adjusting and fixing the direction of the test operating rod 1.

By tightening or loosening the main rod insulating sheath 18, the friction between the main rod 19 and the main rod insulating sheath 18 is increased or decreased, thereby adjusting and fixing the length of the telescopic mechanism 4.

[0049] As an example, combining Figures 1 to 7 As shown, in this embodiment, the working process of the test operating rod 1 is:

[0050] The elastic pressing pieces 25 on the left and right sides of the rear end 23 of the buckle are pressed toward the rear end 23 of the buckle at the same time under the action of external force, so that the elastic pressing pieces 25 are out of contact with the surface of the unidirectional helical track 10, driving the buckle 8 to move freely in both directions on the unidirectional helical track 10 through the buckle moving groove 13, and then driving the test probe 9 to move freely in both directions on the test probe moving groove 36. When it moves to a suitable position, the elastic pressing piece 25 is released, so that the buckle 8 is connected to the unidirectional helical track 10 and fixed in position, and then the test probe 9 is fixed in position. According to the distance between the through holes of the cover on the positive and negative poles of the battery 34 to be tested, the distance between the two buckles 8 is adjusted, and then the distance between the two test probes 9 is fixed.

[0051] As an example, combining Figures 1 to 6 , Figures 8 to 13 As shown, in this embodiment, there are two ways to implement the measurement function. Method 1 is to measure the battery with the pole facing upward, and method 2 is to measure the battery with the pole facing outward. The specific process is as follows:

[0052] After removing the multimeter box cover 22, place the multimeter 7 in the multimeter box 6, and the wire 21 passes through the through hole of the internal partition of the multimeter box 6. After connecting to the multimeter 7 through the wire plug 30, the multimeter box cover 22 is closed. The screw-on insulating sheath 17 is loosened and tightened under the action of external force, so that the test operating rod 1 is adjusted and fixed around the universal ball 15; the adjustment handle 28 is loosened and tightened under the action of external force, so that the connecting arm 16 is adjusted and fixed around the rotating shaft 26; the main rod insulating sheath 18 is loosened and tightened under the action of external force, so that the extension rod 20 is pulled out of the main rod 19 and fixed. After adjustment, the test pen probe 9 is perpendicular to the multimeter 7 and downward, and the state is mode 1; the test pen probe 9 is parallel to the multimeter 7 and forward, and the state is mode 2. After turning on the light strip switch 14 to light up the LED light strip 11, remove the test pen cover 35. According to the distance between the through holes of the protective cover on the positive and negative poles of the battery 34 to be tested, move the buckle 8 to adjust the distance between the two test probes 9. Turn on the multimeter function button 31, adjust the multimeter gear adjustment handle 32 to a suitable gear, hold the multimeter box 6 with both hands to drive the test operating rod 1 to move through the first adapter mechanism 2, the second adapter mechanism 3, and the telescopic mechanism 4, press the multimeter box 6 down to make the test probes 9 pass through the through holes of the protective cover and plug into the poles of the battery 34, and then read the measurement data on the multimeter display screen 33. There is no need to adjust the position of the test probes 9 after that, just plug and measure in sequence.
