Sulfur hexafluoride gas (SF)6) Is an excellent insulating medium and is widely applied to the power industry. SF6The gas pressure in the equipment normally requires a certain pressure value to ensure the insulation performance, and if the rated value is lower, the equipment cannot work normally. SF6Insulated electrical equipment is influenced by factors such as product processing, mounting process, running time and environment, and the air leakage defect of different degrees often appears, leads to the inside insulating properties of equipment to descend, influences the normal operation of equipment daily, needs electrified tonifying qi. According to the national grid company "high-voltage switchgear operating Specification" and documentation, SF6The gas pressure drop to the alarm value is characterized as a serious defect. Thus, SF6When the gas pressure of the equipment drops between the alarm value and the rated value, the gas must be supplemented to the rated value.
At present, when manual air supplement is carried out, the air bottle is required to be carried more trouble. The operation of using the steel bottle shallow transport steel bottle is also very inconvenient, generally needs two people to operate (if, control the shallow alone, another person moves the steel bottle to the shallow), occupies and consumes more manpower and physical power, has danger factor. And the gas supplementing personnel sometimes need to lift the gas cylinder for multiple times to measure the gas cylinder, so that a statistical table of the use condition of the sulfur hexafluoride gas is filled in, and the gas cylinder is beneficial to masteringSF6Gas inventory is time consuming and labor intensive. Therefore, it is necessary to design a steel cylinder cart which can directly weigh the steel cylinder without manually moving the gas cylinder to move the position, and can grasp the total mass of the gas in the steel cylinder in real time, and can grasp the SF in time6The gas make-up quantity and the residual quantity are convenient to record. However, the road conditions of some roads in the substation are not good, the ground is uneven, and the trolley is difficult to be vertically erected on a horizontal plane. If the cart stands on an inclined plane, the weighing device and the steel cylinder on the cart are in an inclined state, so that the gravity of the steel cylinder cannot be perpendicular to the bearing surface of the weighing device on one hand, and the steel cylinder is easy to lean against other mechanisms, so that the weight of the steel cylinder is dispersed on parts except the weighing device, and the weighing device measures the weight of the steel cylinder to generate deviation.

3. Comparison of tests
As shown in fig. 3, the weighing device adopts a cantilever type measurement principle, when the cart is located on an inclined ground, the inclination angle of the ground is α, and the stress detected by the weighing device is as shown in formula (1).
F＝G×Lcosα (1)
In the formula: f represents the force detected by the weighing device, N.m; g represents the total weight of the gripping and lifting mechanism and the steel cylinder, N; l represents the arm length of the weighing device, m; alpha denotes the angle between the weighing device and the horizontal.
According to the formula (1), the larger the included angle between the weighing device and the horizontal plane is, the larger the deviation of the value measured by the weighing device from the real value is.
The contrast test that adopts No. 1, No. 2 steel bottle shallow to carry out, No. 1 steel bottle shallow is the shallow of this embodiment, and No. 1 steel bottle shallow is ordinary steel bottle shallow. Comparative tests using cylinder carts # 1 and # 2 were performed and the error from the actual cylinder weight was calculated and the results are shown in the table below.
Measuring accuracy of steel cylinder cart No. 11 and No. 2 in table on different inclined ground
Figure BDA0003243565950000061
As can be seen from the above table, the weighing result of the steel cylinder cart No. 1 accurately weighed horizontally on the ground with different inclination angles is basically unchanged; the weighing result of the common steel bottle carrying cart No. 2 is greatly influenced by the ground inclination, and the inclination is larger, so that the error is larger.
