Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power supply and maintenance, in particular to a voltage sampling and electricity collecting clamp. Background Art
[0002] Sampling and drawing power from power generation equipment refers to obtaining electric energy samples from power generation equipment during the power generation process for monitoring, analyzing and controlling the operating status of power generation equipment. This method of sampling and drawing power is of great significance to ensuring the safe, stable and economical operation of the power system. There are several points to note when drawing power: Ensure safety: Before sampling and drawing power, the safety of personnel and equipment must be ensured. Operators should be familiar with relevant electrical knowledge and safety regulations, wear insulating protective equipment, and strictly follow operating procedures to select appropriate sampling points: The sampling points should be able to reflect the overall operating status of the power generation equipment. For different types of power generation equipment, the sampling points may be different. For example, for synchronous generators, sampling points can be set on the stator winding or rotor winding; for DC generators, sampling points can be set on the positive and negative poles of the output end. At present, during the maintenance of the power grid, it is necessary to detect the power supply parameters of the power generation equipment in order to connect to the existing power supply network. In the past, when sampling and drawing power from power generation equipment, most people wore insulating gloves and used crocodile clips to clamp them on the motherboard of the distribution box. Power sampling is performed on the busbar busbar; Problem 1: After the crocodile clip is clamped on the busbar busbar, the tail direction of the crocodile clip is parallel to the width direction of the busbar busbar, and the tail of the crocodile clip is easy to interfere with the adjacent busbar busbar, which poses a risk of phase short circuit; Problem 2: Since the structural form of the crocodile clip is an X structure, there are fewer actual clamping contact points between the crocodile clip and the busbar busbar. In actual use, poor contact occurs due to the linkage of the wiring, thereby affecting the accuracy of data collection; Problem 3: In the process of clamping the crocodile clip to the busbar busbar, it is necessary to pinch the tail of the crocodile clip with your hand and put your hand deep into the interval of the busbar busbar to achieve clamping; Although the operator wears insulating gloves, the internal space of some distribution boxes is limited, and the internal environment is relatively messy and complex. In the event of an operating error, the risk of electric shock caused by puncturing the insulating gloves still exists. In the prior art, there are multiple risks when the power generation equipment performs sampling and power sampling operations, and the safety and accuracy of power sampling are not enough. Therefore, a voltage sampling power clamp is provided. Utility Model Content
