Abstract

The invention discloses a grid bus current measuring device having the structure comprising a handle, a main box, an adjusting knob, a gas permeable net, a connecting mechanism, a measuring head, a measuring line, a sliding switch, an ammeter, a switch and a total power button. In the grid bus current measuring device, the connecting mechanism is arranged, and the measuring head has good connection effect and can be easily disassembled. During use, when connecting the measuring head, the connecting ends on the measuring line connected to the measuring head are inserted into an adapter, a manual rod is manually moved to the left to be hinged along a hinged support, a flat rod is driven to move over the connecting plate such that a T-rod hinged with the flat rod moves there-along, a pressingrod connected to the T-rod moves to the left in the tube, and conductive tabs on the pressing rod are attached to the left to push the connecting pieces in the recesses of the adapter to fully contact each other to complete the connection. Therefore, the connection method is simple and efficient, and the disassembly and accommodation of the measuring head are facilitated after use.

Description

technical field [0001] The invention relates to the technical field of current measurement, in particular to a power grid bus current measurement device. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, referred to as the power grid. The equipment for measuring the power current in the device. During use, the measuring head is connected through the lead wire in the device. After the connection, the metal conductor of the measuring head contacts the bus bar for measurement. After use, the measuring head is usually simply placed in the device. Above, the long-term idle exposure to the environment will cause more loss to the measuring head. On the one hand, there may be gaps in the connecting wire due to various reasons, causing safety hazards. On the other hand, the inside of the measuring head may be corroded due to factors such as moisture. With the em...
