Abstract
The utility model discloses a DC high-voltage forcipated current measuring device, which is suitable for directly measuring DC of electrical equipment under a voltage grade of 10kv and below without de-energizing. The structure of the device is that the device comprises an insulating operating rod and a DC forcipated current measuring device, and the DC forcipated current measuring device is mounted at the top of the insulating operating rod.
Description
Technical field
The utility model belongs to the measurement mechanism of electrical equipment, the pincerlike current measuring device of particularly a kind of high direct voltage.
Background technology
Present prior art is applicable to 600V rated voltage and following circuit measuring, does not also measure the device of DC current for the electrical equipment of dc rated voltage 10kV and following electric pressure, and the pincerlike current measuring device of high direct voltage will be filled up this blank.
The utility model content
The purpose of this utility model provides a kind of electrical equipment of dc rated voltage 10kV and following electric pressure that is applicable to needn't cut-off circuit, directly measures the pincerlike current measuring device of high direct voltage of the usefulness of DC current.
For achieving the above object, the utility model adopts following technical scheme:
The pincerlike current measuring device of a kind of high direct voltage, it comprises insulating bar and the pincerlike current measuring device two parts of direct current, the pincerlike current measuring device of direct current is installed in the insulating bar top.
The pincerlike current measuring device of described low-voltage direct is a clamp on amperemeter.
Described insulating bar is made up of outer layer insulation bar and primary insulation bar, and the primary insulation bar is sleeved in the insulating bar of the outside, and the primary insulation bar is connected with the jaw mechanism of the pincerlike current measuring device of direct current.
Utility model is made up of insulating bar and the pincerlike current measuring device two parts of direct current, and insulating bar is made up of inside and outside two-layer insulating bar, can open, close the pincerlike current measuring device jaw of direct current mechanism, thereby reach the measurement purpose.
The utlity model has following useful effect: when (1) surpassed 600V when voltage, the pincerlike current measuring device of conventional direct current can not have been measured it, and this device can be measured.(2) owing to need not to cut-off circuit, measure more convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. clamp on amperemeter, 2. outer layer insulation bar, 3. primary insulation bar.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, clamp on amperemeter 1 is installed in the insulating bar top, insulating bar is made up of primary insulation bar 3, outer layer insulation bar 2, primary insulation bar 3 is connected with the jaw structure of clamp on amperemeter 1, when primary insulation bar 3 is up, the moveable jaws of clamp on amperemeter 1 can be backed down, measured lead can enter the jaw of clamp on amperemeter from opening part; When primary insulation bar 3 is descending, the moveable jaws closure of clamp on amperemeter 1, thereby measure current value, measure finish after, operation primary insulation bar 3 is emitted measured lead from jaw.
