Current measurement device added with lengthened operating handle

Abstract

The invention relates to the technical field of current measurement instruments, in particular to a current measurement device added with a lengthened operating handle. The current measurement devicecomprises a plier-type current meter and the telescopic operating handle, wherein the plier-type current meter is provided with a jaw button for opening a jaw of the plier-type current meter and a reading button for opening a reading locking key of the plier-type current meter. The plier-type current meter is connected to the top of the operating handle, and a movable handle is connected to the bottom of the operating handle. A transmission mechanism arranged in the operating handle is connected to a movable handle, the movable handle can downward pull the transmission mechanism to extrude thejaw button so as to open the jaw button or upward push the transmission mechanism to extrude the reading locking key so as to lock a reading of the plier-type current meter. When the current measurement device is used, an operator can achieve jaw button or reading button pressing by tightening or loosening the movable handle on the ground and does not need climbing rods for climbing a tower to approach wires and measure current, the current measurement device is safe and quick to operate and high in working efficiency, saves time and labor and can avoid electric shock and falling risk.

Description

technical field [0001] The invention relates to the technical field of current measuring instruments, and more particularly, relates to a current measuring device equipped with an extended operating handle. Background technique [0002] The clamp-type ammeter is composed of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is squeezed. When measuring, the operator directly opens the jaws of the clamp meter to clamp the wire under test and reads directly. Take the reading or directly lock the reading of the clamp meter manually and then read the reading. At present, when measuring current on low-voltage overhead lines, operators need to use clamp-type ammeters to measure current by climbing poles or towers close to the measured wires. The operation is time-consuming and laborious, and the work efficiency is low, and there is a certain risk of electric shock and falling. Contents of the invention [0003] The purpos...
