Embodiment
Below in conjunction with accompanying drawing, through embodiment the utility model is done to specify:
On gauge stand 9, crowngear 51 is installed, sector gear 52 is fixed on the crowngear 51; Be that crowngear 52 can drive sector gear 51 coaxial rotation; Power input crowngear 41 is inserted tube 4 (Fig. 1) with insulated tension pole and is fixedly connected, and insulated tension pole is inserted tube 4 and is hinged on the gauge stand 9, can freely rotate relative to gauge stand 9; Power input crowngear 41 is meshed with crowngear 51; Can drive crowngear 51 and rotate, in use, insulated tension pole inserted insulated tension pole insert in the slot of tube 4; Rotate insulated tension pole and can drive insulated tension pole slotting tube 4 (along directions shown in the arrow 101) and 41 rotations of power input crowngear, and then drive crowngear 51 (along direction shown in the arrow 102) and sector gear 52 rotations.Being fixed on the gauge stand 9 by the ferrimagnet making for magnetostatic 2, is to increase contact area; One end leaves triangular ramp, and magnetostatic 2 the other end is hinged through the end of axle 10 with magnetostatic 1, and axle 10 fixes with moving magnetic head 1; Axle 10 1 ends are fixed with sector gear 11; Sector gear 11 is meshed with sector gear 52, and sector gear 52 rotates and can drive sector gear 11 rotations (along direction shown in the arrow 103), makes magnetic head 1 rotation simultaneously; Thereby open clamp on amperemeter, the lead in loop to be measured is put into from the indentation, there of opening.When sector gear 11 and sector gear 52 no longer meshs, because sector gear 11 links to each other with back-moving spring 8 on the gauge stand 9, sector gear 11 turns round under the effect of back-moving spring 8; Thereby make magnetic head 1 and magnetostatic 2 closure; Form closed magnetic circuit, on magnetostatic 2, be with inductive coil 3, receive exchange current effect to be measured to produce induction current; Measured by current measuring device 6, can extrapolate the size of the electric current of surveying.Current measuring device is a reometer, and current data (or historical data, control data) wireless transmitter also is installed on it, and these data are received by the staff, see table thereby need not ascend a height, and promptly know size of current.Anti-reverse mechanism 7 contacts with crowngear 51, prevents crowngear 51 revolutions.
The foregoing description can be done following improvement, and promptly the slotting tube 4 of insulated tension pole is hinged on the gauge stand 9, and the top is equipped with point driving switch and triggers handle 408; Power input crowngear 41 is not inserted tube 4 with insulated tension pole and is fixedly connected; But directly link to each other with motor 12 (Fig. 4, motor 12 is by point driving switch control, point driving switch does not draw among the figure); Motor 12 is fixed on the gauge stand 9, and motor 12 provides energy by battery.Like this, only need that insulated tension pole is inserted insulated tension pole and insert in the slot of tube 4, hold up ammeter and rotate insulated tension pole, point driving switch triggers handle 408 and triggers the motor point driving switch, can realize opening the purpose with closed ammeter through the control motor rotation.
