Abstract
The utility model is a kind of novel gun-type clamp on amperemeter, and gun-type support, current transformer, rectification circuit and the display circuit be made up of insulating material form; Current transformer is arranged on the front end of gun-type support by swivel adapter head; Range switch is arranged on the top of gun-type support handle, and reometer gauge outfit is arranged on above the body of a gun; Rectification circuit is arranged on gun-type internal stent.Because jaw can rotate, be convenient to comprise the wire under various situation, make gun-type clamp on amperemeter can adapt to various measurement place; During measurement, right hand gripping handles, thumb regulates range switch, selects suitable range; Forefinger detains binding clip trigger, makes jaw comprise tested wire, unclamps binding clip trigger, the registration of read current table, just can complete the surveying work to electrified wire well.
Description
Technical field:
The invention belongs to electricity field, exactly belong to electromagnetic measurement field.
Background technology:
Because the jaw of traditional clamp on amperemeter and reading dial are fixed in same plane, inconvenience is caused to the measurement of the electrical conductor under some special case, as the measurement of the electrical conductor to the horizontal direction higher than gauger, if not by the thing that ladder etc. is ascended a height, alone clamp on amperemeter will be difficult to surveying work; The handle of traditional clamp on amperemeter and jaw switch (namely trigger) are hereafter distant, are difficult to complete surveying work to electrified wire with a hand.For the problems referred to above, we devise gun-type clamp on amperemeter, just can complete the surveying work to electrified wire well, solve the problems referred to above satisfactorily with a right hand.
Summary of the invention:
The gun-type support that the utility model is made up of insulating material and current transformer mounted thereto, current commutates circuit and current display circuit form; Movable binding clip 6 and the fixed pliers head 9 of ferromagnetic material form jaw, when binding clip trigger 4 unclamps, form closed electromagnetic circuit; Add Secondary Winding 7 and measured conductor 8, form current transformer; Current transformer is arranged on the front end of gun-type support by swivel adapter head 10.Current Display is made up of reometer gauge outfit 1 and range switch 2; Range switch is arranged on the top of gun-type support handle 3, and when making right hand handle 3, thumb can conveniently stir range switch 2.Reometer gauge outfit 1 is arranged on above gun-type support, and with the plane orthogonal that handle 3 and binding clip trigger 4 are formed, be convenient to survey crew read registration.Current commutates circuit 11 is arranged on gun-type internal stent, the alternating current that electromagnetic transformer produces can be become direct current and export.The binding clip trigger 4 of gun-type support is connected with the movable binding clip 6 of current transformer by brake article 5; Two wires of connecting secondary winding 7 pass from the hollow of swivel adapter head 10, and as the input end of rectification circuit 11, meanwhile, the output terminal of rectification circuit 11 can be used as again the input end of display circuit.
Accompanying drawing illustrates:
Fig. 1 is the structural drawing of gun-type clamp on amperemeter:
Wherein 1-reometer gauge outfit; 2-range switch; 3-handle; 4-binding clip trigger; 5-brake article; The movable binding clip of 6-; 7-Secondary Winding; The tested wire of 8-; 9-fixed pliers head; 10-swivel adapter head; 11-rectification circuit
Fig. 2 is traditional clamp on amperemeter structural drawing:
Wherein 1-digital electronic ammeter gauge outfit; 2-range switch; 3-handle; 4-jaw switch; 5-fixed pliers head; The movable binding clip of 6-
Embodiment:
According to the trend of wire, rotate jaw, make jaw be convenient to comprise tested wire 8 on the one hand, make again eyes be convenient to observed reading reometer 1 on the other hand; The right hand holds gun-type clamp on amperemeter handle 3, thumb stirs range switch 2, range is transferred to maximum, and forefinger presses lower pliers head trigger 4, the movable binding clip 6 of gun-type clamp on amperemeter opens, send before gun-type clamp on amperemeter, make tested wire 8 in jaw central authorities, forefinger unclamps binding clip trigger 4, the jaw of gun-type clamp on amperemeter closes, Secondary Winding 7 loop produces alternating current of inducting, and through rectification circuit 11 rectification, is shown and read by reometer gauge outfit 1; As the half of the undercurrent maximum range of measurement, thumb stirs range switch 2, reduce range again to measure ... until measurement electric current exceedes the half of reometer gauge outfit 1 maximum deflection scale, the numerical value of read current, can reduce artificial error so to greatest extent.
