Abstract
The utility model discloses an ammeter, which comprises an ammeter head, a secondary winding, a core, a handle and a fixed handle, wherein the ammeter head is embedded into the fixed handle; the two ends of the secondary winding are connected to two contacts of the ammeter head respectively; the handle is connected with the core; and the fixed handle is connected with the core. The ammeter is simple in structure, convenient to operate and high in safety.
Description
Technical field
The utility model relates to a kind of reometer.
Background technology
Employed in the market reometer though also can accurately measure electric current, need be taken tested lead apart when measuring, and is connected with the contact of reometer, and operating process is comparatively complicated.
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, a kind of reometer that lead just can record electric current that need not to take apart to be provided.
Technical scheme: in order to realize above purpose, the described a kind of reometer of the utility model comprises the electric current gauge outfit; The secondary winding, iron core, handle; Fixed handle, described electric current gauge outfit is inlaid on the fixed handle, and described secondary winding two ends are connected on respectively on electric current gauge outfit two contacts; Described handle is connected with iron core, and described fixed handle is connected with iron core.
Security when guaranteeing that reometer uses, described fixed handle is an insulated handle.
Security when guaranteeing that reometer uses, described handle is an insulated handle.
In order to make operating personnel more comfortable in use, described fixed handle is provided with is convenient to the groove that the people holds.
In order to make handle can control folding unshakable in one's determination, described handle is connected with bearing pin with unshakable in one's determination.
Beneficial effect: a kind of reometer that the utility model provides, simple in structure, easy and simple to handle, safe.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1. electric current gauge outfit, 2. Secondary Winding, 3. iron core, 4. handle, 5. fixed handle.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of reometer comprises the electric current gauge outfit, the secondary winding; Iron core, handle, fixed handle, described electric current gauge outfit is inlaid on the fixed handle; Described secondary winding two ends are connected on respectively on electric current gauge outfit two contacts, and described handle is connected with iron core, and described fixed handle is connected with iron core, and described fixed handle is an insulated handle; Described handle is an insulated handle, and described fixed handle is provided with is convenient to the groove that the people holds, and described handle is connected with bearing pin with unshakable in one's determination.
If will measure the electric current of a lead, press handle 4 during use, just the expansible iron core 3, and the lead of tested electric current is put into the U-shaped pincers; Decontrol handle 4 then, unshakable in one's determination 3 is just closed, and tested lead is in the middle of the ring-shaped core 3; Because the electric current in the tested lead is an alternating current, so can produce alternating magnetic field around the lead, alternating magnetic field forms flux circuit through unshakable in one's determination 3; Because secondary winding 2 is wrapped on unshakable in one's determination 3, so alternating magnetic field can produce voltage through the coil of secondary winding 2 coileds, according to electromagnetic induction principle; Alternating magnetic field in unshakable in one's determination 3 can make secondary winding 3 two ends produce corresponding alternating voltage, because Secondary Winding 2 two ends are connected with two contacts of electric current gauge outfit 1, forms the loop; So produce corresponding exchange current in the loop, reometer gauge outfit 1 pointer shows numerical value, records current in wire.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
