Description
Technical field
The utility model relates to the servicing unit of a kind of electric operating vehicle safety work, particularly a kind of electric operating vehicle earial drainage monitor.
Background technology
In electric operating process, need to use some electric operating vehicles, as crane, overhead vehicle, aerial lift device with insulated arm etc.The arm of crane of these working trucks, insulation bucket arm or lifting table are all moving components; when operation; electric operating vehicle moving component often can close to electrified body; distance between electric operating vehicle moving component and electrified body can not meet safe distance requirement time; electric operating vehicle can produce discharge current; in order to job safety; when electric operating; electric operating vehicle need have ground wire; discharge current flows out through ground wire; if the ground connection of ground wire is bad, the entail dangers to operating personnel safety when discharge current is larger.
In prior art, when electric operating, the distance between electric operating vehicle moving component and electrified body can not meet safe distance requirement time, do not have corresponding device that operating personnel can be reminded to take measures, therefore there is potential safety hazard.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, propose a kind of when electric operating, when can not meet safe distance requirement between electric operating vehicle moving component and electrified body, the electric operating vehicle earial drainage monitor of discharge current value can be sent, when solving electric operating vehicle operation in prior art, there is the problem of potential safety hazard.
The technical solution of the utility model is as follows:
Electric operating vehicle earial drainage monitor, current transformer and reometer offset, and the two ends of current mutual inductor coil are connected with the output electric contact of current transformer, export electric contact and are connected with the input electric contact of reometer; The outside surface of current transformer and reometer is set with circumferential band.
Described current transformer is annular or square.
The top of described current transformer arranges support platform, and support platform is provided with circular groove, and circular groove and winding wire directly match.
Described circumferential band structure is, the both sides of top board connect the stripe board that bottom is circular arc, and the circular arc-shaped bottom portion of stripe board stretches out link, and link is fastened by bolts.
Radian and the current transformer radian of the circular arc-shaped bottom portion of described stripe board match.
Be set to L-square bottom described stripe board, right angle stripe board and square electric current transformer match.
Described reometer is indicator type current meter or digital ammeter.
The utility model has the advantages of as follows:
The utility model is when electric operating, when can not meet safe distance requirement between electric operating vehicle moving component and electrified body, discharge current value can be sent, remind operating personnel to take to remove measures, allow electric operating vehicle moving component away from electrified body in time, ensure electric operating safety.

Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, concrete structure of the present utility model is described in detail.
embodiment 1
As Figure 1-4, electric operating vehicle earial drainage monitor, the top of ring current transformer arranges support platform, reometer is placed in support platform, support platform is provided with circular groove, circular groove and winding wire directly match, and the two ends of current mutual inductor coil are connected with the output electric contact of current transformer, export electric contact and are connected with the input electric contact of reometer; The outside surface of current transformer and reometer is set with circumferential band; Ring current transformer and reometer are trapped among in the ring of circumferential band by circumferential band, described circumferential band structure is, the both sides of top board connect the stripe board that bottom is circular arc, radian and the current transformer radian of the circular arc-shaped bottom portion of stripe board match, the circular arc-shaped bottom portion of stripe board stretches out link, and link is fastened by bolts.
Described reometer is indicator type current meter or digital ammeter.
embodiment 2
As shown in Figure 5, described current transformer is square electric current transformer.Be set to L-square bottom the stripe board of described circumferential band, right angle stripe board and square electric current transformer match.Other structure is with embodiment 1.
During installation, current transformer of the present utility model is enclosed within the ground wire of electric operating vehicle, namely allows the ground wire of electric operating vehicle through the endoporus of the utility model current transformer.
During use, in electric operating process, when can not meet safe distance requirement between electric operating vehicle moving component and electrified body, have discharge current in the ground wire of electric operating vehicle to pass through, then the output electric contact of current transformer can export induced current, after induced current flows through reometer, reometer can show the current value by reometer.
The above know-why being specific embodiment of the utility model and using, any based on the equivalent transformation on technical solutions of the utility model basis, all belong within protection domain of the present utility model.
