Description
Technical field
The utility model relates to high-tension switch cabinet technical field, is specifically related to a kind of movable electricity testing device.
Background technology
High voltage electric equipment needs maintenance after operation a period of time, when overhaul of the equipments starts, in order to ensure personal safety, first must verify that whether switch cabinet main loop is charged, after determining that major loop is not charged, then galvanic circle ground connection.
In traditional grounding scheme, generally after switch cubicle has a power failure, operating personnel open cabinet door, manually open cabinet valve, then stretch into cabinet with electrical verification rod and touch main copper bar, observing on electrical verification rod whether have charged prompting, after confirmation major loop does not have electricity, earth connection is fixed in main conductive circuit, and then inspection switch cabinet.
But thisly manually directly play out cabinet valve, the method for artificial electrical verification is dangerous, easily causes electric shock accidents, and labour intensity is large, and at least two people coordinate and just can complete.
Utility model content
The technical problems to be solved in the utility model: existing high voltage electric equipment needs maintenance after running a period of time, method is after switch cubicle has a power failure, operating personnel manually open cabinet valve, artificial electrical verification, after confirmation major loop does not have electricity, earth connection is fixed in main conductive circuit, and then inspection switch cabinet.But the method for this people direct cabinet valve mechanism is very dangerous, if because of carelessness, just there will be personal safety.And this method labour intensity is large, wasting manpower and material resources.
In order to solve above technical problem, the technical solution of the utility model is as follows: a kind of movable electricity testing device, comprise sensing device, display unit, also comprise chassis vehicle, fixed frame, tactility apparatus insulator, conductive contact arm, insulating cover, Mume flower contact, the first grounding copper bar, the second grounding copper bar;
Described fixed frame is arranged on above chassis vehicle;
Described fixed frame is provided with tactility apparatus insulator;
One end of described conductive contact arm connects Mume flower contact, and the other end connects tactility apparatus insulator;
One end that described conductive contact arm connects tactility apparatus insulator is provided with insulating cover;
One end that described conductive contact arm connects tactility apparatus insulator connects the first grounding copper bar;
The bottom surface of described chassis vehicle is provided with the second grounding copper bar;
The first described grounding copper bar is electrically connected the second grounding copper bar.
Further, described chassis vehicle is provided with valve push pedal.
Compared with prior art, the beneficial effects of the utility model: the utility model movable electricity testing device does not need people to contact cabinet valve, after power failure of breaker, promote chassis vehicle movable electricity testing device is moved from test position to service position, the Mume flower contact of handcart directly contacts the fixed contact of cabinet, and whether movable electricity testing device meeting automatic gauging main conductive circuit is charged, solves people and directly opens cabinet valve problem, ensure that personal safety, reduce the amount of labour.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is chassis vehicle; 2 is fixed frames; 3 is tactility apparatus insulators; 4 is conductive contact arms; 5 is Mume flower contacts.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment: movable electricity testing device, comprises sensing device, display unit, also comprises chassis vehicle 1, fixed frame 2, tactility apparatus insulator 3, conductive contact arm 4, insulating cover, Mume flower contact 5, first grounding copper bar, the second grounding copper bar; Fixed frame 2 is arranged on above chassis vehicle 1; Fixed frame 2 is provided with tactility apparatus insulator 3; One end of conductive contact arm 4 connects Mume flower contact 5, and the other end connects tactility apparatus insulator 3; One end that conductive contact arm 4 connects tactility apparatus insulator 3 is provided with insulating cover; One end that conductive contact arm 4 connects tactility apparatus insulator connects the first grounding copper bar; The bottom surface of chassis vehicle 1 is provided with the second grounding copper bar; First grounding copper bar is electrically connected the second grounding copper bar.
Wherein, chassis vehicle is also provided with valve push pedal.
Wherein, the voltage condition on main conductive circuit experienced automatically by sensing device, and is transferred to device display screen, and this part belongs to existing known technology and is not described in detail.
Volume of the present utility model is little, and structure is simple, and cost is low, effective, plays the effect of protection personal safety.After power failure of breaker, promote handcart and move to service position from test position, the moving contact of handcart directly contacts the fixed contact of cabinet, and like this, major loop is from Mume flower contact---contact arm---first grounding copper bar---the second grounding copper bar ground connection handcart.Solve the problem that people directly touches major loop, ensure that personal safety.
