Abstract
The invention provides a contact sensing device capable of achieving a short circuit ground wire on-line monitoring. According to the contact sensing device capable of achieving the short circuit ground wire on-line monitoring, a fixing iron sheet, a contact crimping spring and a contact crimping sheet are fixed in an original clamping opening moving contact. A contact 1 and a contact 2 are respectively arranged on the contact crimping sheet and the fixing iron sheet. The contact sensing device capable of achieving the short circuit ground wire on-line monitoring enables the short circuit ground wire to send 'on-line' signals under an application state instantaneously, easily and conveniently and is capable of warning workers to understand immediately an installment position and an installment number of the on-line short circuit ground wire, and then the workers can know the conditions well, and the occurrence of an accident that the ground wire is switched on to supply power can be avoided.
Description
Technical field
The present invention relates to the power supply safety production field, a kind of contact sensing device of realizing the short-circuit grounding wire on-line monitoring specifically,
Background technology
In the maintenance work progress of electric system, short-circuit grounding wire plays an important role as the technical equipment of when maintenance protection maintainer, electrical equipment, safe operation of electric network.Along with the continuous expansion of electrical network scale, being on the increase of electrical equipment, during the electric system maintenance, the use of short-circuit grounding wire is more frequent, and usage quantity is also increasing.In real work, forget and remove short-circuit grounding wire and the electric power accident of " band ground wire combined floodgate power transmission " is of common occurrence, brought potential safety hazard for grid maintenance, operation of power networks, workmen.
Summary of the invention
The invention provides a kind of contact sensing device of realizing the short-circuit grounding wire on-line monitoring.
The present invention is achieved in that in original jaws moving contact it is contact 1, contact 2 that one contact is respectively arranged on contact compressing piece and fixed iron piece by hold-doun nut fixedly fixed iron piece, contact crimp spring, contact compressing piece.
The invention has the beneficial effects as follows: can easyly immediately make the short-circuit grounding wire that is in application state send " online " signal, remind instant installation position, the quantity of understanding online short-circuit grounding wire of staff, make the staff accomplish to know what's what, avoid the generation of " band ground wire combined floodgate power transmission " accident.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
In figure 1, the jaws static contact, 2, the jaws moving contact, 3, the jaws bracing frame, 4, the jaws steady arm, 5, get an electric shock 1,6, get an electric shock 2,7, contact compressing tablet spring, 8, the contact compressing piece, 9, hold-doun nut 1,2,10, fixed iron piece, 11, the jaws spring, 12, sending and receiving ray road.
Embodiment
As shown in the figure, by hold-doun nut (9) fixedly fixed iron piece (10), contact crimp spring (7), contact compressing piece (8), on contact compressing piece (8) and fixed iron piece (10), a contact being arranged respectively is contact 1(5 in original jaws moving contact (2)), contact 2(6).
When short-circuit grounding wire is in unused state, former device jaws spring is in state of nature, jaws moving contact (2) relies closely with jaws static contact (1), contact crimp spring (7) on jaws moving contact (2) is also in state of nature, contact 1(5) with contact 2(6) separate, cut-off the emission circuit, show that on wireless reception equipment this short-circuit grounding wire is in " not using " state.
Claims (1)
1. contact sensing device of realizing the short-circuit grounding wire on-line monitoring, it is characterized in that, by hold-doun nut fixedly fixed iron piece, contact crimp spring, contact compressing piece, it is contact 1, contact 2 that a contact is respectively arranged on contact compressing piece and fixed iron piece in original jaws moving contact.
