Embodiment Construction

[0009] As shown in the figure, in the original clamping movable contact (2), the fixed iron piece (10), the contact crimping spring (7), and the contact crimping piece (8) are fixed by the fixing nut (9). There is respectively a contact on the head crimping sheet (8) and the fixed iron sheet (10), i.e. contact 1 (5), contact 2 (6).

[0010] When the short-circuit grounding wire is in the unused state, the jaw spring of the original device is in a natural state, the jaw moving contact (2) and the jaw static contact (1) are close to each other, and the jaw moving contact (2) The contact crimping spring (7) is also in the natural state, the contact 1 (5) is separated from the contact 2 (6), and the transmitting line is disconnected, and the short-circuit grounding wire is displayed on the wireless receiving device as "unused".

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 [0001] The invention relates to the field of power supply safety production, in particular to a contact sensing device for realizing on-line monitoring of short-circuit grounding wires. Background technique [0002] In the maintenance and construction process of the power system, the short-circuit grounding wire plays an important role as a technical device to protect maintenance personnel, electrical equipment, and power grid operation during maintenance. With the continuous expansion of the grid scale and the continuous increase of electrical equipment, the use of short-circuit grounding wires is more frequent and the number of use is also increasing during power system maintenance. In actual work, it is not uncommon for power accidents to occur when the short-circuited grounding wire is forgotten to be removed and "connect the switch with the grounding wire to transmit power", which brings safety hazards to power grid maintenance, power grid operation, and...
