Description
Technical field
The present invention relates to switchgear technical fields, and in particular to a kind of switchgear dynamic/static contact contacts depth measurement device.
Background technology
Because high-tension switch cabinet is totally enclosed type, even narrow space in contact box when busbar has a power failure, handcart is shaken and is put
Operating position, O&M service personnel still can not contact situation to plum blossom fingertip and accurately be measured, be only capable of by opening busbar storehouse
Local range estimation;In addition, what is carried out in many cases is that busbar does not have a power failure handcart circuit breaker service work, bus bar side static contact band
Electricity, it is even more impossible to actual contact situation is confirmed by O&M service personnel;So it is typically only capable to consolidate to operating position by hand
Surely indicate a little, whether in place operating position indicator light is bright differentiates handcart, and also thermometric can not be carried out to contact position after operation;It is above-mentioned
Hidden danger easily brings the switchgear burnout failure caused by the bad fever of contact, so situation can not be contacted to plum blossom fingertip
It is switchgear factory inspection and acceptance to measure, insulating is transformed and a big hidden danger of daily O&M maintenance.
Applying date 2015.08.18, the patent of application number 201510507335.7 disclose a kind of switch cabinet handcart contact of knowing clearly
Depth measurement tools are contacted, the fixing piece including being installed on static contact outer surface is installed on moving contact outer surface and and fixing piece
The sliding component that is oppositely arranged and can automatic reading digital band tape;Digital band tape includes being installed on switch cabinet handcart cabinet
Housing on the inside of panel is built in the tape measure of housing, for carrying out the barcode scanner and and bar code scan of reading to tape measure
Device is connected the display screen for showing reading;Tape measure is equipped with the bar code that adjacent spacing is zero;One end of fixing piece is fixed on
It is the front end flush of the end of static contact, the other end and static contact, one end of sliding component and the front end flush of Mume flower contact, another
One end is connected with the beginning of tape measure, and the stretched length of tape measure is at least the axial length of Mume flower contact, the stretched direction of tape measure with
The axial direction of sliding component is identical.It realizes accurate reliable contacts, and the stroke of measuring device can be read.
Above device has the following problems:First, need to set fixing piece on static contact, be opened since the static contact is located at
Cabinet deep inside is closed, it is inconvenient for operation, it is also difficult to ensure that the fixing piece is concordant with the static contact front end;2nd, touched due to dynamic
The contact position of head is not in its not-go-end, and the front end of static contact is circumferentially provided with the chamfering in house type section so that described dynamic tactile
The critical contact position of head and static contact is the contact position of contact and chamfering end, therefore cannot fixing piece be mounted on stationary contact
Sliding component is mounted on moving contact end by head front end.
The content of the invention
