Abstract
A kind of multifunctional ac contactor maintenance plate comprises plate sheet, T-shaped puller bolt, described plate sheet is a rectangular glass-epoxy plate, centre of surface place is provided with a through hole thereon, through hole both sides are respectively provided with a horizontal shallow slot, through hole one end is provided with a counterbore, through hole and counterbore with one heart, embed a nut in counterbore, T-shaped puller bolt does not have one end of counterbore to insert screw-in nut from through hole; After artificially dynamic iron core being promoted to be in " adhesive " state during use, multifunctional ac contactor is keeped in repair plate to insert the T-shaped puller bolt of turn in dynamic space between iron core and " obstruction cross-arm " and dynamic iron core is withstood make it to be in " adhesive " state all the time, just can decontrol the break-make of the main and auxiliary contact of hand measurement A.C. contactor, contact situation; The main and auxiliary contact of A.C. contactor and loop all intact, be only coil burnout and need power supply when as rescue and relief work, dynamic iron core is withstood making it to be in " adhesive " state and get final product emergency service.
Description
Technical field
The utility model relates to electrician tool, particularly a kind of multifunctional ac contactor maintenance plate.
Background technology
In electrical maintenance work, maintenance A.C. contactor is conventional work.When keeping in repair A.C. contactor, often need the iron core promoting clapper-type A.C. contactor to check break-make, the contact situation of main and auxiliary contact, iron core is promoted while checking universal instrument instruction break-make situation, for the A.C. contactor of such as CJT1 series, the serial larger volume of CJ12 as CJ12-600A A.C. contactor, need to apply very large strength and could promote iron core, usually need two people to work in coordination with; A people promotes iron core, people's measurement.And on-the-spot actual distribution box, power distribution cabinet are often less, almost can hold any more for two people's used times and test in the front side of A.C. contactor; So this kind of service work is often very poverty-stricken, be difficult to satisfactory carrying out.
Summary of the invention
The purpose of this utility model will solve in present electrical maintenance work exactly, above-mentioned poverty-stricken situation during maintenance A.C. contactor, there is provided a kind of multifunctional ac contactor to keep in repair plate, to reduce maintenance personal, improve the reliability of maintenance work, shorten maintenance time, reduce maintenance cost.
For achieving the above object, the utility model provides a kind of multifunctional ac contactor to keep in repair plate.
The utility model multifunctional ac contactor maintenance plate comprises plate sheet, T-shaped puller bolt, it is characterized in that: wherein said plate sheet is a rectangular glass-epoxy plate, centre of surface place is provided with a through hole thereon, through hole both sides are respectively provided with a horizontal shallow slot, through hole one end is provided with a counterbore, through hole and counterbore with one heart, embed a nut in counterbore, T-shaped puller bolt does not have one end of counterbore to insert screw-in nut from through hole.
Be described in detail with reference to accompanying drawing below in conjunction with embodiment.
Accompanying drawing explanation
Fig. 1 is the plate sheet vertical view of the utility model multifunctional ac contactor maintenance plate;
Fig. 2 is the plate sheet upward view of the utility model multifunctional ac contactor maintenance plate;
Fig. 3 is A-A direction view of Fig. 1;
Fig. 4 is the front view of the T-shaped puller bolt of the utility model multifunctional ac contactor maintenance plate.
Embodiment
The embodiment of the utility model multifunctional ac contactor maintenance plate is described in detail below in conjunction with accompanying drawing.
With reference to Fig. 1 ~ Fig. 3, the utility model multifunctional ac contactor maintenance plate comprises plate sheet 1, T-shaped puller bolt 2, it is characterized in that: wherein said plate sheet 1 is a rectangular glass-epoxy plate, centre of surface place is provided with a through hole 3 thereon, through hole 3 both sides are respectively provided with a horizontal shallow slot 6, and through hole 3 one end is provided with a counterbore 4, through hole 3 and counterbore 4 concentric, embed a nut 5 in counterbore 4, T-shaped puller bolt 2 does not have one end of counterbore 4 to insert screw-in nut 5 from through hole 3.
The use of the utility model multifunctional ac contactor maintenance plate is described below in conjunction with accompanying drawing:
Not having one end of counterbore to insert from through hole T-shaped puller bolt before the use of multifunctional ac contactor maintenance plate screws in nut, when overhauling the A.C. contactor of such as CJT1 series, the serial larger volume of CJ12, because the adhesive electromagnet of this kind of A.C. contactor is installed in side, the angle that the dynamic iron core of one " obstruction cross-arm " restriction opens all is had above dynamic iron core, spacing by " obstruction cross-arm " during the non-adhesive of dynamic iron core, there is a space during dynamic iron core adhesive and between " obstruction cross-arm ".Need during maintenance artificially dynamic iron core to be promoted to be in " adhesive " state, then measure the break-make of main and auxiliary contact, contact situation; Such as CJ12-600A A.C. contactor is often needed to apply very large strength and could promote iron core, usually need two people to work in coordination with; A people promotes iron core, people's measurement; Being keeped in repair by multifunctional ac contactor after artificially dynamic iron core being promoted to be in " adhesive " state in the dynamic space between iron core and " obstruction cross-arm " of plate insertion makes " obstruction cross-arm " be placed in horizontal shallow slot, dynamic iron core withstands and makes it to be in " adhesive " state all the time by the T-shaped puller bolt of turn, just can decontrol hand and measure.
Advantage and the good effect of the utility model multifunctional ac contactor maintenance plate are following 2 points:
1, keep in repair A.C. contactor: simple applicable safe and reliable, get final product complete operation owing to only needing a people; Poverty-stricken situation during maintenance A.C. contactor is improved, and decreases maintenance personal, improves the reliability of maintenance work, shortens maintenance time, reduces maintenance cost;
2, emergency service: when the main and auxiliary contact of A.C. contactor and loop all intact, be only coil burnout and need power supply when as rescue and relief work, now multifunctional ac contactor can be keeped in repair plate inserts in dynamic space between iron core and " obstruction cross-arm ", dynamic iron core withstands and makes it to be in " adhesive " state and get final product emergency service by the T-shaped puller bolt of turn, and this acts on may be more meaningful in real work.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
