To explain the present invention, it is not intended to limit the present invention.
For sake of convenience, hereinafter so-called " preceding " " rear " " left side " " right side " "upper" "lower" and attached drawing itself it is forward and backward, left,
The right side, upper and lower direction are consistent, but do not play restriction effect to structure of the invention.
It please refers to Fig.1 to Fig.3, now insulation detection device provided by the invention is illustrated.Insulation detection device, including
Megameter 1 and testing agency 2.
Testing agency 2 includes rack 27, lead screw 21, screw 22, detector 24 and two brackets for support electroscope 3
23.Rack 27 is at opening groove profile, and two brackets 23 are separately fixed at the both ends of rack 27, and bracket 23 is equipped with for top and electroscope
3 compatible semicircle or long semicircular indentations, which can be with support electroscope 3.The lead screw 21 passes through bearing combination etc.
Common form is connect with rack 27, is connected with detector 24 with 22 top of screw of 21 threaded engagement of lead screw, and detector 24 can be with
Using bonding, the common connection type such as tight fit, threaded engagement is connect with screw 22.Detector 24 and screw 22 can together with
The rotation of lead screw 21 and translating.
Detector 24 includes detection plate 241 and two detection rings 242, and detector 24 passes through detection plate 241 and 22 phase of screw
Even.The detection plate 241 is made of isolation material to guarantee to insulate between two detection rings 242, and such isolation material can be
Common bakelite, resin, rubber etc. on the market, it is preferred that the present embodiment uses material of the insulating resin as detection plate 241.
Detecting ring 242 is the ring structure being adapted to 3 insulating bar of electroscope, and is made of conductive material, this conductive material can be city
Common copper, silver, stainless steel etc. on face, it is preferred that material of the present embodiment using copper as detection ring 242 detects 242 ring of ring
The inner ring size of shape structure is preferably with the outer diameter of 3 insulating bar of electroscope at tight fit or excessively cooperation, to guarantee to detect ring 242
Most anchor rings of contact 3 insulating bar of electroscope can be covered.The ring structure of detection ring 242 also extends downwardly out parallel two
A facade 2421 is fixedly connected using the facade 2421 that bolt and nut can will test ring 242 with detection plate 241.Two detection rings
242 be fixed on side by side detection plate 241 form a detector 24, two detection rings 242 respectively with two activating terminals of megameter 1
It is connected.Generally, a detection ring 242 is connected by conducting wire with the end " L " of megameter 1, another detection ring 242 passes through conducting wire
It is connected with the end " E " of megameter 1, can so carries out insulating properties to the part that 3 insulating bar of electroscope detects between ring 242 at two
It can detection.
The megameter 1 of the present embodiment is tampered megameter 1, specifically: the shaft of rocking handle 11 and the testing agency 2
The input shaft 211 of lead screw 21 is connected, i.e. the power source of also making lead screw 21 of rocking handle 11.And the screw pitch of lead screw 21, screw 22 also answers root
It is set according to the revolving speed of rocking handle 11 when 1 normal use of megameter, guarantees to shake rocking handle 11 screw 22 when working normally megameter 1
Movement speed will not be too fast.When operation, 3 insulating bar of electroscope is first passed through to the detection ring 242 of detector 24, and by electroscope
3 are placed on bracket 23, then manually shake the rocking handle 11 of megameter 1, while detector 24 is also from one end of 3 insulating bar of electroscope
It is moved to the other end, i.e., the insulation performance of 3 insulating bar of electroscope is detected, the insulation performance of 3 insulating bar of electroscope is detected
It is whether qualified, then compared with the judgment criteria phase for manually shaking test 3 insulating bar insulating properties of electric appliance in technology using common megameter
Together.Structure of the embodiment of the present invention is simple, and whole operation process only needs a people, simple and quick, time saving compared with the prior art
It is laborsaving.
Further, the testing agency 2 further includes energy sliding rail 25, and bracket 23 can move back and forth on sliding rail 25 with suitable
The electroscope 3 of different length is answered to carry out Insulation monitoring on the present embodiment.Sliding rail 25 is fixed in rack 27, the section of sliding rail 25
For " convex " type, bracket 23 is equipped with the groove matched with 25 section of sliding rail " convex " type.Optionally, it can be avoided for realization detector 24
It can also directly socket-connect with electroscope 3 after sliding rail 25, the groove of " convex " type or bracket 23 that can make sliding rail 25 is made into bias
Form, then so that the detection plate 241 of detector 24 is made into curve form to avoid sliding rail 25.
Further, the sliding rail 25 is equipped with the gap 251 that detector 24 can be made to pass through, this structure can guarantee detector 24
It socket with electroscope 3 and is not interfered with sliding rail 25.
Further, the detector 24 further includes the adjustment ring 243 of two arcs, and the adjustment ring 243 is set to detection
It inside ring 242, and is connect with adjustment screw 244, adjustment screw 244 is connect by screw thread with detection ring 242.Adjustment ring 243 is
The preferably soft aluminium of electric conductivity or copper foil, to be preferably bonded 3 insulating bar of electroscope, this structure, which can guarantee, is adjusting adjustment spiral shell
The case where silk 244, the detector 24 of the present embodiment is made to can be suitably used for 3 insulating bar of electroscope of different outer dimension sizes.
Further, clutch is equipped between the shaft of the rocking handle 11 of the megameter 1 and the input shaft 211 of the lead screw 21
Device.Megameter 1 does not need testing agency 2 generally in the independent rocking handle 11 for detecting, shaking megameter 1 sometimes for detection
Screw 22 is mobile, Gu setpoint clutch is in case the shaft of rocking handle 11 and the input shaft 211 of the lead screw 21 can divide when needed
From.
Further, the testing agency 2, which is additionally provided with, translates the feed rod 26 playing the guiding role, the light to the screw 22
