[detailed description of the invention]
Referring to shown in Fig. 2 (a) and Fig. 2 (b), the present invention is that Cubicle Gas-Insulated Switchgear disconnecting switch is defeated
Many gyrations measurement apparatus of shaft, is mainly made up of pointer 1, toothed disc 2, angle dial 3, screw 4, bearing 5, magnet 6,
Described angle dial and toothed disc are coaxial；Measurement apparatus inhales the location A at disconnecting switch counter flange 200, institute by magnet 6
Stating toothed disc 2 to engage with disconnecting switch output shaft 100, modulus is identical, the ratio of toothed disc 2 and disconnecting switch output shaft 100 number of teeth
It is worth relevant with disconnecting switch output shaft 100 corner, it is therefore an objective to disconnecting switch output shaft corner more than 100 is changed by toothed disc 2
It is the corner within 360 °, thus realizes in 360 °, directly measure corner.Pointer is installed in order to measure on described toothed disc
The anglec of rotation of disconnecting switch output shaft.
Being provided with shrinkage pool on described magnet 6, be provided with bearing 5 in this shrinkage pool, described toothed disc 2 is through angle dial 3
Centre bore be connected with bearing 5.
Please referring specifically to Fig. 3 (a) and Fig. 3 (b), the one side of described toothed disc 2 is provided through the center of angle dial
Cylindrical boss B in hole, other end face is provided with the fixed part C of fixed pointers.The fixed part C of described fixed pointers uses
Cylinder bilateral symmetry trimming shape (i.e. forms two parallel rectangle planes in cylindrical two side symmetry trimmings, sees Fig. 3
Shown in shape shown in (a) center and Fig. 3 (c)).The hollow space of described toothed disc 2 uses double sector structure, on the one hand alleviates tooth
The rotating mass of wheel disc, still further aspect can be by this double-scallop-hole observation angle.
With the center of toothed disc 2 as initial point, axial as X-axis with toothed disc 2, with the radial direction of toothed disc 2 as Y-axis, described
Y-axis positive direction is pointed in 0 degree of position of angle dial 3, and described pointer 1 points to Y-axis positive direction.
Please referring specifically to Fig. 4 (a) and Fig. 4 (b), described angle dial 3 includes the dial being provided with angle lattice
And it being fixed on the connecting portion on disconnecting switch counter flange, described connecting portion is from the outward extending L-shaped of the one side of dial
Structure, this L-shaped structure is fixed by screws on disconnecting switch counter flange.
Installation method order below:
1., after disconnecting switch has been assembled, disconnecting switch output shaft 100 and counter flange 200 do separating brake respectively and surpasses
Contact open position when journey position and installation operating mechanism, is shown in Fig. 1；
The most first bearing 5 is loaded in the shrinkage pool of magnet 6, subsequently the magnet 6 having been charged into bearing 5 is inhaled in disconnecting switch transition
At A on flange 200, see Fig. 1；
3. positive Y direction is pointed in 0 degree of position of angle dial 3, with screw 4, angle dial 3 is fixed on isolation
On switch transition flange 200, see Fig. 2；
4. B platform on toothed disc 2 (i.e. cylindrical boss) is loaded in bearing 5 through the centre bore of angle dial 3, see
Fig. 2；
5. pointer 1 is enclosed within the C platform (i.e. fixed part) of toothed disc 2, and pointer 1 points to positive Y direction.
Main operational principle is:
First, each lattice on angle dial 3 is changed with disconnecting switch output shaft 100 gear ratio according to toothed disc 2
Calculate the angle of corresponding disconnecting switch output shaft 100, when disconnecting switch output shaft 100 and the number of teeth of toothed disc 2, modulus determine,
The angle of each lattice correspondence disconnecting switch output shaft 100 on angle dial 3 is unique.
Along with disconnecting switch output shaft 100 rotates counterclockwise, toothed disc 2 turns clockwise, and sees Fig. 2, because pointer 1 is to be enclosed within
Toothed disc 2, therefore pointer 1 turns clockwise along with toothed disc 2, and its anglec of rotation is identical with toothed disc 2 anglec of rotation, record
The anglec of rotation that stroke is corresponding with contacting travel, converts, and has both drawn disconnecting switch output shaft 100 anglec of rotation.
The main feature of patent of the present invention is as follows:
1. disconnecting switch output shaft gyration more than 100 is measured and can be completed in 360 °, reduces the impact of human factor, it is to avoid
Cause unnecessary mistake；
2. toothed disc 2 hollow space uses biparting shape, sees Fig. 3 (a), can alleviate toothed disc (rotating mass, and can be by double
Scallop hole observation angle；
3. see Fig. 3 (b), at the C end of toothed disc 2, use cylinder bilateral symmetry trimming shape, simple in construction, it is simple to assembling pointer
1, and pointer 1 can be realized rotate with toothed disc 2；
4. toothed disc 2 can be changed according to disconnecting switch output shaft 100 number of teeth, modulus and disconnecting switch stroke, with full
The rotation angle measurement of the disconnecting switch (many corners export structure) of foot different cultivars；
5. angle dial 3 can be changed according to disconnecting switch real space, to meet the disconnecting switch of different cultivars
The rotation angle measurement of output shaft (many corners export structure)；
6. magnet 6 can directly be inhaled on disconnecting switch counter flange 200, and assembly or disassembly is convenient, it is not necessary in disconnecting switch
Perforate on counter flange.
