And, approach switch in the contact site installation one of contiguous moving contact and fixed contact, on this, approach switch is fixedly mounted with by upper side wall in an over sling and switch cubicle, corresponding to the open mode of moving contact, on the support of the front end of spring, is fixedly mounted with approach switch.
Advantage of the present utility model and good effect are:
This grounding switch drives bull stick to rotate the action of divide/closing that realizes disconnecting link by motor and gear drive, whether by approach switch, detect grounding switch puts in place, then on switch cubicle display screen, shown, this structural design has reduced staff's working strength, has improved equipment dependability and fail safe.Meanwhile, retain original manual operation structure and check form, prepare against while needing manual operation and use and directly check.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is control circuit figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of novel grounded disconnecting link, comprise support 9, insulator 5, fixed contact 3, moving contact 4, copper earth tube 8 and bull stick 2, at the interval, upper surface of support, be fixedly mounted with three insulators, upper surface at each insulator is respectively fixedly mounted with a fixed contact, with each fixed contact corresponding matching, one moving contact is installed, in order to connect three moving contacts, at the laterally inserted copper earth tube in the lower end of three moving contacts, on the copper earth tube of corresponding each moving contact, be respectively set with an adapter sleeve 7, at the laterally inserted bull stick in the lower end of three adapter sleeves, on a left side, on the adapter sleeve of right both sides, each hinge fills a longitudinal spring 6.
Innovative point of the present utility model is:
One end of described bull stick passes switch cubicle 13, bull stick outer end in switch cubicle outside is set with a joystick 1, helical gear 12 in the coaxial connection one of inner end of the bull stick inside switch cubicle, on this, on helical gear and, bevel gear 14 is connected with a joggle, under upper bevel gear, be symmetrical arranged bevel gear 17 with upper bevel gear mirror image, this lower bevel gear and once helical gear 18 are connected with a joggle, and this lower helical gear connects motor 16 axles.Described upper bevel gear is connected by a vertical power transmission shaft 15 with lower bevel gear, is set with a bearing pedestal 19 in the bottom of power transmission shaft, and this bearing pedestal is packed on the upper surface of a brace table 20.
For the ease of what detect disconnecting link, open/close state, approach switch 10 in the contact site installation one of contiguous moving contact and fixed contact, on this, approach switch is fixedly mounted with by upper side wall in an over sling and switch cubicle; Corresponding to the open mode of moving contact, on the support of the front end of spring, be fixedly mounted with approach switch 11.
At cabinet outer side of door setting-in one control panel of switch cubicle, on control panel, be shaped with respectively and close button and minute button, this control panel connects control circuit and is shown opening of disconnecting link or closed state by display screen.
As shown in Figure 2, the utility model adopts threephase asynchronous machine to described control circuit, and in figure, resistance R A is plug braking resistance, also has the effect of limiting starting current simultaneously.BS1 and BS2 are respectively the normally opened contact that rotates and reverse of speed relay BS.This circuit working principle is as follows: press and close button SF2 (the utility model will close and be defined as forward), auxiliary relay KF3 coil electricity self-locking, its normally-closed contact is opened, interlocking auxiliary relay KF4 coil circuit, KF3 normally opened contact is closed, make contactor QA1 coil electricity, QA1 main contacts closure makes stator winding connect positive sequence three phase mains through 3 resistance R A, motor starts reduction of speed and starts, when motor speed rises to certain value, the forward of speed relay makes normally opened contact BS1 closed, make auxiliary relay KF1 energising self-locking, at this moment due to KF1, the normally opened contact of KF3 is closed, contactor QA3 coil electricity, so 3 resistance R A are by short circuit, stator winding is rated voltage in addition directly, motor speed rises.When detecting grounding switch, closes upper approach switch, while arriving assigned address, and co-bit sense switch SF1 action (a minute position sense switch is SF4), KF3, QA1, QA3 power-off in succession.Because the inertia rotating speed of rotor is now still very high, the forward normally opened contact BS1 of speed relay is not yet restored, auxiliary relay KF1 is still in running order, so after contactor QA1 normally-closed contact resets, contactor QA2 coil is just switched on, and its normally opened contact is closed, makes stator winding obtain negative-phase sequence three phase mains through 3 resistance, motor is carried out to plug braking, and motor speed declines rapidly.When motor speed is during lower than speed relay operating value, speed relay normally opened contact resets, KF1 coil blackout, and contactor QA2 discharges, and plug braking process finishes.Motor reverse starting is identical during with forward with braking procedure, repeats no more herein.
Operation principle of the present utility model is:
This grounding switch to the grounding switch of switch cabinet of converting station divide, closing operation carries out semi-intelligent design, when the closed disconnecting link of needs, press the button that closes on lower control panel, motor forward, motor shaft drives the bull stick of grounding switch to turn clockwise by gear drive, makes moving contact close to fixed contact, when upper approach switch detects moving contact and contacts with fixed contact to motor signal, motor stops, and synchronous signal is presented on display screen; When needs are opened disconnecting link, press minute button on lower control panel, motor reversal, motor shaft drives the bull stick of grounding switch to be rotated counterclockwise by gear drive, make moving contact away from fixed contact, when approach switch detects moving contact and puts in place instantly, to motor signal, motor stops, and synchronous signal is presented on display screen.
The utility model has retained the joystick mode of operation of original grounding switch, make this grounding switch can be manually also can automatic operation, range of application is wider, applicability is stronger.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
