Description
Technical field
The utility model relates to a kind of proving installation technical field of disconnector, specifically a kind of automatic testing equipment mechanical life of double-column horizontal rotation type outdoor disconnector silver coating.
Background technology
The fingertip contact that electric system outdoor high-voltage isolating switch engages adopts copper silver-plated conventionally, be the disconnector deciding section of mechanical life the mechanical life of silver coating, this silver coating quality directly affects current-carrying capacity and the serviceable life of disconnector, if the silver-plated effect of fingertip or contact is bad, by causing, the resistance of fingertip contact is large, easily heating, the adverse consequencess such as accelerated oxidation, the equipment that there is no is at present tested it, therefore, determine that mechanical life of isolation switch contact fingertip silver coating is most important.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure, easy for installation in order to overcome above-mentioned defect, can automatically test the device of the mechanical life of double-column horizontal rotation type outdoor disconnector silver coating.
The technical solution adopted in the utility model is: a kind of automatic testing equipment mechanical life of double-column horizontal rotation type outdoor disconnector silver coating, comprise electric operating mechanism, the fingertip of gearing and disconnector, electric operating mechanism is connected with the fingertip of disconnector by gearing, it is characterized in that: also comprise automatic drive, automatic drive comprises the time relay, counter and display, time relay one end is connected with the control loop common point of electric operating mechanism by circuit, the other end of the time relay is connected with contactor, described counter one end is connected with the auxiliary switch contact A side of electric operating mechanism by circuit, the other end of counter is connected with contact B side with auxiliary switch by circuit, on counter, be provided with display.
The utility model has designed automatic drive and has been connected with electric operating mechanism, the time relay in automatic drive can be by the time interval of electric operating mechanism control disconnector divide-shut brake, counter can record the number of times of divide-shut brake, thereby the mechanical life of test disconnector fingertip or contact silver coating, counter shows number of times by display, for operating personnel's record and judgement, the time relay can also be controlled the time length of disconnector test, or the functions such as the condition of setting as required interrupt condition and proceed, divide-shut brake action in the utility model test process just can realize without manual intervention, automaticity is high, be convenient to install and use.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the structural representation of automatic drive in the utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise electric operating mechanism 2, the fingertip 1 of gearing and disconnector, electric operating mechanism 2 is connected with the fingertip 1 of disconnector by gearing, also comprise automatic drive 3, automatic drive 3 comprises the time relay 4, counter 5 and display 6, the time relay 4 one end are connected with the control loop common point of electric operating mechanism 2 by circuit, the other end of the time relay 4 is connected with contactor, described counter 5 one end are connected with the auxiliary switch contact A side of electric operating mechanism 2 by circuit, the other end of counter 5 is connected with contact B side with auxiliary switch by circuit, on counter 5, be provided with display 6, display 6 directly shows number of times.
When the utility model is used, according to product specification, the time relay 4 is set the interval time of test duration and divide-shut brake, the time relay 4 control electric operating mechanism 2 realize disconnector point, feed motion and divide-shut brake interlude, simultaneously, counter 5 records divide-shut brake number of times and directly shows divide-shut brake number of times by display 6, for operating personnel, records and judges that whether product is qualified.There are abnormal conditions or need to stop time, can hand off control device power supply or motor drive mechanism is transformed into manual mode, so no longer continue to send a deciliter instruction, action stops; The time relay 4 power supply kinds stop divide-shut brake action; In the time of need proceeding, switch on power or transfer motor drive mechanism to auto state, counter 5 sends instruction, and test job is proceeded.
The utlity model has simple and reasonable for structure, easy for installation, the feature that automaticity is high.
