Abstract
The utility model discloses an automatic parallel connection electric arc test apparatus comprising a pedestal and a blade. The blade is arranged on the pedestal. The automatic parallel connection electric arc test apparatus is characterized in that: the automatic parallel connection electric arc test apparatus also comprises a controller, a power supply, a mechanical transmission assembly, a stepping driver, a power line and an information feedback loop; the mechanical drive assembly comprises a motor and a slideway; the pedestal is supported on the slideway; the controller controls the motor through the stepping driver; the motor drives the pedestal to slide to and fro along the slideway; and the information feedback loop is connected with the controller. The power supply provides electric power for the whole test apparatus. The information feedback loop is used for collecting and giving feedbacks of motion information of the feedback mechanical drive assembly and the blade support blade so as to provide the information for the controller to carry out adjusting. According to the utility model, through the automation control of electric arc tests, the dangerous degree in test can be lowered, and the test process can be accurately controlled; the test success rate can be raised; the usage period of the blade can be prolonged; and material consumption can be reduced.
Description
Technical field
The utility model relates to the technical construction field of a contact arc test unit, refers to especially a kind of auto parallel Connection arc test device.
Background technology
Electric arc is a kind of gas discharge phenomenon, and the moment spark that electric current for example, produces by some insulating medium (air), is divided into serial arc and electric arc in parallel.Serial arc can be verified by carbonization Channel Test bench teat, and electric arc in parallel is mainly to verify by a contact arc test unit.Arc test in parallel is because test current is large, point electric arc produces and is not easy again to grasp, UL1699 standard has been stipulated a class point contact arc test unit, the nominal thickness of steel blade should be 1.27mm (0.05 inch), and size is about 32mm (1-1/4 inch) and takes advantage of 140mm (5-1/2 inch).If necessary, blade can be changed.Also allow blade sharper.Blade is installed on a band leverage, keep cutting angle producing " making blade and a conductor wherein produce solid contacts; and contact with another conductor generation electric arc " effect, but there is following defect in this class arc test device: 1. dangerous large, arc test in parallel is close to short-circuit test, and test current minimum current is 75A, and during test, electric spark disorderly spatters, easily produce secondary disaster, also easily injure the person; 2. press by hand lever arm, accomplish to make blade and a wire wherein to produce solid and contact, and to produce electric arc point contact gear ratio more difficult with another wire, due to factors such as the shake of hand, visual angles, necessary multi-pass operations is just once successfully tested.
Utility model content
The utility model technical issues that need to address are to provide a kind of safe, energy handled easily, increase success of the test rate, reduce blade loss, increase the auto parallel Connection arc test device in serviceable life.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of auto parallel Connection arc test device, comprise pedestal, blade, blade is located on pedestal, it is characterized in that: also comprise controller, power supply, mechanical driving, step actuator, energising circuit and information backfeed loop, described mechanical driving comprises motor and slideway, and abase frame is on slideway; Controller is controlled motor by step actuator, and motor driving pedestal slidably reciprocates along slideway, and information backfeed loop connects controller.Power supply is given whole test unit power supply, and information backfeed loop, for collecting and feed back the movable information of mechanical driving and knife rest blade, adjusts for controller.
Further, described pedestal comprises blade bearing, dog screw, and blade is connected with blade bearing by dog screw.Degree of tightness by screw regulates, and controls the angle of the upper-lower position of blade and the incision of blade.Blade is when doing experiment, excessive because of pickup current, easily cause breach, and the upper-lower position of adjustable blade can repeatedly utilize same blade, saves consumptive material.In addition, adjust the cut-in angle of blade, can meet the requirement that contacts of blade tangent plane described in standard and wire.
Further, in described information backfeed loop, there are several sensors.Multiple sensor provides the required controller that feeds back signal to, and controller is to motor command adapted thereto.
Compared with prior art, the utility model has following advantage:
One, controller can be controlled motor, according to setting program, rotates, and with movable knife rack, along the speed of user's demand, on slideway, moves.As want revision test, as long as click the button of controller, test unit just repeats last test, easy to operate, and can increase the Degree of Success of test.
Two, blade is connected with dog screw with blade bearing, by regulating dog screw, finely tunes the cut-in angle of blade, also can adjust the upper-lower position relation of blade, can avoid, because arc test causes damaged position, reaching the repeatedly utilization of blade, saves consumptive material.
Three, in signal feedback loop, there is sensor, data back knife rest being moved by sensor is to controller, controller in conjunction with these signals to motor command adapted thereto, make cutter or deceleration, or stop, or the action such as retreat, to reach cutter, contact with a conductor solid, contact with another root conductor electric arc, complete test.
Accompanying drawing explanation
The schematic diagram of Fig. 1 the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment mechanical driving.
Embodiment
Below in conjunction with drawings and Examples, further illustrate the technical solution of the utility model.
In conjunction with Fig. 1 and Fig. 2, the utility model relates to a kind of auto parallel Connection arc test device, comprise pedestal 1, blade 2, controller, power supply, mechanical driving, step actuator, information backfeed loop, described mechanical driving comprises motor 13 and slideway 3, and 1 of pedestal is on slideway 3; Controller is controlled motor by step actuator, and motor driving pedestal 1 slidably reciprocates along slideway 3, and information backfeed loop connects controller, and blade bearing 11 is equipped with in described pedestal 1 top, and blade 2 is fixing with blade bearing 11 by dog screw 12; In information backfeed loop, comprise some sensors, the required controller that feeds back signal to is provided.By dog screw 12 on blade 2 and blade bearing 11, the cut-in angle of fine setting blade 2, also can adjust the upper-lower position relation of blade 2, can avoid, because arc test causes damaged position, reaching the repeatedly utilization of blade, save consumptive material. the utility model is controlled arc test by robotization, can reduce the danger in when test, accurate Control experiment process again, raising success of the test rate, can also increase the term of life of blade, reduce consumptive material.
