Description
Technical field
The utility model relates to the test unit of low voltage switch equipment and opertaing device, specifically belongs to the field tests of Switch electric equipment products operating physical force.
Background technology
Electric equipment products have conflict all the time in the safety of restriction product and reliably and with long-term use in the process of design, manufacturing.Should make operating physical force suitable, can resist enough durability tests again doing quick switching of time spent, to guarantee the firm and durable of product.The safe break-make of electric equipment products and serviceable life are the factors that enterprise must consider in design, transformation process always.
International Electrotechnical Commission's basis is multinational actual usage data a large amount of " closing-oco " aspect low voltage switch equipment and the opertaing device in the world, set up standardized mathematical model, having summed up out the safe break-make that can guarantee these type of electric equipment products in Great possibility uses, the rule that arranged certain serviceable life again, formed IEC60947-1 " Low-voltage switchgear and controlgear Part1:General rules ", performance to these type of electric equipment products, index, require to wait the regulation of having done quantification, become the common standard of carrying out of each member state, with the design of standard various countries to this electric appliances, test and use.
According to this existing IEC60947-1fifth edition2007-06 standard, various countries relevant unit is to carry out 8.2.5.2Method of test in the test method of operating physical force F and limit operation power 3F, concrete data are to carry out Table17-Actuator test force, and test method is to carry out Figure16-Actuator test force.
Various countries relevant unit is doing a large amount of effort aspect the measuring mechanical property of these all kinds of electric equipment products, derived testing apparatus and the test regulation that all meets corresponding standard-required from principle, structure, operation etc. according to different relevant criterion contents.As: China invention 01141653.X/ international monopoly: (Japan) 92102476.2/ international monopoly: (Britain) 95194152.6/ international monopoly: (Germany) 200680011468.4/ international monopoly: (U.S.) 94192779.2 etc., respectively the novel method such as " closing-the oco "/force-measuring sensing of electric test/dynamometry electromagnetic conversion/absorption dynamometry and technology have been done well openly, had great reference value.But, not yet see the patent article of relatively properer this individual event F, 3F device for measuring force or the open and description of scientific and technological class report.
Existing in the industry more commonly with the guidance of this standard as principle, various countries' applying unit substantially all is to carry out F, 3F dynamometry with thrust meter.Concrete mode is according to shown in Fig. 6 (Figure16-Actuetor test force), with the coincide end straight line of test product operating grip of the push rod head center-diameter line of thrust meter, the push rod axis becomes plumbness with the straight line plane, end of operating grip, holding thrust meter slowly exerts all one's strength, remain simultaneously intrinsic plumbness, until measure F power; After the moving contact locking of stipulating subsequently, row carries out the measurement of 3F power with above-mentioned method again.
As standard compliant this method of testing of relatively being accustomed in the industry, still there is flaw to exist.For smaller test product and non-smooth for the operating grip end, or even the test product of circular arc type (including sheath), measure according to above-mentioned conventional process in the process of F power, because the shape of test product makes the situation variation of force position, the slippage situation can appear in application of force process, cause the less than normal and laboratory technician of test figure therefore " slippage phenomenon " the injured possibility that leans forward is arranged.Existing solution is additionally to make an overcoat of reasonably eliminating irregular at operating grip, to guarantee still can to carry out correct measurement according to said method.
Owing to be to form dynamometer push rod axis when relying on manpower to guarantee to measure to become plumbness with the straight line plane, end of operating grip, and in the motion process of measuring, operating grip after stressed is that rotate in axle center intrinsic in test product, when this moment, the dynamometer push rod was forced in the application of force, also must in test product, rotate in intrinsic axle center, constant with the direction of confining force.In the case, dynamometry is in respect of a plurality of random motion degree of freedom, and the push rod axis can not become plumbness with the straight line plane, end of operating grip, a component of pressing to test product can occur, and the dynamometry reading of guide rule reality is for making a concerted effort, and is slightly larger than real dynamometry.
For the comprehensive measuring station of specialty, not only want complete operative norm, the process of the operative norm of keeping under strict control especially, at all error to some extent.In the real IEC60947-1 standard of carrying out, carry out just needing a kind of brand-new device badly in F, the 3F dynamometer check, get rid of the direct effect of staff, advance to be raised to plant equipment and eliminate uncertain factor, the assurance process is reasonable, data are accurate, characterize the detectability consistent with standard-required.
