Description
Technical field
The present invention relates to a kind of triode and puncture proving installation, particularly a kind of triode oscillation device based on relay.
Background technology
The test philosophy that existing triode punctures test is all to disconnect in base stage, and rated current in addition between emitter and collector, then tests the voltage breakdown between emitter and collector.According to desirable test, should be triode base stage what do not connect, completely unsettled, but in fact, in process of production because same test station need to be tested other parameter simultaneously, when in industry, conventional way is all test triode voltage breakdown at present, in inside, testing station, the connecting line of base stage is disconnected, as shown in Figure 1, because testing station is from the have an appointment connecting line of 1 meter of the base stage of triode, if external interference is larger, the base stage of triode own is more responsive again, also or the base stage of triode not completely disconnect, can be to test generation oscillatory occurences.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of triode oscillation device based on relay is provided, in the time puncturing test, K switch 309 open circuits that are connected with base stage make base stage unsettled, reduce the interference of introducing from base stage, effectively improve triode and puncture the Stability and veracity of test.
The object of the invention is to be achieved through the following technical solutions: a kind of triode oscillation device based on relay, it comprises current load unit, puncture test cell and biasing circuit unit, current load unit comprises power supply, puncture test cell and comprise voltage table V, K switch 309 and place the triode test bench of triode when testing, biasing circuit unit comprises variable resistor, described triode test bench is provided with collector terminals C, base terminal B and emitter terminals E, the collector terminals C of triode test bench is connected with the positive pole of power supply, the base terminal B of triode test bench is successively by K switch 309, K switch 209 is connected with the negative pole of power supply, the emitter terminals E of triode test bench is successively by K switch 112, ground connection after K switch 3 and variable resistor, the collector terminals C of triode test bench is also successively by K switch 8, ground connection after K switch 7 and voltage table, described K switch 309 is relay switch.
