Description
Technical field
The utility model relates to electronic measuring technology field, relates in particular to a kind of dash current proving installation.
Background technology
Use in the circuit in reality, especially at power circuit, because power is larger, switch moment input end components and parts will be subject to dash current.ETSI (the EuropeanTelecommunications Standards Institute) stipulates in the mode of steady-state current multiple the Switching Power Supply dash current permissible value that is used for communication system, and wherein maximal value is 90 times in steady operation electric current.This shows, dash current is more much larger than steady operation electric current, and the components and parts that are used for input end need carry out the examination of the ability of withstand shock electric current.
The size of dash current is determined by several factors, such as the input voltage size, inputs the electric wire impedance, power supply inner input inductance and equiva lent impedance, input capacitance equivalence series winding impedance etc.These parameters are different with layout and different according to different power-supply systems, are difficult to estimate, the most accurate method is to measure in actual applications the size of dash current." electronic equipment with fixed condenser part 1 general specification GB/T2693-2001 " although in provided the circuit diagram of dash current test, but being only applicable to single test products tests, and need to manually carry out charge-discharge test, there is the danger of electric shock in not only labor intensive, and operating personnel.
Therefore, instantly need a urgent technical matters that solves to be exactly: how can propose a kind of effective measures, to solve problems of the prior art.
The utility model content
Technical problem to be solved in the utility model provides a kind of dash current proving installation, has effectively realized simultaneously a plurality of components and parts being carried out impact current for measuring and the test of shock-resistant current capacity.
In order to solve the problems of the technologies described above, the utility model provides the dash current proving installation, comprise: direct supply (1), the time relay (2), storage capacitor (3), relay (4) sum counter (5), wherein, direct supply (1) is the working power of relay (4), the time relay (2) is that first order relay (4) is connected direct supply (1), relays at different levels (4) are followed successively by subordinate's relay by intermediate contact and connect direct supply (1), other intermediate contact (6) of each relay connects detected element, by the time relay (2) be set the dash current cycle, counter (5) record also shows the dash current number of times.
Further, described relay (4) is one or more.
Further, described a plurality of relay (4) forms multilevel hierarchy.
