Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, be described below in it is for the present invention
Attached drawing is only some embodiments of the present invention, for those of ordinary skill in the art, what is do not made the creative labor
Under the premise of, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the floor map of blast switch test equipment of the invention in one embodiment.
Specific embodiment
Hereinafter, the present invention will be described in detail with reference to various embodiments shown in the accompanying drawings.But these embodiments are not
The limitation present invention, structure that those skilled in the art are made according to these embodiments, method or change functionally
It changes and is included within the scope of protection of the present invention.
A specific embodiment of blast switch test equipment of the invention shown in referring to Fig.1.The equipment 1 includes a machine
Shell 10, the air duct 11 being connected between blower 20 and blast switch to be measured 70, is arranged in machine the blower 20 being arranged in casing 10
Solenoid valve 30, controller 40 and the current module 50 being arranged in casing 10 in shell and in air duct 11.
Air duct 11 is used to define the access that blower 20 exports wind, and one end connect with blower delivery outlet, the other end then with wind
Compress switch 70 negative-pressure detection port 71 connect.The solenoid valve 30 being arranged in air duct 11 is switched on or switched off by closing or opening
Wind path, thus the opening and closing of simulates blower fan.
Current module 50 is electrically connected with blast switch 70 by conducting wire 12.When the microswitch in blast switch 70 (not
Diagram) be triggered after, have electric signal generation in conducting wire 12, so as to be detected by current module 50.In a specific embodiment
In, current module 50 includes a current monitoring switch 51, which is in normally off.Do not have when in conducting wire 12
When electric signal, current monitoring switch 51 is disconnected, and the microswitch in blast switch 70 is triggered and makes have electricity in conducting wire 12
It is out-of-date to circulate, and current monitoring switch 51 is closed.
Current module 50 is also used to selectively export different size of electric current.In a specific embodiment, the electricity
Flow module 50 includes resistor assembly 52, which contains at least two the resistance with different resistance values, thus current module
Resistance access circuit with different resistance values is exported different size of electric current by selecting by 50.
Controller 40 and blower 20 and solenoid valve 30 are electrically connected with the opening and closing for controlling blower and solenoid valve.
Controller 40 is also electrically connected come for controlling current module output electric current and monitoring the electricity by conducting wire 12 with current module 50
Signal.
The equipment 1 further includes the control panel 60 being arranged on casing 10, which electrically connects with controller 40
It connects to be used to set test parameter, such as test period, testing time.
Preferably, which further includes the insulating box 80 for accommodating blast switch 70 to be measured, and insulating box 80 can be set not
Same temperature carrys out simulated wind pressure switch 70 and works under different temperature condition.
When test, blast switch 70 to be measured is placed in the insulating box 80 for having set temperature, and passes through conducting wire 12 and electricity
Flow module 50 is electrically connected, and negative-pressure detection port 71 is connected to air duct 11.Controller 40 controls blower 20 and opens, and in each survey
Control solenoid valve 30 is connected in the first special time period and is closed in the second special time period in the examination period.For example, electromagnetism
Valve is connected in 10 seconds, is then disconnected in next 5 seconds.So in cycles until reaching scheduled testing time, such as
200000 times.Dduring test, it is not detected once the current monitoring switch 51 of the current module 50 when solenoid valve 30 is connected
There is electric signal in conducting wire 12, then shows that there are failures for blast switch 70 to be measured, i.e., can not pass through life test.Preferably implementing
In mode, when solenoid valve 30 is connected, controller 40 is selected by the resistor assembly 52 in control current module 50 in third
The first specific current value is kept in special time period and keeps the second specific current value in the 4th special time period.For example,
In 10 seconds that solenoid valve 30 is connected, 10 milliamperes are maintained in 300 milliseconds of initial electric currents, and is protected in next 9.7 seconds electric currents
It holds at 300 milliamperes.
The wind power collecting that the test equipment is switched using blower, air duct, solenoid valve come simulated wind pressure, and use current-mode
Block detects the electric signal after blast switch trigger action, a variety of actual operating states that can be switched with simulated wind pressure, thus right
Blast switch carries out reliable life test.
