Abstract
The utility model relates to an electrical equipment detection platform and specifically discloses an automatic breaker test platform used in production lines. The automatic breaker test platform comprises an industrial control computer, a digital acquisition card module, a detection device module, a testing power source module, a bar code scanner and a detection probe. The industrial control computer is respectively connected with the digital acquisition card module, the detection device module and the testing power source module through pci interfaces. The industrial control computer is connected with the bar code scanner through a USB interface. The digital acquisition card module is connected with the detection probe through a cable. The detection device module is composed of a digital i/o card and a detection control device. The detection control device comprises a pneumatic or hydraulic transmission device, a connection sensor, an in-place sensor and a resin plate. The digital i/o card can be connected with the pci interfaces. The testing power source module is composed of a general multi-serial-port communication card and a testing power source. The general multi-serial-port communication card can be also connected with the pci interfaces. The testing power source adopts a linear amplifier structure and a double-transformer double-isolation type design. A signal source then can have the signal noise significantly reduced in a differential mode. By means of system synchronous interfaces, a plurality of data acquisition cards achieve synchronization. The maximum noise reduction is further realized by different gain settings and scanning sequences. Gains and offsets can be adjusted to be within a designated precision range through an automatic calibration function. The resin plate contacting a breaker is an antistatic modified phenolic resin plate and has excellent antistatic functions. The change in the material quality of the probe makes problems characterized by false open circuit, instable resistance, contact failure and electric spark generation solved. The whole test platform thus achieves low noise, no harmonic wave interference and a significant decrease in signal distortion when a small current passes by.
