Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of easy for installation, fail safe good, data transmission security is stable device for fast disconnecting high voltage testing source is provided.
The objective of the invention is to accomplish through following technical scheme; Described device for fast disconnecting high voltage testing source; It includes experiment power supply control device and four infrared ray fences; Described four infrared ray fences are square and are arranged in around the high-tension apparatus, and described four infrared ray fences are positioned on the same horizontal plane and through wireless signal and connect mutually, and four infrared ray fences are through wireless signal or wired connection experiment power supply control device.
Described experiment power supply control device includes the input supply hub that is fitted on the shell and switch, out-put supply jack and indicator light, four parts such as infrared alarm indicator light, reset key, earth jack, reception and emission key.
Dispose battery in the described infrared ray fence; Its upper end is equipped with alarm, a lower end and is fixed with tripod; Main body is provided with two far infrared transceiver and forms the first projection fence and the second projection fence; The first projection fence comprises two infrared tubes, and the second projection fence comprises the second fence grenade instrumentation and the second fence receiving system.
Be shaped on mounting and positioning device on the described infrared ray fence.
Far infrared transceiver on the described infrared ray fence is fixed with magnet.
The present invention introduces device for fast disconnecting high voltage testing source with infrared transceiver device, has improved accuracy, when the staff is strayed into the trial zone owing to the pause of certain link produces brain moment vacuum in experimentation; Perhaps the inoperative personnel know perfectly well under the situation of doing experiment when crossing over warning line for the figure that saves time is convenient, can trigger the infrared ray fence, and this moment, the alarm lamp of device for fast disconnecting high voltage testing source lighted; Trigger the voice-control alarm device simultaneously; The firing test power control is cut off the electricity supply, in order to guarantee personal security and device security; This device for fast disconnecting high voltage testing source can also be according to the environment at scene; Suitable sensitivity is set, reduces wrong report, wireless more safe and reliable with the cable data transmission.
