Owing to be provided with said structure; this device can prevent to open by mistake the generation of 10kV electrification in high voltage cabinet accident; can remind switch cubicle whether charged; watchdog device converts the high-tension electricity of " invisible " to the alarm sound of " tangible "; effective prevention work personnel mistakenly entering charged chamber; for power worker's life security provides a reliable protection net, satisfied the requirement of power grid security, reliable, stable operation.
Description of drawings
Fig. 1 is the circuit theory diagrams of a kind of high-tension switch cabinet of the present utility model " house dog " device.
Embodiment
As shown in Figure 1, a kind of high-tension switch cabinet " house dog " device is made of charged induction installation, warning device, infrared signal sniffer, and described charged induction installation links to each other with warning device 35 respectively with the infrared signal sniffer.Described charged induction installation is made of spherical metal A phase sensor 11, spherical metal B phase sensor 12, spherical metal C phase sensor 13, power supply input 14, charged treating apparatus 15, described spherical metal A phase sensor 11, spherical metal B phase sensor 12, spherical metal C phase sensor 13 are connected with charged treating apparatus 15 respectively, and described charged induction installation 15 connects pilot lamp 16.Described charged treating apparatus 15 is made of relay, and during the charged action of solenoid, contact is communicated with.Described spherical metal A phase sensor 11, spherical metal B phase sensor 12, spherical metal C phase sensor 13 are installed on the dead ahead of electrified body, apart from being separated by 125+25 mm.Described infrared signal sniffer is formed by connecting by infrared transmitter 31, sensor 32, infrared signal processor 33 successively, described infrared signal processor 33 is connected with power supply 34, described infrared signal processor 33 links to each other with warning device 35, described infrared transmitter 31 is a Fresnel Lenses, and described sensor 32 is a pyroelectric sensor.Described warning device 35 is made of hummer and flashlamp.During installation, sensor metal inductive probe three-phase is installed on the dead ahead of electrified body and the electrified body distance 125+25 mm of being separated by respectively, the base terminal screw can not bump with metal shell and connect during installation, in order to prevent to open by mistake the generation of 10kV electrification in high voltage cabinet accident, can metal sensor be installed outward at switch cubicle inner cable head safe distance, and be connected with electrification display, utilize the three-phase pilot lamp on the display to remind this switch cubicle whether charged.Install the charged alarm device of infrared ray simultaneously additional at the rear cabinet door top, the induction range that relies on infrared ray to form gets up switch cubicle " protection ".When the approaching charged interval of work about electric power personnel rear cabinet door, the infrared protection device can in time send alerting signal, reminds and has been strayed into the danger zone, should enhance your vigilance; If off interval does not then send alerting signal.Charged display process circuit is installed on the high-tension switch cabinet door, highly overhead is advisable to estimate the position that can observe pilot lamp.During use, when tested 10kV equipment had high-tension electricity, sensor imported in display+induced voltage about 5V, and corresponding A, B, C pilot lamp are bright.When in the three-phase any one when mutually induced voltage being arranged, the display interior relay all can move, its junction closure, provide signal power source to infra-red detection alarm instrument, it mainly is to catch light and be reflected on the pyroelectric sensor by Fresnel Lenses that heat is released infrared inductor, sensor converts digital data transmission to by integrated circuit and whether sends warning to the backstage for the central processing unit decision then, instrument does not comprise independently host scm but directly adopts this integrated circuit of BISS0001, can utilize its directly to drive the flash of light of reporting to the police and save cost.Instrument has comprised flash of light and alarm buzzer simultaneously, and any object of occurring in nature all can produce infrared spectrum, and the infrared energy wavelength that the temperature difference is discharged also is not quite similar.The wavelength of human body is about 10 μ m, and whether therefore can judge according to this is that human body is near device.And Fresnel Lenses to be the thin skin that has polyene footpath material to make also have some is that glass is made, its significant feature is as focusing on, and is about to heat and releases the infrared signal refraction or reflex on the PIR.Second effect is that detecting area is divided into light and shade two districts, makes the mobile object that enters the zone produce heat with the form of temperature variation on PIR and releases infrared signal.Cost and stability at this instrument consider that we determine to adopt this infrared signal processor than high performance-price ratio of BISS0001, mix the rpyroelectric infrared alarm contact that in type Fresnel Lenses and part outward element are made into a passive type again.Supporting pyroelectric sensor is RE200B.And Fresnel Lenses adopts the polyene footpath eyeglass of 360 degree, about 8 meters of its detection range, focal length is 10.5 millimeters, characteristic according to sniffer, on follow-up expanded function, can add communication module, as install the gsm module additional, prerequisite is to add cpu rather than simply utilize BISS0001, so just the time of reporting to the police can be transmitted back, and the software kit database can be inquired about, the situation that monitors warning that so just can remote live is highly significant for the construction of intelligent transformer station.
