Description
Technical field
The present invention relates to a kind of substation primary equipment safety inspection method for monitoring, belong to the power technology field.
Background technology
The more common alarming in short range of electric power device of State Grid Corporation of China mainly is that watch style alarming in short range of electric power device and safety helmet install the alarming in short range of electric power device additional at present, the shortcoming of this kind warning device is that nearly electro-induction is reported to the police not to direct current, high frequency and static early warning, and function singleness is only limited to alarming in short range of electric power, does not have the speed warning function during near primary equipment for vehicle and personnel.The characteristics that warning from now on possesses are characteristics flexible, reliable, multi-functional and that cost is low.Delivery electric-examination is in the past repaiied operation and is all adopted screening clothing, utilizes overhead insulation bucket arm vehicle or earth potential indirect operating.According to site environment, the electrical equipment structural condition of the determined safe distance of rules and distribution hot line job, as can be seen in the electric hot line job of providing and delivering, should be based on indirect operating in order to ensure safety.Now, along with the development of domestic and international hot line job technology, every performance and the index of insulation clothing have a continued development, and the insulating protection instrument is also more reliable, light.Particularly external insulating tool product more is better than home products, and constituent parts all uses external insulation clothing and insulating protection apparatus basically.
Current domestic charged operating distance is reported to the police and is comprised that watch style alarming in short range of electric power device and safety helmet install the alarming in short range of electric power device additional, also has the infrared correlation alarm of less use and the safety alarm device of complicated hot line job power construction.
At present domestic charged operating distance is reported to the police and is comprised that watch style alarming in short range of electric power device and safety helmet install the alarming in short range of electric power device additional, also has the infrared correlation alarm of less use and the safety alarm device of complicated hot line job power construction.The former function is only limited to alarming in short range of electric power, but closely electro-induction is reported to the police not to direct current, high frequency and static early warning, and the latter's cost and technical requirement are higher.For example going up the Radio infrared alarm that the prompt science and technology in marine site is produced, is to belong to infrared correlation alarm, and the characteristics of this equipment are to need to install injection device and microcomputerized control, are mainly used in burglar alarm at present.Also have Nanjing to consult soft Information Technology Co., Ltd and cooperate with state household electrical appliances industry department, researched and developed novel high-pressure power equipment protection against electric shock early warning system.The shortcoming of this system is exactly higher to the cost of the hardware device of monitor signal leading portion analyzing and processing.
The professional image analysis system that the measuring distance function is abroad arranged, for example Image-Pro Plus is top image analysis system bag, it has comprised unusual abundant survey instrument.Also have velocity measuring system RC Speed Test can run in the ios system.But two kinds of systemic-functions of charged execute-in-place are single, can not effectively prevent the generation of operating personnel's mistakenly entering charged chamber and personnel's electric shock accidents.At present on the market at the Android mobile phone development the similar intelligent distance-measuring Smart Distance Pro v2.1.6 of system, the function of this system is according to the distance between input object height measurement operator and the object, and utilizes video clips to measure movement velocity.Also have Smart Measure system, when the contact point that takes target object and ground and object peak, just can calculate the target object height.Characteristics such as these two kinds of systems belong to tool system, and committed memory is few, and is simple to operate, flexible.
Generally speaking, no matter be the domestic or external multifunction system that does not also have charged distance alarm and velocity test.Carry the special-purpose alarming in short range of electric power device of guaranteeing safe operation or have only single nearly electrical measurement to operate the current safety inspection of incompatibility apart from the hardware of function.We are in conjunction with prior art and s own situation, and the proposition of innovation primary equipment maintenance safety method for monitoring.
