Embodiment
As illustrated in fig. 1 and 2, a kind of transformer station comprises insulating bar 1, magnet 2, infrared emission assembly 3 and infrared receiving unit 4 with infrared security protection warning device.Described infrared emission assembly 3 is fixed on the insulating bar 1, and described infrared receiving unit 4 is fixed on another root insulating bar 1, and an end of described insulating bar 1 is provided with 5, two blocks of magnet 2 of elongated slot and movably is placed in the described elongated slot 5.Two strong magnets are housed on the every insulating bar, and spacing is adjustable, to adapt to the spacing of different disconnecting link crossbeams.1.1 meters of this insulating bar length overalls, the elongated slot length that is used for adjustment magnet spacing is 16 centimetres, width cooperates with the magnet standing screw, guarantees that it can slide smoothly, fixes with nut at the opposite side of insulating bar.Described device size is not limited to above-mentioned size, need design according to actual needs.
As shown in Figure 3, described infrared emission assembly 3 comprises charhing unit, battery, control module, undervoltage warning unit and infrared palisade transmitting terminal.Described charhing unit is connected with the supply terminals of control module through battery, and the undervoltage warning unit is connected with the output terminal of described control module with the infrared palisade transmitting terminal.As shown in Figure 4, described infrared receiving unit 4 comprises charhing unit, battery, control module, undervoltage warning unit, report to the police time-delay control module, infrared palisade receiving end and alarming horn.Described charhing unit is connected with the supply terminals of control module through battery, described undervoltage warning unit is connected with the output terminal of described control module with described infrared palisade receiving end, and described alarming horn is connected with the output terminal of control module through the time-delay control module of reporting to the police.In order to increase the service time of described device battery, preferred described battery is selected lithium battery for use.
Infrared ray is a kind of invisible light, and can spread, and after throwing away, can form the cone light beam in the initial path stage, and along with the increase of transmitting range, its ideal tensile strength and transmitting range are anti-square of decay.When object is crossed its search coverage, interdict infrared beam and cause alarm.Selecting to consider that every index will satisfy on-the-spot actual needs aspect the infrared warning device.The one, select the suitable triggering response time: the response time is too short to cause unnecessary interference easily, flies over as bird, and falling leaf is crossed and waited the initiation false alarm; Oversize then easily formation failed to report the police.The 2nd, select suitable tolerance, because needs are formed anti-mask by the multi beam infrared ray, thereby form three-dimensional safeguard procedures, and device is mobile model, each installation all needs the infrared emission assembly is aimed at infrared receiving unit, guarantee that every ultrared transmitting and receiving can both aim at, the too small alignment work that will cause of tolerance is very complicated, thereby increases the workload of arranging safety practice; If instead excessive will the causing of tolerance closed on the interference that infrared launcher causes, reduce monitoring effect.The 3rd, consider the power supply matching problem.This device except needs infrared to injection device as also needing control module, alarm unit etc. the topmost original paper, consider the mutual coupling of power supply aspect.The 4th, consider emc issue.This device need be installed in high voltage alive equipment near, so whether can resist the interference of highfield also very crucial.
Described device has used Infrared Alarm Techniques, and it comprises infrared emission assembly and infrared receiving unit, and the scope of protection is selected infrared beam quantity as required.To consider that at the design aspect of the support of infrared emission assembly and infrared receiving unit this device need be applied near the charging equipment, so one be to select insulating material as support, prevent that fortuitous event from causing unnecessary fault.The 2nd, because be portable design, need to consider the selection of fixed form, be convenient to installing and dismounting.The 3rd, consider adaptability, need the position of installing to have some differences in structure and profile, should consider these equipment of adaptation that a kind of support can be as much as possible.The 4th, it is convenient to consider to aim at, and infrared emission end and receiving end need be aligned on the same axis, and support should be able to satisfy aims at the needs of adjusting.
For guaranteeing described device in good condition between the operating period at the scene, in the circuit of infrared emission assembly and infrared receiving unit, designed the undervoltage warning unit, hummer can send chimes of doom when battery is about to exhaust, and reminds the staff in time to charge.This device is applicable to that mainly power transformation specialty part has a power failure and the eminence charging equipment conventional equipment operation field nearer apart from scope of work, especially to 110kV and following equipment better effects if.This device is not suitable for GIS equipment, switch cubicle equipment etc.Two insulating bars can be adsorbed in the two ends of disconnecting link crossbeam during use respectively, the power switch of device for opening, the infrared emission assembly will be launched a branch of infrared light, shine on the infrared receiving unit on opposite.When foreign matters such as ladder, human body blocking-up infrared ray, alarming horn sends strong prompt tone immediately, and prompting is about to the staff in mistakenly entering into charged zone, thereby avoids the generation of personal injury accident.
Used specific case herein principle of the present utility model and embodiment thereof are set forth, the explanation of above embodiment is just with helping understand method of the present utility model and core concept thereof.Should be pointed out that for the person of ordinary skill of the art, can also carry out some improvement and modification to the utility model under the prerequisite that does not break away from the utility model principle, these improvement and modification also fall in the protection domain of the utility model claim.
