Description
Technical field
The utility model relates to field of mechanical technique, is specifically related to a kind of apparatus overheat alarm.
Background technology
During running use, often there is the phenomenon that heating causes temperature anomaly to raise in equipment.The temperature change of detection equipment privileged site is the feasible method whether discovering device exists potential faults, and relevant technical scheme also has a lot.But for the electric power overhead conductor coupling portion position overheated monitoring, alarming of fault, the effect that realizes of prior art there is also many weak points.
Operation power unit common practice is the infra red thermograph monitoring in employing cycle now, serves the effect of discovering device overheating defect to a certain extent.But, infra red thermograph exists inconvenient to carry, when making an inspection tour, the detection cost time is more, the factors such as price is high, cause thermal infrared imager detection method simply to use when making an inspection tour especially, and do not use when customary tour so that some heating defects can not find in time, add fault to continue to deteriorate the probability becoming accident, bring risk to operation of power networks.
It is also a solution that connecting portion at conductor installs temperature alarm.
Application number CN201510697429.5 discloses a kind of electrical equipment heating indicator and drives element and preparation method thereof, and indicator includes base, drives element and the upper cover with base engagement；Element is driven to be installed between base and upper cover；Driving element material is marmem；Driving element is around the planar spiral formed when normal temperature, is the three-dimensional spirality longitudinally highly increased by thermal deformation rear drive element.It is little that the utility model has volume, sensitive feature, is particularly suitable for installing and using in the narrow and small device space.But this technical scheme is if applied on transmission line of electricity, then can there is following weak point: 1, transmission line of electricity tower height is typically at tens meters, memory metal area is the least to be difficult to be observed visually by underground track walker in ejection state；2, lacking tight sealing, in the wild wind and weather between base and upper cover, time length, the warning color that surface is coated with easily is faded；3, the measurement tolerance of material is generally at 10 ° of more than C, not high enough to the accuracy of measurement of temperature.
Application number CN201510018197.6 discloses power system high-low pressure heating position automatic indicator, with TiNi two-way memory alloy intelligence spring temperature-sensing element, the ejection making TiNi two-way memory alloy intelligence spring generation mechanical movement control red flag by the temperature on the contact that TiNi two-way memory alloy intelligence spring perception is easily generated heat shows on the contact of easily heating.This technical scheme exists: 1, red flag does not has tight sealing, in the wild wind and weather, time length, and the warning color that surface is coated with easily is faded；2, the measurement tolerance of material is generally at 10 ° of more than C, not high enough to the accuracy of measurement of temperature；3, volume is big, and mechanism is complicated, is applied on ultra-high-tension power transmission line, is susceptible to corona, produces radio interference.
Realize the connecting portion of high pressure electric line is carried out temperature alarm, need to solve following problem: 1, the functional reliability of monitoring device necessarily be greater than the reliability of connecting portion of high pressure electric line, otherwise misoperation is more frequent than equipment heating fault, it is impossible to alleviate operation workload.2, equipment wants sealing corrosion, durable in use, otherwise often to change, and work high above the ground operating expenses is high.3, monitoring device volume is sufficiently small, and profile is round and smooth, is susceptible to corona discharge outside the most too protruding from conductor, produces the radio interference and audible noise exceeded standard.4, temperature once reaches alarm temperature, and alarm indication persistently to keep, it is impossible to when temperature reduces again, and alarm condition disappears, otherwise track walker is relatively low in power line load, wind speed relatively low compared with big, temperature when line walking time can not discovering device fault.5, alarm indication state to arrive more than 300 square millimeters with the shape difference of normal condition, otherwise is difficult to find tens meters of high alarm indications when coming back viewing.6, instruction material of reporting to the police should use insulating materials, otherwise when instruction material of reporting to the police stretches out, is susceptible to corona discharge, produces the radio interference and audible noise exceeded standard outside too protruding from conductor.7, connection is installed and wants reliable, be otherwise arranged under the intense vibration of wire and be susceptible to get loose.8, monitored equipment is close at the temperature-sensitive position of monitoring device, and otherwise under the strong wind state of high-altitude, temperature-sensitive position and monitored equipment excessive temperature differentials, the degree of accuracy declines.
Summary of the invention
The utility model purpose is to provide a kind of apparatus overheat alarm, is used for solving electric power overhead conductor coupling portion position fault overheated monitoring, alarming problem, and realizes further: 1, reliable operation, alleviates operation workload；2, sealing corrosion is durable in use.3, low-profile is round and smooth, is difficult to corona discharge；4, alarm condition can keep；5, instruction of reporting to the police easily is found；6, simple installation, firmly；7, accuracy of detection is high.
To achieve these goals, the utility model provides a kind of apparatus overheat alarm, it is characterized in that an instruction cloth folds and puts into a bottle together with after a spring-compressed, cover a bottle cap, bottle cap is connected with flipe one end, bottleneck and the joining place low-melting alloy welded seal of bottle cap, bottle cap surface snugly fits to monitored equipment surface, when monitored equipment temperature is higher than low-melting alloy fusing point, low-melting alloy melts, flipe is ejected bottle by compression spring and launches, and it is overheated that display alarm equipment there occurs.
Above-mentioned low-melting alloy, it is characterised in that its fusing point selection range is 50 to 200 degrees Celsius.
