Description

Intelligent substation outdoor intelligent case heat sink

Technical field

The utility model relates to a kind of heat sink, particularly relates to a kind of heat sink of lowering the temperature to intelligent substation intelligent terminal box (hereinafter referred to as intelligent box).

Background technology

Intelligent substation adopts intelligent equipment that is advanced, reliable, integrated and environmental protection; basic demand is standardized as with information digitalization, communications platform networking, information sharing; automatically complete the functions such as information gathering, measurement, control, protection, metering and detection, and possess the transformer station supporting the Premium Features such as electrical network control automatically in real time, Intelligent adjustment, on-line analysis decision-making and collaborative interaction.And outside transformer substation intelligent box to be the electric parameters transmitted instrument transformer carry out merging and synchronous process, and the digital signal after process is transmitted to the device of bay level equipment according to specific format.As can be seen here, outside transformer substation intelligent box is the important component part that intelligent substation realizes power transformation Based Intelligent Control.It is arranged on primary equipment place, and inside is provided with interface circuit, photoelectric switching circuit, data processing and transmission circuit and power supply etc., and in case, plate is concentrated, and electronic device requires higher to the temperature of case environment, humidity, cleannes.Its entirety is made up of outer case, internal box and intelligent terminal printed substrate electronic device machine basket, because described intelligent box electronic device is placed in internal box, its electronic device produces certain heat in During Process of Long-term Operation, add global warming in recent years, summer weather is hot, reaching as high as 38-40 DEG C, is exposed to the sun in the sun and can reaches 70-80 DEG C in casing outside.Radiating condition own is poor again, certainly will cause the further rising of intelligent substation case temperature or serious overtemperature.Intelligent substation case was in operation and ran into described overtemperatute in the past, have to open chamber door aeration-cooling, but easily fall in the process dust, insect and toy enter in case, very easily intensive electronic circuit is constituted a threat to and initiating failure, substation equipment accident may be caused even to cause power grid accident.Very easily cause burning and puncturing of electronic device, directly affect intelligent substation all-around intelligent and control.At present, domestic effective temperature-reducing measure is not all taked to intelligent substation outdoor intelligent case, great potential safety hazard certainly will be brought to the normal power transmission and transformation of the safe and reliable operation of intelligent box and transformer substation system.

Summary of the invention

The purpose of this utility model is to provide a kind of good cooling effect, takes into account dust-proof, moistureproof intelligent substation outdoor intelligent case heat sink simultaneously.It can ensure that electronic device is to the temperature of case environment, humidity and cleannes requirement, reliably eliminates its potential safety hazard.The defect that prior art is existed is made up.

Technical solutions of the utility model are as described below: form high-pressure air feed main body by air compressor machine, air accumulator, decontaminating separator being linked in sequence through unidirectional valve and pipeline, the export pipeline of described high-pressure air feed main body is established the multiple air feed branches be in series by electromagnetically operated valve and vortex tube supersonic generator, and at the inner set temperature automatic controller of intelligent box, the open and close controlling described electromagnetically operated valve by described Automatic Temperature Control output realize.

The beneficial effects of the utility model: owing to taking the high-pressure air feed main body of air compressor machine, air accumulator and decontaminating separator composition, add organic cooperation of solenoid, vortex tube supersonic generator and Automatic Temperature Control, reliably can realize the temperature automatic control to intelligent box, be reached for the object of its cooling.Obviously eliminate safe hidden trouble.The air of clean dried owing to entering in intelligent box, avoid the harm that heated term humid air causes electronic device in case, simultaneously, due to compressed-air actuated introducing, make to be in barotropic state in case, it also avoid extraneous humid air or dust enters in case, more ensure that drying in intelligent box is with clean.And have inventive concept novelty, simple and practical, operation maintenance convenient, realize automatically controlling, cooling-down effect is obvious, stable and reliable for performance, be applicable to carrying out the advantage such as promoting.

Accompanying drawing explanation

Fig. 1 is intelligent substation outdoor intelligent case heat sink overall structure schematic diagram.

Embodiment

Intelligent substation outdoor intelligent case heat sink shown in Fig. 1 is by arranging air compressor machine 1, air accumulator 2, decontaminating separator 3, meanwhile, they is carried out connecting to form a high-pressure air feed main body according to described order through unidirectional valve 4,41,42 and connecting line.High-pressure air feed body exit pipeline 5 end unidirectional valve 43 is arranged for closing pipe line.Described high-pressure air feed body exit pipeline 5 is established respectively and to be in series the multiple air feed branches formed by electromagnetically operated valve 6 and vortex tube supersonic generator 7, the quantity of described air feed branch should be corresponding with the number of intelligent box 8.Meanwhile, at the inside set temperature automatic controller 9 of controlled intelligent box 8, then export control signal to control the automatic open and close of described electromagnetically operated valve 6 by described Automatic Temperature Control 9.

During the work of this device, first open other unidirectional valve 4,41,42 except unidirectional valve 43 and connect the working power of Automatic Temperature Control 9, pressure-air is produced by air compressor machine 1, air accumulator 2 stores, after the purified treatment (mainly dehumidifying, dedusting) of decontaminating separator 3, dry, clean pressure-air is sent into high-pressure air feed body exit pipeline 5.Pipeline again through air feed branch accesses the vortex tube supersonic generator 7 being arranged on intelligent box 8, when being entered nozzle of vortex tube by the gases at high pressure compressed, expanding and accelerate in nozzle, forms free vortex flow.Because angular speed is different, just friction is created between layers in free vortex flow, there is energy transferring, two ends obtain hot and cold different air-flow respectively, at this moment the cryogenic gas produced by supersonic generator 7 is sent in intelligent box 8 lowers the temperature to it, hot-air is then discharged to outside intelligent box 8, the working power of the electromagnetically operated valve 6 that the temperature inside the box is controlled on branch's supply air line according to design temperature by the automatic temperature controller 9 be arranged in case opens and closes automatically, and then the automatic control realized intelligent box 8 temperature, reach the object of cooling.Moreover, the air of clean dried owing to entering in case, avoid the harm that heated term humid air causes electronic device in case, simultaneously, due to compressed-air actuated introducing, make to be in barotropic state in case, avoid extraneous humid air or dust enters in case, ensure that drying in case is with clean.Thus further obviate fail-safe hidden danger, the normal operation of the safe and reliable operation of intelligent box 8, transformer substation system and even electrical network is ensured conscientiously.
