Abstract

The passive low-pressure apparatus for reducing adversely elevated temperatures or for suppression of flaming in protected electrical devices according to the present invention is accommodated inside the protected electrical device and consists of carrying body (1) inside which there is some compressed cooling medium (3), wherein said carrying body (1) is also equipped with a charging valve (5) through which the cooling medium (3) is injected into the carrying body (1). Furthermore, there is a pressure gauge (2) for indicative passive control of the cooling medium inside the carrying body (1) and a pressure sensor (4) responsible for disconnecting the protected device from the power supply and connecting it to alarm equipment. Said carrying body (1) is an enclosed hollow compartment of any shape and size made of a plastic, metal or metal alloy, wherein the carrying body (1) is provided with at least one temperature detector, such as a thermal glass vial (6), which breaks inside the protected device when the temperature reaches elevated levels, whereupon the carrying body (1) is ruptured and the medium (3) spills inside the space of the protected electrical device and cools the adversely elevated temperature or suppresses any flaming in said protected electrical device. The thermal glass vial (6) can be attached to the carrying body by several mechanical methods, for example it can be screwed, glued, soldered and so forth. The activation of the apparatus, i.e. the breaking of the glass vial (6) due to the adversely elevated temperature and the resulting creation of a hole in the carrying body (1) through which the medium spills inside the protected electrical device, begins at 50 degrees Celsius.

Description

ПАСИВЕН АПАРАТ С НИСКО НАЛЯГАНЕ ЗА ОХЛАЖДАНЕ ПРИ НЕЖЕЛАНО ПОВИШЕНА ТЕМПЕРАТУРА ИЛИ ЗА ПОТИСКАНЕ НА ПЛАМЪЧНО ГОРЕНЕ В ЗАЩИТЕНО ЕЛЕКТРИЧЕСКО УСТРОЙСТВОPASSIVE LOW PRESSURE APPARATUS FOR COOLING AT AN UNDESIRABLE ELEVATED TEMPERATURE OR FOR FLAME SUPPRESSION IN A PROTECTED ELECTRICAL DEVICE

Област на техникатаField of technique

Изобретението се отнася до охлаждане при нежелано повишена температура или потискане на пламъчно горене в защитени електрически устройства, например в климатични и въздухообработващи инсталации, газови връзки, електрически подстанции и табла, в компютърни кутии, в сървъри, телефонни централи и други подобни. В тези защитени електрически устройства могат да възникнат нежелани топлинни явления, чиито отрицателни ефекти могат да доведат до постепенна загуба на функционалност или разрушаване на тези устройства, а в екстремни случаи могат дори да доведат до пламъчно горене. Това може да бъде причинено от различни процеси, като например нежелани химични реакции, електрически къси съединения, прегряване на системата, електрическа дъга, възпламеняване на работни флуиди и др.The invention relates to cooling in case of undesired elevated temperature or suppression of flame combustion in protected electrical devices, for example in air conditioning and air handling installations, gas connections, electrical substations and switchboards, in computer cases, in servers, telephone exchanges and the like. Undesirable thermal phenomena can occur in these protected electrical devices, the negative effects of which can lead to the gradual loss of functionality or destruction of these devices, and in extreme cases can even lead to flaming combustion. This can be caused by various processes, such as unwanted chemical reactions, electrical short circuits, overheating of the system, electric arcing, ignition of working fluids, etc.

Предшестващо състояние на техникатаPrior art

За да се намали нежеланото повишаване на температурата, или за да се потисне пламъчното горене в защитени електрически устройства, е подходящо използването на апарати с ниско налягане. Съществуват автоматични апарати с ниско налягане за охлаждане на нежелано повишената температура или потискане на пламъчното горене в защитени устройства, които включват носач на охлаждаща среда, чието активиране се основава на счупване на носача на охлаждащата среда, поради нежелано повишената температура или възникналото пламъчно горене в защитеното устройство. За тези устройства температурата, при която носачът на охлаждащата среда се счупва, не може лесно да се контролира, за да се предотврати разливането на средата вътре в защитеното устройство.To reduce unwanted temperature rise, or to suppress flame combustion in protected electrical devices, the use of low-pressure apparatus is appropriate. There are automatic low-pressure devices for cooling the undesired elevated temperature or suppression of flame combustion in protected devices, which include a carrier of cooling medium, the activation of which is based on the breakage of the carrier of the cooling medium, due to the undesired increased temperature or the occurrence of flame combustion in the protected device. For these devices, the temperature at which the coolant carrier breaks cannot be easily controlled to prevent the media from spilling inside the protected device.

Техническа същностTechnical essence

Горепосоченият недостатък се елиминира и областта на защитното оборудване се допълва от апарат с ниско налягане за намаляване на нежелано повишената температурата или за потискане на пламъчното горене в защитено електрическо устройство, който е разположен в това защитено електрическо устройство и се състои от носач, вътре в който има компресирана охлаждаща среда; носачът е допълнително снабден с вентил за пълнене за пълнене на охлаждащата среда вътре в носача; освен това, носачът е снабден с манометър за пасивен ориентировъчен контрол на охлаждащата среда и сензор за налягане за изключване на защитеното електрическо устройство от електрическото захранване и за свързване със сигнално оборудване, в случай че се открие нежелано повишаване на температурата вътре в защитеното устройство, при което същността на изобретението е, че носачът е направен от пластмаса, или метал, или метална композиция, във всякаква куха затворена форма и размер, при което носачът е допълнително снабден с поне един температурен детектор, например топлинна стъклена ампула. Топлинната стъклена ампула е прикрепена към носача по няколко метода, например тя е завинтена, залепена, запоена и т.н. към отвора на корпуса на носача. Веднага щом температурата в зоната на защитеното електрическо устройство, където е разположен апаратът с ниско налягане, се повиши до определена нежелана стойност, стъклената ампула се счупва, създава отвор в носача, през който охлаждащата среда се разлива в пространството на защитеното електрическо устройство и охлажда нежелано повишената температура или потиска пламъчното горене.The above-mentioned drawback is eliminated and the field of protective equipment is supplemented by a low-pressure apparatus for reducing the undesirably increased temperature or for suppressing flame combustion in a protected electrical device, which is located in this protected electrical device and consists of a carrier inside which has a compressed cooling medium; the carrier is additionally equipped with a filling valve for filling the cooling medium inside the carrier; in addition, the carrier is equipped with a pressure gauge for passive indicative control of the cooling medium and a pressure sensor for disconnecting the protected electrical device from the electrical supply and for connecting to signaling equipment in the event that an unwanted increase in temperature is detected inside the protected device, at which the essence of the invention is that the carrier is made of plastic, or metal, or metal composition, in any hollow closed shape and size, wherein the carrier is additionally provided with at least one temperature detector, for example a thermal glass ampoule. The thermal glass ampoule is attached to the carrier by several methods, for example, it is screwed, glued, soldered, etc. to the carrier housing opening. As soon as the temperature in the area of the protected electrical device, where the low-pressure apparatus is located, rises to a certain undesirable value, the glass ampoule breaks, creates an opening in the carrier, through which the cooling medium spills into the space of the protected electrical device and cools undesirably elevated temperature or suppresses flame combustion.

Носачът на охлаждащата среда е снабден с уплътнителна връзка за някои видове оборудване.The coolant carrier is equipped with a sealing connection for some types of equipment.

Температурата на активиране на апарата, когато топлинната стъклена ампула се счупи, вследствие на нежелано повишената температура, създавайки отвор в носача, през който охлаждащата среда се разлива вътре в защитеното електрическо устройство, е 50 °C. Стъклените ампули са изработени от стъкло с различен състав, което се счупва при различни температури в диапазона от 50°С до 260°С.The activation temperature of the apparatus, when the thermal glass ampoule breaks due to the undesired increased temperature, creating an opening in the carrier through which the cooling medium spills inside the protected electrical device, is 50 °C. Glass ampoules are made of glass with different composition, which breaks at different temperatures in the range from 50°C to 260°C.

Температурата, при която топлинната стъклена ампула се счупва, може да се настрои чрез използване на ампули, имащи различни състави на стъклото и по този начин активирането на апарата с ниско налягане може да се контролира, в съответствие е условията и предположенията за появата на нежелано повишената температура.The temperature at which the thermal glass ampoule breaks can be adjusted by using ampoules having different glass compositions and thus the activation of the low-pressure apparatus can be controlled, according to the conditions and assumptions for the occurrence of the undesirably elevated temperature.

Пример 1Example 1

Пасивният апарат с ниско налягане за намаляване на нежелано повишена температура или потискане на пламъчно горене в защитените електрически устройства, показан на фиг. 1, е създаден за разполагане вътре в защитено електрическо устройство, като например една по-малка електрическа подстанция, при което апаратът се състои от носач 1, изработен от метал във формата на кух паралелепипед, затворен чрез заваряване, при което носачът 1 е допълнително снабден с вентил за пълнене 5 за пълнене на охлаждащата среда 3 вътре в носача 1, в който охлаждащата среда 3 е под налягане, носачът 1 освен това е снабден с манометър 2 за пасивен ориентировъчен контрол на състоянието на охлаждащата среда 3 в носача 1. Носачът 1 е допълнително снабден с топлинна стъклена ампула 6, която има резба от едната страна и е завинтена в корпуса на носача 1, където е направен отвор с резба, така че отворът да е запечатан. Ако в защитеното електрическо устройство, тук в това примерно изпълнение за по-малка електрическа подстанция, температурата се повиши до нежеланата стойност от 50 °C, стъклената ампула 6 се счупва и по този начин поврежда носача 1, в който се образува отвор и охлаждащата среда 3 се разлива вътре в пространството на защитеното електрическо устройство, т.е. вътре в пространството на по-малката електрическа подстанция и охлажда нежелано повишената температура в това защитено устройство. По този начин пасивният апарат с ниско налягане се активира, а температурата на активиране в това примерно изпълнение е 50°С. Топлинната стъклена ампула 6 е направена от стъкло, което се счупва при температура от 50°С. Освен това, апаратът за намаляване на повишената температура или евентуално потискане на пламъчното горене в едно защитено електрическо устройство е снабден със сензор за налягане 4 за изключване на защитеното електрическо устройство от източника на електрическа енергия и за свързване със сигналното устройство, ако се достигне зададената нежелана температура в защитеното електрическо устройство.The passive low-pressure apparatus for reducing unwanted elevated temperature or suppressing flame combustion in protected electrical devices, shown in Fig. 1, is designed to be placed inside a protected electrical device, such as a smaller electrical substation, in which the apparatus consists of a carrier 1 made of metal in the form of a hollow parallelepiped, closed by welding, in which the carrier 1 is additionally equipped with a filling valve 5 for filling the cooling medium 3 inside the carrier 1, in which the cooling medium 3 is under pressure, the carrier 1 is also provided with a pressure gauge 2 for passive indicative control of the state of the cooling medium 3 in the carrier 1. The carrier 1 is additionally provided with a thermal glass ampoule 6, which is threaded on one side and is screwed into the carrier body 1, where a threaded hole is made so that the hole is sealed. If in the protected electrical device, here in this exemplary embodiment for a smaller electrical substation, the temperature rises to the undesirable value of 50 °C, the glass ampoule 6 breaks and thus damages the carrier 1, in which a hole is formed and the cooling medium 3 is spilled inside the space of the protected electrical device, i.e. inside the space of the smaller electrical substation and cools the unwanted increased temperature in this protected device. Thus, the low pressure passive apparatus is activated, and the activation temperature in this exemplary embodiment is 50°C. The thermal glass ampoule 6 is made of glass that breaks at a temperature of 50°C. In addition, the apparatus for reducing the elevated temperature or possibly suppressing the flame combustion in a protected electrical device is provided with a pressure sensor 4 for disconnecting the protected electrical device from the source of electrical energy and for connecting to the signaling device if the set undesirable is reached temperature in the protected electrical device.
