Abstract
A kind of dustless falling temperature technique of controller switching equipment of the present invention, which is utilized, to be removed the partial heat of switch cubicle by collecting, and freezed but using the heat being collected into, make switching station, cell switchgear house, environment temperature reduction in transformer station, at the same avoid switching station, cell switchgear house, in transformer station humid environment, dust etc. influence；The electric elements of switch cubicle are made preferably to work.
Description
Technical field
The present invention relates to a kind of dustless falling temperature technique of controller switching equipment.
Background technology
Switching station, cell switchgear house, widely use enclosed switchgear in transformer station, due to the seal of switch cabinet, over-heat inside phenomenon often occurs, if long-term overheat makes binding post metal change colour, humid environment, radiating condition are poor, the oxidation on cable termination core and binding post surface is accelerated, makes junction contacts bad, localized contact resistance is excessive.Heating accident can cause the insulation thermal breakdown of electrical equipment, thermal deformation, the even melting welding of conductor coupling portion position, seriously jeopardize the safe operation of electrical equipment.At present mainly by gravity-flow ventilation and to heating be monitored.But can not fundamentally eliminate the phenomenon of overheat.
The content of the invention
The present invention is exactly that the invention is not by ambient influnence, the technical problem of dustless, moisture-resistant and temperature stabilization in order to solve to provide a kind of controller switching equipment dustless falling temperature technique for the radiating for being used for electric elements by the oil nature material that insulate.
In order to solve the above technical problems, a kind of technical solution of the dustless falling temperature technique of controller switching equipment of the invention is：
Comprise the following steps：
The first step, the heat transfer that the copper heat exchanger for being fitted in busbar both sides by silica gel produces incoming-line busbar and feeder line busbar is to insulating oil；
Second step, when insulating oil is heated to 60 DEG C, insulating oil is converged by aluminium oxide ceramics pipeline enters switching station, cell switchgear house, the lithium bromide refrigerator outside transformer station, and insulating oil drops to 55 DEG C by 60 DEG C；During this, the chilled water that refrigeration machine cooling offer circulating cooling coolant-temperature gage drops to 16 DEG C, 16 DEG C from 23 DEG C enters switching station, cell switchgear house, transformer station with the air heat-exchange in space, and refrigeration coolant-temperature gage is increased to 23 DEG C.
The heat that incoming-line busbar and the feeder line busbar is produced accounts for the 50% to 60% of whole switch cubicle.
The heat that incoming-line busbar and the feeder line busbar is produced accounts for the 55% of whole switch cubicle.
What the present invention can reach has the technical effect that：The present invention is to utilize the partial heat of switch cubicle to be removed by collecting, and freezed but using the heat being collected into, make switching station, cell switchgear house, environment temperature reduction in transformer station, at the same avoid switching station, cell switchgear house, in transformer station humid environment, dust etc. influence.The electric elements of switch cubicle are made preferably to work.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 is a kind of system flow chart of the dustless falling temperature technique of controller switching equipment of the invention.
Embodiment
Make further details of elaboration to the present invention below in conjunction with the accompanying drawings.
Refering to Fig. 1.
A kind of dustless falling temperature technique of controller switching equipment of embodiment one, comprises the following steps：
The first step, the heat transfer that the copper heat exchanger for being fitted in busbar both sides by silica gel produces incoming-line busbar and feeder line busbar is to insulating oil；
Second step, when insulating oil is heated to 60 DEG C, insulating oil is converged by aluminium oxide ceramics pipeline enters switching station, cell switchgear house, the lithium bromide refrigerator outside transformer station, and insulating oil drops to 55 DEG C by 60 DEG C；During this, the chilled water that refrigeration machine cooling offer circulating cooling coolant-temperature gage drops to 16 DEG C, 16 DEG C from 23 DEG C enters switching station, cell switchgear house, transformer station with the air heat-exchange in space, and refrigeration coolant-temperature gage is increased to 23 DEG C.
Embodiment two, based on embodiment one, the heat that incoming-line busbar and the feeder line busbar is produced accounts for the 50% to 60% of whole switch cubicle.
Embodiment three, based on embodiment two, the heat that incoming-line busbar and the feeder line busbar is produced accounts for the 55% of whole switch cubicle.
Embodiment four, based on embodiment three, the copper heat exchanger is made up of several parts：Busbar heat exchanger, busbar heat exchanger card, alumina ceramic tube etc. are constituted.Busbar heat exchanger is placed on the wider both sides of busbar, is bonded using silica gel with busbar, while being fixed using busbar heat exchanger card.Because there is the function of insulating paint, silica gel bonding and heat transfer outside busbar；Busbar heat exchanger card plays fixation；The effect of busbar heat exchanger is that the oil of heat cycles makes temperature be increased to 60 DEG C from 55 DEG C, and alumina ceramic tube plays a part of the pipeline outside connection and plays insulation；Expansion joint plays thermal expansion supplementary function, it is to avoid the impact of temperature heat exchanging device and alumina ceramic tube.
This technique of advantages of the present invention has the advantage that：
1 by ambient influnence, dustless, moisture-resistant and temperature stabilization, and being delivered in closed space for heat of the present invention is carried out, and is not disturbed by ambient temperature, humidity, dust, equilibrium temperature is reached using the heat of itself（Refrigeration is also more simultaneously more than the heat of generation, and final indoor temperature can be maintained at equilibrium temperature）；
2 sealings, safer avoids safe operation of the toys such as mouse to equipment from impacting；
The overall performance of 3 elements is improved, the temperature reduction of element, performance increase；
4th, reduce due to the heat impact that unexpected load or other reasons are caused, temperature is no more than 70 DEG C；
5th, bonded using silica gel, and special clamp is made using insulating materials and fixed, do not influence electric current.
