Description
Technical field
The utility model relates to a kind of power test device, specifically is the series resonance Withstand test device that is used for primary equipment AC voltage withstand test such as 110kv cross-inked polyethylene power cable, combined electric.
Background technology
Along with the electric network reconstruction input increases year by year, transformer station's new structure Design Mode is occupied an leading position, the new structure pattern---be that cable passes in and out line+GIS, COMPASS, PASS unit equipment.The establishment of this pattern has also just brought the frequent of GIS combined electrical apparatus and the commissioning test of inlet wire cross-inked polyethylene power cable.Use complete series resonance Withstand test device to carry out cross-inked polyethylene power cable, combined electric primary equipment AC voltage withstand test such as (GIS, COMPASS, PASS).This test unit is convenient to transportation, on-the-spot easy to use, for positive role has been played in the safe operation that guarantees primary equipment.
But also there is following problem in this test unit, because of operation outside master station is exposed to, so equate with the environment temperature at scene.It is also just unavoidable situation subzero and temperature more than 40 degrees centigrade to occur.Its LCD display is common single colour liquid crystal display, and owing to himself intrinsic characteristic, it is too high or too low for temperature in addition to exceed operating temperature range, all can cause the phenomenon of improper demonstration to produce.Temperature is crossed low display screen does not have demonstration, the too high display screen blank screen of temperature.And electronic device temperature nargin is little, and the oneself requirement operating temperature range is little, and too high or too low for temperature all can and the measurement calculating produces error, even function is stagnated.Electronic component also can be subjected to larger interference when humidity was too high.
Because when the problems referred to above caused system start-up, the stand-by period also prolonged, thereby causes the commissioning test time lengthening, causes equipment to put into operation thereupon on schedule.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of series resonance Withstand test device, it can be under the mal-condition of low temperature or high temperature operate as normal.
In order to address the above problem, the utility model is by the following technical solutions: a kind of series resonance Withstand test device, comprise housing, housing bottom is the switch board that CPU and electrical equipment are installed, case top is provided with guidance panel and two LCD LCDs, it is characterized in that: be provided with refrigerating plant near LCD LCDs place, described refrigerating plant connects CPU by temperature controller, near on the housing of LCD LCDs heating arrangement is installed, described heating arrangement comprises well heater, after connecting with the forced convertion fan, forced convertion fan, well heater be electrically connected with CPU by temperature controller.
As further technical scheme of the present utility model: described refrigerating plant is two semiconductor coolers, is separately positioned on the back side of two LCD LCDs.
Technical scheme further: described semiconductor cooler is provided with heat radiator.
The beneficial effects of the utility model are: under too high, the low excessively environment temperature of temperature, obviously shorten its start-up time; Eliminated the phenomenon of LCD LCDs flower screen or blank screen; Save the working time, reduced labour intensity, reduced unnecessary link, avoided reciprocal sex work, improved the test efficiency of series resonance Withstand test device.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a schematic block circuit diagram of the present utility model.
Embodiment
As shown in drawings, this series resonance Withstand test device comprises housing, and housing bottom is the switch board that CPU and electrical equipment are installed, and case top is provided with guidance panel and two LCD LCDs.
Be provided with refrigerating plant near LCD LCDs place.Described refrigerating plant is two semiconductor coolers, is separately positioned on the back side of two LCD LCDs.Two semiconductor refrigerators connect CPU by temperature controller.
Near on the housing of LCD LCDs heating arrangement is installed, described heating arrangement comprises well heater, forced convertion fan, is electrically connected with CPU by temperature controller after well heater is connected with the forced convertion fan.Well heater is not installed in is close to LCD LCD place, when preventing that its temperature is too high electronic component is caused damage.
Can set a temperature range by temperature control, the minimum temperature of this temperature range is the heating starting temperature, and maximum temperature is the cooling activation temperature.
Too high when environment temperature, when surpassing the maximum temperature of said temperature scope, start semiconductor cooler by temperature controller, thereby can reduce working temperature, guarantee that system starts fast and LCD normally shows.Semiconductor cooler uses lower operating voltage, can satisfy the job requirement of cooling electronic device fully, thereby guarantees operate as normal.
When environment temperature is crossed low or humidity when excessive, when being lower than the minimum temperature of said temperature scope, start heating arrangement by temperature controller, the fan of forced convertion simultaneously also starts, make the zonule around the LCD LCDs form forced convertion, improve the temperature of subenvironment around it and reduce humidity, guarantee that system starts fast, operate as normal.Temperature sensor in the temperature controller comes the sensing device working temperature, after arriving design temperature, stops heated condition, effectively guaranteed constant environment temperature, prevent that heating arrangement from heating simply, cause device to enter the hot operation state, make it produce the demonstration fault once more.
As other embodiments: in order to guarantee refrigeration and convenient heat radiation, finned as required on the semiconductor cooler.
Refrigerating plant also can adopt compressor to add the mode of condenser, though can play refrigeration preferably, cost is higher, and system installs complicated, is not suitable for equipment actuality.So preferred semiconductor refrigeration device.
