Abstract
The utility model discloses a temperature relay test device. The device is characterized in that the test device comprises a thermal conductor and a heater; the thermal conductor is provided with a plurality of grooves which can accommodate a relay with a temperature to be measured and at least one fixing groove which accommodates the heater; the heater is arranged in the heater fixing groove; the heater uses a PTC heating source and can adjust a temperature rise and cooling through an adjustable transformer. The test device adopts a PTC heating component with a small size as a heating element so that a size of a whole heating device is reduced and operation is convenient. A heating rate can be conveniently and accurately controlled and simultaneously energy consumption of the temperature relay during a test is reduced.
Description
Technical field
The utility model relates to a kind of relay proving installation, is a kind of proving installation of temperature relay specifically.
Background technology
Temperature relay is a kind of controller of temperature variation control circuit break-make that passes through, and plays the superheat protecting function to other device on circuit, very extensive in the application in each field.High-precision temperature relay is even more important to the various devices on circuit, and it can accurately be controlled temperature and circuit and device are not burned and can work.Therefore, the performance test of temperature relay just seemed to extremely important.At present, what this temperature relay test was adopted is the high-temperature blast baking oven, and test there will be operation inconvenience in this way, and heating rate is uncontrollable, the shortcomings such as non-uniform temperature in baking oven, and also energy consumption is larger.Be badly in need of a kind of simple in structure, control accuracy is high, volume is little and energy consumption is little temperature relay proving installation.
Summary of the invention
The utility model, for solving the problems of the technologies described above, provides a kind of temperature relay proving installation, can meet requirement simple in structure, that control accuracy is high, volume is little and energy consumption is little.
Realize that the technical solution of the utility model is: a kind of temperature relay proving installation, described proving installation comprises heat conductor, well heater; Described heat conductor is provided with a plurality of grooves that hold temperature relay to be measured, and is provided with the pickup groove that at least one holds well heater, and described well heater is placed in the well heater pickup groove.
Described heat conductor is preferably aluminium sheet, copper coin or the iron plate that thickness can arrange the groove that holds temperature relay to be measured.
Described well heater is the PTC pyrotoxin be connected with transtat, can accurately control rising or the decline of heating-up temperature.
Described heat conductor, well heater preferably are placed in closed container, make test more accurate.
The beneficial effects of the utility model are: aluminium sheet, copper coin or iron plate are made heat conductor preferably to select thermal conductivity, tested temperature relay is fixed on heat conductor, the original paper that again PTC generated heat is embedded on heat conductor, then, add transtat at PTC heating original paper input front end, control the heating rate of PTC heating original paper by transtat.Like this, proving installation adopts the PTC heating original paper of small volume as heater, makes whole heating arrangement smaller volume, easy to operate, can facilitate and accurately control heating rate again, has reduced again the energy consumption of temperature relay test simultaneously.
The accompanying drawing explanation
The master of Fig. 1 proving installation looks schematic diagram
The schematic rear view of Fig. 2 proving installation
In figure, 1-heat conductor, 2-place the groove of temperature relay to be measured, 3-well heater pickup groove, 4-well heater.
Embodiment
As shown in Figure 1 and Figure 2, a kind of temperature relay proving installation, comprise that thickness can arrange aluminium sheet heat conductor 1 and the well heater 4 of the groove 2 that holds temperature relay to be measured; Described heat conductor 1 also is provided with at least one pickup groove that holds well heater 3, and described well heater 4 is placed in well heater pickup groove 3.Described well heater 4 is the PTC pyrotoxins that are connected with transtat, can accurately control rising or the decline of heating-up temperature.Temperature relay to be measured is placed in the groove of placement temperature relay to be measured of heat conductor, the original paper that simultaneously PTC generated heat is fixed in the well heater pickup groove of heat conductor reverse side 3, then heat conductor is placed in a closed container, switches on power and can carry out on off test to temperature relay.
The utility model adopts the PTC heating original paper of small volume as well heater, makes whole heating arrangement smaller volume, easy to operate, can facilitate and accurately control heating rate again, has reduced again the energy consumption of temperature relay test simultaneously.
