Abstract
This utility model provides a kind of critesistor mounting structure for inverter, including casing and PCB, described PCB is provided with critesistor, described casing is provided with a boss, described boss is corresponding with described critesistor position, and described critesistor abuts on described boss.This critesistor mounting structure directly detects the temperature of casing convex platform by critesistor, owing to casing itself uses the preferable metal material of heat conductivity, therefore temperature equalizes accordingly, therefore the temperature conditions in casing more can be reflected by the temperature of detection casing, therefore measure the most accurate.Adopting in this way again, the installation site of critesistor is relatively fixed, and therefore assembles more aspect, can directly use the mode paster of SMT to install, can effective assembling speed, reduce recruitment cost.
Description
Technical field
This utility model relates to technical field of photovoltaic power generation, particularly to a kind of critesistor mounting structure being used in photovoltaic DC-to-AC converter.
Background technology
Along with the day by day shortage of the energy and day by day increasing the weight of of environmental pollution, clean energy resource, regenerative resource become the field that current countries in the world are given priority to, wherein photovoltaic power generation technology because of its there is green, environmental protection, the advantage such as renewable are increasingly subject to people's attention and welcome.In photovoltaic power generation technology, for the direct current energy that photovoltaic module produces being converted to the critical component that the inverter of AC energy is whole photovoltaic power generation technology.
In photovoltaic DC-to-AC converter, heater element on circuit board is more, if can not well carry out dispelling the heat, the temperature in inverter box body likely can be made to raise, and thus can affect the normal work of inverter circuit, even can burn electrical equipment time serious, make photovoltaic DC-to-AC converter break down.In existing photovoltaic DC-to-AC converter circuit; in order to prevent electrical equipment from burning; critesistor would generally be set in photovoltaic DC-to-AC converter circuit; the temperature within photovoltaic DC-to-AC converter is detected by critesistor; when temperature reach a certain height, critesistor can send feedback signal and makes equipment downtime or send alarm signal.In inverter circuit, critesistor is directly placed in inverter cabinet after being mostly mostly to be to be connected by connecting line at present.This mode has following defects that 1) temperature survey is inaccurate, owing to mostly critesistor is arbitrarily placement certain position in the chassis, and cabinet is more due to electric elements inside, the most all can there is temperature difference, the temperature of critesistor detection can not the temperature of actual response cabinet inside；2) wiring is relatively complicated, and critesistor needs to be fixed by wire rod and screw, needs by manually assembling, and speed is relatively slow, cost of labor is high.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of critesistor mounting structure that critesistor can be made accurately to detect temperature in inverter.
For achieving the above object and other relevant purposes, this utility model provides a kind of critesistor mounting structure for inverter, including casing and PCB, described PCB is provided with critesistor, described casing is provided with a boss, described boss is corresponding with described critesistor position, and described critesistor abuts on described boss.
Preferably, heat conduction mud it is provided with between described critesistor and described boss.
Preferably, described boss is provided with groove, and described heat conduction mud is positioned at described groove.
Preferably, described critesistor is pasted sheet type thermistor.
Preferably, described boss is positioned on the base plate of described casing, and described boss is positioned at the middle part of described base plate.
As mentioned above, critesistor mounting structure of the present utility model has the advantages that this critesistor mounting structure directly detects the temperature of casing convex platform by critesistor, owing to casing itself uses the preferable metal material of heat conductivity, therefore temperature equalizes accordingly, therefore the temperature conditions in casing more can be reflected by the temperature of detection casing, therefore measure the most accurate.Adopting in this way again, the installation site of critesistor is relatively fixed, and therefore assembles more aspect, can directly use the mode paster of SMT to install, can effective assembling speed, reduce recruitment cost.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be understood other advantages of the present utility model and effect easily by the content disclosed by this specification.
Refer to Fig. 1,2.Notice, structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to coordinate the content disclosed in description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall in the range of the technology contents disclosed in this utility model obtains and can contain.Simultaneously, in this specification cited as " on ", D score, "left", "right", the term of " middle " and " " etc., it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, being altered or modified of its relativeness, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
As shown in Figure 1, 2, this utility model provides a kind of critesistor mounting structure for inverter, and this critesistor mounting structure includes casing 1 and PCB 2, and PCB 2 is fixed in impurity casing 1.PCB 2 is provided with critesistor 6, and critesistor 6 is for detecting the temperature in casing 1 inner chamber.Being provided with a boss 3 on casing 1, boss 3 is corresponding with critesistor 6 position, and critesistor 6 abuts on boss 3, detects the temperature on boss 3 by critesistor 6, and by corresponding conversion, so that it may calculate the temperature in cabinet.In order to detect the temperature in cabinet more accurately, boss 3 may be provided on the base plate of casing 1, and boss 3 is arranged on the middle part of base plate, and so temperature of detection is the most accurate.
In order to raising dielectric strength, heat conduction mud 5 can be set between critesistor 6 and boss 3.For the ease of placing, a groove 4 can be set on boss 3, heat conduction mud 5 is placed in this groove 4.Further, critesistor 6 can use pasted sheet type thermistor, thus can be by being printed in PCB 2 between SMT mode.
This critesistor mounting structure directly detects the temperature of casing convex platform by critesistor, owing to casing itself uses the preferable metal material of heat conductivity, therefore temperature equalizes accordingly, therefore the temperature conditions in casing more can be reflected by the temperature of detection casing, therefore measure the most accurate.Adopting in this way again, the installation site of critesistor is relatively fixed, and therefore assembles more aspect, can directly use the mode paster of SMT to install, can effective assembling speed, reduce recruitment cost.So, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by any person skilled in the art.Therefore, art has all equivalence modification or changes that usually intellectual is completed under without departing from the spirit disclosed in this utility model and technological thought such as, must be contained by claim of the present utility model.
