Abstract
The present invention relates to a kind of method for differentiating transformer drop and holding deisgn product, this method includes：The first step, found using thermal infrared imager at the Transformer Winding hottest point in steady-working state；Second step, actual temperature value herein is measured using infrared radiation thermometer；3rd step, insulating materials used in the above-mentioned actual temperature value measured and the transformer is contrasted in insulation system temperature data specified in GB 1094.11；4th step, if the actual temperature value measured is more than defined insulation system temperature, it is the product that drop is installed with after meter to be determined as the transformer.The present invention solves field condition and concludes whether power transformer product is that transformer drop is installed with the product after meter; conclude whether power transformer product meets rated capacity; this method is simple and reliable; save reception time and check and accept cost; simultaneously; the safety of power network is protected, is laid the foundation for continuous uninterrupted power supply.
Description
Technical field
The invention belongs to power system transformer technical field, particularly a kind of side for differentiating transformer drop and holding deisgn product
Method.
Background technology
At present because transformer primary material price soars, cause transformer manufacturers profit more and more thinner, to taking a step to be difficult
Bottom.As country advocates the requirement of establishment conservation-minded society and energy-saving and emission-reduction, former run time is not grown and changed
The transformer of first generation original unification of the motherland design carry out volume reduction transformation, make up to or the mark close to new type transformer
Standard, slow down transformer and eliminate to get off to sell the situation of waste product,
But the product being installed with for transformer drop after meter, manufacturer often and it is indefinite mark, but press novel product
There is provided, and drop be installed with meter after product often rated capacity is difficult to meet, product can bring threat to whole power network, so, change
Depressor will be identified the power transformer product dropped after being installed with meter using unit, it is ensured that the reasonable application of product, avoid power network
Infringement.
The content of the invention
The purpose of the present invention be in view of the shortcomings of the prior art, and propose it is a kind of differentiate transformer drop hold deisgn product side
Method.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of method for differentiating transformer drop and holding deisgn product, it is as follows that the method comprising the steps of：
The first step, found using thermal infrared imager at the Transformer Winding hottest point in steady-working state；
Second step, actual temperature value herein is measured using infrared radiation thermometer；
3rd step, insulating materials used in the above-mentioned actual temperature value measured and the transformer is provided in GB 1094.11
Insulation system temperature data contrasted；
4th step, if the actual temperature value measured is more than defined insulation system temperature, it is determined as that the transformer is
Drop is installed with the product after meter.
Moreover, when the actual temperature value measured is more than defined insulation system temperature, further by transformer body
Insulating materials samples, and is heated in drying or curing oven, sees change and the carbonizing degree of its color, to confirm product actual insulation
Material is identical with product nominal insulation material.
The advantages and positive effects of the present invention are：
1st, the present invention is solved because field condition is limited, it is impossible to is concluded with the method for " temperature rise test " in type approval test
Whether transformer meets the problem of rated capacity, and this method is simple and reliable, saves reception time and checks and accepts cost；
2nd, the inventive method has effectively prevented the use of rated capacity deficiency product, protects the safety of power network, is continuous
Uninterrupted power supply lays the foundation.Its method is simple and reliable.
Embodiment
Present invention implementation is further described below, following examples are descriptive, are not limited, it is impossible to
Protection scope of the present invention is limited with this.
A kind of method for differentiating transformer drop and holding deisgn product, it is as follows that the method comprising the steps of：
The first step, found using thermal infrared imager at the Transformer Winding hottest point in steady-working state；
Second step, actual temperature value herein is measured using infrared radiation thermometer；
3rd step, insulating materials used in the above-mentioned actual temperature value measured and the transformer is provided in GB 1094.11
Insulation system temperature (insulation grade anti-corrosion) data contrasted；Clear stipulaties transformer material therefor in GB 1094.11
Insulation system temperature (insulation grade anti-corrosion) and the winding under rated current temperature limit：
4th step, if the actual temperature value measured is more than defined insulation system temperature, it is determined as that the transformer is
Drop is installed with the product after meter.
In the specific implementation of the present invention, if the actual temperature value measured is more than defined insulation system temperature, it is
Prevent manufactory from, the artificial raising one-level of TRANSFORMER INSULATING MATERIAL, such as dry become of poured with epoxy resin of the F levels of reality is said into
It is H levels, but actual or F levels, this is that naked eyes can not distinguish, the fact that hold, pin drop in concealment that thus can be openly and legally
To such a situation, during Product Acceptance Review can scene transformer body insulating materials is sampled, producer is dry or curing oven in, will
Insulation system temperature heating of the insulating materials sample as described in producer, change and the carbonizing degree of its color are seen, to confirm product
The actual insulation system temperature (insulation grade anti-corrosion) of insulating materials.
Claims (2)
- A kind of 1. method for differentiating transformer drop and holding deisgn product, it is characterised in that it is as follows that the method comprising the steps of：The first step, found using thermal infrared imager at the Transformer Winding hottest point in steady-working state；Second step, actual temperature value herein is measured using infrared radiation thermometer；3rd step, by insulating materials used in the above-mentioned actual temperature value measured and the transformer exhausted specified in GB 1094.11 Edge system temperature data are contrasted；4th step, if the actual temperature value measured is more than defined insulation system temperature, it is that drop is held to be determined as the transformer Product after design.
- 2. the method according to claim 1 for differentiating transformer drop and holding deisgn product, it is characterised in that：When the reality measured When temperature value is more than defined insulation system temperature, further transformer body insulating materials is sampled, in drying oven or solid Change and heated in stove, change and the carbonizing degree of its color are seen, to confirm product actual insulation material and product nominal insulation material It is identical.
