The invention discloses a kind of substation equipment failure method for inspecting.It is the following steps are included: S1: infrared video camera acquisition while the Infrared Thermogram comprising first object equipment and the second target device, and sends it to computer；S2: computer determines the temperature A of first object equipment and the temperature B of the second target device according to Infrared Thermogram；S3: judgement | A-B | whether it is greater than preset threshold X if so, thening follow the steps S4 and otherwise judges that first object equipment and the second target device are all normal；S4: if A > B, judging first object equipment overtemperature failure, if A < B, judges the second target device overtemperature failure.The present invention carries out breakdown judge using relative temperature difference, can quickly be found to the excessively high equipment of temperature, positioning failure equipment, carries out quick response convenient for related maintenance personnel.
Description
Technical field
The present invention relates to equipment routing inspection technical field more particularly to a kind of substation equipment failure method for inspecting.
Background technique
Currently there are substation's detection device be usually rely on single absolute temperature thermometric, due to environment temperature
The variation of degree in Various Seasonal and round the clock, needs to adjust thermometric alarm threshold in time, can just find faulty equipment in time.
For example, if in summer, close to 35 DEG C, normal electrical equipment temperature under the irradiation of the sun will connect daylight environment temperature
Nearly 50 DEG C or higher, if it is desired to faulty equipment be found by temperature, then alarm threshold needs to be arranged to 80 DEG C, if in evening
Upper or weather turns cold, and when environment temperature only has 10 DEG C, alarm threshold remains set to 80 DEG C, then early warning system cannot be sent out in time
Existing electrical equipment failure itself, system availability reduce, and need to improve the respond of whole system using more effective
Method judges equipment fault.
Summary of the invention
In order to solve the above technical problems, The present invention provides a kind of substation equipment failure method for inspecting, use phase
Breakdown judge is carried out to temperature difference, the excessively high equipment of temperature can quickly be found, positioning failure equipment, associated maintenance people is convenient for
Member carries out quick response.
To solve the above-mentioned problems, the present invention is achieved by the following scheme:
A kind of substation equipment failure method for inspecting of the invention, comprising the following steps:
S1: infrared video camera acquisition while the Infrared Thermogram comprising first object equipment and the second target device, and will
It is sent to computer；
S2: computer determines the temperature A of first object equipment and the temperature B of the second target device according to Infrared Thermogram；
S3: judgement | A-B | whether it is greater than preset threshold X if so, thening follow the steps S4 and otherwise judges first
Target device and the second target device are all normal；
S4: if A > B, judging first object equipment overtemperature failure, if A < B, judges that the second target device is super
Reviewing knowledge already acquired barrier.
In the present solution, target device is transformer, mutual inductor or other power equipments.First object equipment and the second mesh
Marking device is same category of device.First object equipment and the temperature of the second target device theoretically should be close when working properly,
Two target devices of discovery have the larger temperature difference after such as calculating, then it is assumed that the high target device operation irregularity of temperature, and monitoring is tied
Fruit issues maintenance personnel.
Preferably, computer screen shows Infrared Thermogram, and staff manually selects red in the step S2
First object equipment region and the second target device region on outer thermography.
Preferably, computer sets the maximum value in all temperature values in first object equipment region as first object
Standby temperature A, using the maximum value in all temperature values in the second target device region as the temperature B of the second target device.
Preferably, when computer judges some target device overtemperature failure, issuing alarm in the step S4, leading to
Know that staff overhauls in time.
Preferably, the first object equipment and the second target device are same category of device.
The beneficial effects of the present invention are: carrying out breakdown judge using relative temperature difference, the excessively high equipment of temperature can be carried out fast
Speed discovery, positioning failure equipment carry out quick response convenient for related maintenance personnel.
Detailed description of the invention
Fig. 1 is the work flow diagram of embodiment.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of substation equipment failure method for inspecting of the present embodiment, as shown in Figure 1, comprising the following steps:
S1: infrared video camera acquisition while the Infrared Thermogram comprising first object equipment and the second target device, and will
It is sent to computer；
S2: computer screen shows Infrared Thermogram, and staff manually selects the first mesh on Infrared Thermogram
Marking device region and the second target device region；
Computer is using the maximum value in all temperature values in first object equipment region as the temperature of first object equipment
A, using the maximum value in all temperature values in the second target device region as the temperature B of the second target device；
S3: judgement | A-B | whether it is greater than preset threshold X, otherwise X ≠ 0 judges if so, thening follow the steps S4
First object equipment and the second target device are all normal；
S4: if A > B, judging first object equipment overtemperature failure, if A < B, judges that the second target device is super
Reviewing knowledge already acquired barrier；
When computer judges some target device overtemperature failure, alarm is issued, staff is notified to overhaul in time.
Target device is transformer, mutual inductor or other power equipments.First object equipment and the second target device are same
Class equipment.First object equipment and the temperature of the second target device theoretically should be close when working properly, such as calculate first
The absolute value of the difference of the temperature B of the temperature A and the second target device of target device | A-B | it is greater than threshold X, then it is assumed that two mesh
Have the excessively high failure of target device temperature in marking device, by comparing the size of A and B, it is believed that temperature it is higher that
Target device operation irregularity, and monitoring result is issued into maintenance personnel.
Such as: original power failure early warning system alarm temperature at summer is 80 DEG C, and the part temperatures of normal work are
50 DEG C, the temperature rise that faulty equipment needs 30 DEG C can be by system alarm；When winter, environment temperature is 0 DEG C, and equipment works normally
Temperature is 10 DEG C, and faulty equipment, which needs temperature rise to be more than 70 DEG C, to be alerted by early warning system.Using failure inspection side of the invention
Method, no matter summer and winter faulty equipment are more than 30 DEG C and can quickly be found, and the threshold X is adjustable parameter, user Ke Gen
It is configured according to the needs of oneself, significantly very high system availability, can find faulty equipment in first time, ensure that electric power becomes
Electric power station system safety.
