Description

Technical Field

[0001] The utility model relates to the field of power application, in particular to a switch transformer oil leakage detection device based on NBIOT technology. Background Art

[0002] At present, it has been found that the working cylinder and valve inside the hydraulic switch of the power system are leaking oil; the primary and secondary bushings on the upper part of the transformer are leaking oil, and the oil leakage of the cooler is using the observation method, which requires the operating personnel to patrol the substation to discover it. However, due to the patrol time and the relatively hidden location of the oil leakage, it is not easy to discover the oil leakage fault in time, which not only affects the appearance and pollutes the environment, but also lowers the oil level and causes the transformer to lose pressure, making the live joints and switches in an oil-free insulation state. At the very least, it reduces the insulation quality and service life of the switches and transformers, and affects the operation and maintenance personnel's judgment on the oil gauge indication and other conditions; at worst, it leads to insulation degradation, breakdown, short circuit, burning and even explosion, which seriously threatens the safety of the power grid and operators.

[0003] Therefore, developing a device that can solve the problem of oil leakage in hidden positions of switches and transformers that cannot be discovered in time has become a problem that people are eager to solve. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a switch transformer oil leakage detection device based on NBIOT technology.

[0005] The technical solution provided by the utility model is: a switch transformer oil leakage detection device based on NBIOT technology, a battery replacement cover, a battery box, a battery, a T-type socket, a wire, a voltage stabilizing circuit module, an oil level detection height adjustment bolt, an oil and water detection sensor, a probe, an NBIOT communication module, a control chip and a bottom plate;

[0006] Among them, the control chip, oil and water detection sensor, and NBIOT communication module are powered by the voltage-stabilizing circuit module, and the oil and water detection sensor is connected to the control chip. The principle that light is refracted in liquid and cannot make the receiver receive the signal is used to detect oil leakage and rainwater. Two probes are connected to the control chip, and the conductivity of water and the insulation of oil are used to distinguish oil and rainwater. When it rains, the two probes are turned on. When the insulating oil leaks, the two probes are not turned on, and the oil and water detection sensor has a signal. The NBIOT communication module technology is used to send alarm signals to the mobile phones and computers of the operation and maintenance personnel, thereby achieving the purpose of real-time detection of oil leakage in hidden parts and alarm.

[0007] Preferably, the entire device is powered by a 7.2 volt lithium battery.

[0008] Further preferably, a water-blocking plate is provided under the voltage-stabilizing circuit module, NBIOT communication module and control chip, and the water-blocking plate separates the inside of the device to prevent the oil-water detection sensors and probes below from contacting oil and water during the detection process and causing a short circuit in the upper charged module.

[0009] Further preferably, the oil-water detection sensor and the probe are mounted on a base plate, and the oil level detection height adjusting bolt can adjust the probe detection position and height by turning the height adjusting bolt.

[0010] Further preferably, the battery supplies power to the control chip, NBIOT communication module and oil-water detection sensor through the voltage stabilizing circuit module. When oil and water are present, the trigger signal is high level, when there is no water in the probe, it is low level, and when there is water, it is high level. When one signal is high and the other is low, it proves the existence of oil leakage, and an alarm is sent to the mobile phone and computer of the operation and maintenance personnel through the communication module.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] The utility model has the advantages of simple structure, convenient operation, safety, reliability and space saving. The control chip, the oil-water detection sensor and the NBIOT communication module are powered by a voltage-stabilizing circuit module. The oil-water detection sensor is connected to the control chip. The principle that the light is refracted in the liquid and the receiver cannot receive the signal is utilized to detect the occurrence of oil seepage and rainwater. The two probes are connected to the control chip. The electrical conductivity of water and the insulation of oil are utilized to distinguish between oil and rainwater. When it rains, the two probes are in a conducting state. When the insulating oil leaks, the two probes are not conducting. The oil-water detection sensor has a signal. The NBIOT communication module technology is utilized to send an alarm signal to the mobile phones and computers of the operation and maintenance personnel for inspection, thereby achieving the purpose of real-time detection of oil seepage in hidden parts and alarm.
