Embodiment 1

[0023] Example 1, such as figure 1 As shown, a transformer power failure alarm method is characterized in that the method comprises the following steps:

[0024] Step 1, using the monitor 1 to monitor the electrical signal at the output end of the transformer in real time, while using the locator 2 to monitor the transformer position signal in real time and using the temperature sampler 7 to monitor the transformer temperature signal in real time;

[0025] Step 2, the monitor 1 generates a low-voltage signal and a low-current signal in response to the electrical signal at the output terminal of the transformer, and transmits the signal to the voltage-current converter 3;

[0026] Step 3, the voltage-to-current converter 3 generates a digital signal in response to the low-voltage signal and the low-current signal, and transmits it to the controller 4;

[0027] Step 4, the controller 4 responds to the digital signal, the transformer position signal and the temperature signal at...

Abstract

The invention relates to a transformer power-off alarm method and device. The alarm method includes the following steps: a monitor is utilized to monitor a transformer output end electrical signal inreal time; the monitor generates a low voltage signal and a low current signal in response to the transformer output end electrical signal, and transmits the signals to a voltage and current converter; the voltage and current converter generates digital signals in response to the low voltage signal and the low current signal and transmits the signals to a controller; when abnormality occurs in thedigital signals, the controller generates an alarm request signal and sends the signal to a server; and the server responds to the alarm request signal and sends alarm information to maintenance personnel. The transformer power-off alarm method solves the problem that an ordinary transformer power-off alarm system can only monitor the running state of one transformer and cannot monitor a plurality of transformers, and arrangement of a power module provides stable power supply for an alarm device, thereby improving security and practicability of the system.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a transformer power failure alarm method and device. Background technique [0002] Transformers are important equipment for power transmission in substations and play a very important role. Transformers usually cause damage to components due to overload operation and high temperature, and power outages due to line faults. Due to the scattered and inaccurate repair locations of users, it is easy to cause overtime repairs and give Inconvenience to users. The existing transformer power failure alarm system, such as a transformer power failure alarm system announced by patent announcement number CN204721095U, includes a signal acquisition device, a wireless signal transmitter, a wireless signal receiving device and a position line simulation device. The position line simulation device includes The voice prompt module, the signal processing module and the LED position display mo...
