Tips: Application of burglar alarm in isolation transformer
Since outdoor transformer is often stolen, the product such as 80kVA isolation transformer burglar alarm that can effectively protect the outdoor transformers and solve the problem that power workers deal for many years. Burglar alarm device is installed next to transformer or on the telegraph pole. Once a front-end processor detects disconnection and power failure, it will sent GSM message to the four alarm personnel and alarm information to monitoring center, at the same time it will trigger the voice alarm of on-site loudspeaker. The step up and step down transformer that sends out the alarm information and the actual location of faulty line are clearly displayed on the electronic map of monitoring center. After receiving the alarm, the police on duty will immediately be sent to the scene to have a check and deal with the related problem. In addition to disconnection and warning, the machine can access to the alarm amount of vibration, infrared ray, wire wrapping and others for the purpose of protecting the transformer safety.
