At present, the control units of the nitrogen-filled fire extinguishing systems of the three single-phase transformer trucks are integrally installed on the accessory truck, and are connected to the nitrogen-filled fire extinguishing devices on the three single-phase transformer trucks through multiple cables. Occupy a lot of space on the accessory car, increase the design length of the accessory car, and increase the cost
At the same time, this installation method requires a lot of on-site wiring work, which is time-consuming and labor-intensive.

The invention provides a control unit of a nitrogen charging fire extinguishing system. The control unit comprises three local control units (10) which are configured to be correspondingly arranged on a single-phase transformer vehicle. Each local control unit comprises a controller (12) and a communication module (14). Each controller is constructed to be capable of being connected with a valve and a sensor of a nitrogen charging fire extinguishing device, wherein the valve is controlled according to the collection quantity of the sensor and preset logic. Each communication module is connected with the corresponding controller, wherein the communication module is constructed to be capable of being connected with a data acquisition and monitoring control system through a communication cable (16) with an interface connector, and the communication module is configured to be capable of receiving and forwarding the acquisition quantity of the sensor, the state of the valve and a control signal used for controlling the controller. The control unit can reduce the size and cost of an accessory vehicle of the vehicle-mounted mobile transformer, and facilitates field wiring. The invention further provides a nitrogen charging fire extinguishing system with the control unit and a vehicle-mounted mobile transformer.
Description
technical field [0001] The invention relates to a control unit, in particular to a control unit for a nitrogen-filled fire extinguishing system. The invention also relates to a nitrogen-filled fire extinguishing system and a vehicle-mounted mobile transformer provided with the above-mentioned control unit. Background technique [0002] Single-phase vehicle-mounted mobile transformers are used in various emergency power supply situations such as substation expansion and maintenance, and are generally equipped with three single-phase transformer vehicles and one accessory vehicle. In terms of the safe operation of mobile single-phase transformers, there is a need to install a nitrogen-filled fire extinguishing system for the transformer. At present, the control units of the nitrogen-filled fire extinguishing systems of the three single-phase transformer trucks are integrally installed on the accessory truck, and are connected to the nitrogen-filled fire extinguishing devices ...
