Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of dry-type reactor fire extinguishing, and particularly relates to a dry-type reactor fire extinguishing complete device. BACKGROUND

[0002] In the power system, the reactor has a wide application and is a key device for improving the power factor, adjusting the voltage and compensating the reactive power in the power grid. With the rapid development of the smart grid, wind power, photovoltaic and other new energy fields, the substation is gradually increasing, the demand for the reactor is increasing, and the reactor fire accidents are also increasing. How to quickly extinguish the fire after the reactor catches fire has become an urgent problem to be solved.

[0003] The existing reactor does not have a dedicated fire extinguishing complete device. After the fire, the operating personnel or the firemen use the manual method to spray the dry powder extinguishing agent or the water foam extinguishing agent. In the fire extinguishing process, the personnel face the fire risk and other personal safety risks. At present, there is a micro new fire extinguishing complete device specially used for the distribution box and the cabinet. This kind of device has a small size and can only be applied in the unattended, fire hazard existing and relatively closed small cavity type electrical cabinet. The research on the fire extinguishing complete device for the outdoor reactor, which is a large primary power equipment, is still relatively insufficient. Based on the above problems, a new dry-type reactor fire extinguishing complete device is needed. SUMMARY

[0004] The purpose of the present application is to overcome the deficiencies of the prior art and provide a dry-type reactor fire extinguishing complete device. The device uses intelligent spraying control and remote control, can achieve early fire extinguishing, efficient suppression, realizes the purpose of quickly extinguishing the reactor, and solves the problems in the background technology.

[0005] The purpose of the present application is achieved by a dry-type reactor fire extinguishing complete device, which comprises: an intelligent inspection host, which is used for communicating with an external intelligent auxiliary control system, monitoring the running state of a fire extinguishing complete assembly in real time, and executing a remote start instruction; a regional control unit connected with the intelligent inspection host, configured to receive a start signal and output a control instruction to a controller of the fire extinguishing complete assembly; the controller of the fire extinguishing complete assembly is connected with the regional control unit and triggers a fire extinguisher when receiving the control instruction; a medicament spraying and conveying device for conveying the fire extinguishing agent of the fire extinguisher to the fire location of the reactor after the fire extinguisher is triggered.

[0006] By integrating the intelligent inspection host: remote communication, state monitoring, instruction execution, regional control unit signal receiving and forwarding, fire extinguishing complete set controller power signal excitation, and specific agent injection delivery device, a fire extinguishing device dedicated to dry-type reactors is formed, which supports remote operation. The core idea is to realize efficient, safe (remote to avoid personnel close to high-risk areas), and partitioned management of automatic / semi-automatic fire extinguishing of the reactor fire through this hierarchical control architecture. It greatly improves the stability of the power grid, improves the operation and maintenance efficiency, and enhances the safety of operation and inspection personnel and equipment.

[0007] Further, the regional control unit includes a partition control mode, a manual mode, and an automatic mode; the partition control mode is used to start a single or multiple fire extinguishing complete sets individually or simultaneously; in the manual mode, state detection is used; and in the automatic mode, a remote start signal is received. Through the setting of the partition control mode, it allows flexible selection of starting a single or multiple fire extinguishing devices ("partitioning") according to the fire situation, providing more fine control capabilities and the possibility of resource optimization configuration, and solving the problems of dry-type reactor (possibly multiple or large area) fire location and efficient response coverage.

[0008] Further, the fire extinguishing agent is perfluorohexanone. By using perfluorohexanone as the fire extinguishing agent, it has the comprehensive advantages of environmental protection (no greenhouse effect, ODP=0), non-toxic (relatively safe), good insulation, no residue, high-efficiency fire extinguishing, etc., and is very suitable for dry-type reactor fire scenarios in transformer substations with high voltage, precision equipment, and personnel who may need to approach or be located indoors. It solves the problems of environmental protection, equipment damage, and insulation risk of existing agents (such as water, dry powder, and some gases) in the application of reactors.

[0009] Further, the intelligent inspection host includes a pressure acquisition module for real-time monitoring of the pressure state of the fire extinguisher and triggering an alarm when the pressure is below a set threshold. Through real-time pressure acquisition and pressure loss alarm functions, the reliability of the fire extinguishing device itself is ensured (pressure is a key parameter for normal storage and effective injection of the agent). When the pressure is insufficient (indicating possible leakage or insufficient agent), an alarm can be triggered in time, allowing maintenance personnel to perform maintenance before a fire occurs, greatly solving the "invisible" failure risk problem (i.e., the device itself cannot work normally at critical moments) of existing fire extinguishing systems, and improving the reliability and safety of the system.

[0010] Furthermore, the fire extinguishing system's controller includes a solenoid valve activation device, which is used to trigger the fire extinguisher in the high electromagnetic environment of the substation. Designed specifically for the harsh, high electromagnetic environment of the substation, this solenoid valve activation device serves as a key actuator in the controller. This solves the problem of conventional electronic triggering devices failing or malfunctioning under strong electromagnetic interference, ensuring that the fire extinguisher can be reliably triggered when needed most.

[0011] Furthermore, the agent injection and delivery device includes a frame, a movable seat is fixedly connected to the bottom of the frame, a telescopic assembly extending in the vertical direction is connected to the middle position of the upper surface of the movable seat, the upper end of the telescopic assembly is connected to a rotating seat, a plurality of spray pipes are fixedly provided on the upper surface of the rotating seat, and a plurality of spray heads are connected to the spray pipes. A delivery device structure with an adjustable (lifting + rotating) spray assembly is provided. The movable seat provides basic positioning, the telescopic assembly (which can be a hydraulic cylinder, electric push rod, etc.) realizes height adjustment, and the rotating seat realizes direction adjustment. This structure enables the spray head to accurately align with and effectively cover the complex, multi-layered honeycomb winding structure of the dry-type reactor, solving the problem of effective penetration and uniform coverage of the agent in the narrow winding gap.

[0012] Furthermore, the sprinkler head includes multiple wide-angle nozzles and multiple oblique-angle nozzles, evenly spaced and spaced apart. The oblique-angle nozzles are tilted at a 65° angle. This specific combination of wide-angle and oblique-angle nozzles combines the advantages of wide-angle coverage over large areas with the advantages of oblique angle penetration into narrow gaps (aligned with winding gaps). The 65° tilt angle, a targeted angle selected through practical application, optimizes the spray coverage efficiency and deep penetration of the agent within the complex reactor structure, ensuring comprehensive firefighting.

[0013] Furthermore, the spray pipe includes a central coil, which is connected to a plurality of extension tubes arranged at equal intervals along its circumference. The outer ends of the extension tubes are connected to an arc-shaped outer tube, and the spray head is mounted on the arc-shaped outer tube. By configuring a specific spray pipe structure, the central coil connects the radial extension tubes and the arc-shaped outer tube. This structure facilitates surrounding the dry-type reactor cylinder. It can be a cylindrical or prismatic structure arranged in an annular or arc shape. This allows the spray head mounted on the arc-shaped outer tube to form an enveloping, three-dimensional spray surface, improving the uniformity and efficiency of the surrounding coverage of the reactor by the agent.

[0014] Further, the intelligent inspection host machine is electrically connected with a real-time state display module, and the real-time state display module is used for visual display of the distributed position and pressure data of the fire extinguishing complete set. Through the real-time state display module, the distributed position and pressure data are visualized, which not only facilitates the operation and maintenance personnel to intuitively master the deployment state position of all fire extinguishing devices, but more importantly, can monitor the key parameter pressure in real time, provides instant and clear data support for decision-making whether to repair, where the fire alarm is started, etc., and improves the manageability and operation and maintenance efficiency of the system.

[0015] A method for using the above dry reactor fire extinguishing complete set, comprising the steps of: the operator remotely sends an instruction signal to the intelligent inspection host machine, the intelligent inspection host machine receives the remote start instruction, and sends the start instruction to the regional control unit, the regional control unit generates a partition control signal according to the instruction, and outputs a control instruction to the controller of the fire extinguishing complete set, the controller of the fire extinguishing complete set outputs 24V power to trigger the fire extinguisher, after the fire extinguisher is triggered, the medicament spraying and conveying device drives the frame and the fire extinguisher to move through the moving seat, and moves the perfluorohexanone medicament to the fire position, sprays the perfluorohexanone through the spray head, realizes the rapid fire extinguishing of the reactor, protects the safety of the operator, and greatly improves the safety. The medicament spraying and conveying device automatically adjusts the spraying direction and height by using PLC control during the perfluorohexanone medicament conveying process.

[0016] The application has the following advantages: by integrating the intelligent inspection host machine remote communication, state monitoring, instruction execution, regional control unit signal receiving and forwarding, fire extinguishing complete set controller power signal triggering, and specific medicament spraying and conveying device, a fire extinguishing device special for dry reactors is formed, which supports remote operation. The automatic / semi-automatic fire extinguishing of the reactor can be realized in an efficient, safe (remote operation avoids personnel approaching high-risk areas) and partitioned manner. The operation stability of the power grid is greatly improved, the operation and maintenance efficiency is improved, and the safety of the operation and inspection personnel and equipment is improved. By using perfluorohexanone as the fire extinguishing medicament, the comprehensive advantages of environmental protection, no greenhouse effect, non-toxicity, good insulation, no residue, high efficiency, etc. are achieved, which is very suitable for the dry reactor fire extinguishing scene of the substation with high voltage, precision equipment and personnel who may need to approach or be located in an indoor environment. The problems of environmental protection, equipment damage and insulation risk of existing medicaments (such as water, dry powder and some gases) in the application of reactors are solved.

[0017] By setting up a conveying device structure with an adjustable lifting and rotating spray component, the mobile seat provides basic positioning, the telescopic component can be a hydraulic cylinder, an electric push rod, etc. for achieving height adjustment, and the rotating seat achieves direction adjustment. This structure enables the spray head to accurately align with and effectively cover the complex, multi-layered honeycomb winding structure of the dry-type reactor, solving the problem of effective penetration and uniform coverage of the agent in the narrow winding gap. By setting up a specific spray pipe structure, the central coil connects the radial extension tube and the arc-shaped outer tube. This structure is conducive to surrounding the dry-type reactor column. It can be a cylindrical or prismatic structure for an annular or arc-shaped arrangement, so that the spray head set on the arc-shaped outer tube can form an enveloping, three-dimensional spray surface, improving the uniformity and efficiency of the agent's surrounding coverage of the reactor as a whole.
