DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Examples, such as Figure 1-Figure 4 As shown: The utility model provides a capacitive reactance dedicated intrinsically safe explosion suppressor, which structure includes an electric control cabinet 1, on which a spray assembly 2 is installed, and the spray assembly 2 is installed on the electric control cabinet 1 through an adjustable directional assembly 3 installed on the top of the electric control cabinet 1, which is used to adjust and position the spray direction, and the cabinet of the electric control cabinet 1 includes control components and a communication module and is also provided with an inner compartment 4, and common control components include air switches, central controllers, etc., and also include temperature sensors for detecting the occurrence of fire, which will not be repeated here;

[0022] The spray assembly 2 includes a spray pipe 21, a spray head 22 installed at the end of the spray pipe 21, and a connecting pipe 23 installed at the other end of the spray pipe 21. The connecting pipe 23 is connected to the inner compartment 4 in the electric control cabinet 1. The inner compartment 4 is provided with a gas supply part a. The inner compartment 4 or the spray assembly 2 is provided with a fire extinguishing medium part b. The fire extinguishing medium part b is filled with a fire extinguishing medium. The gas supply part a is connected to the fire extinguishing medium part b so that the gas generated by the gas supply part a acts on the fire extinguishing medium. The control components of the electric control cabinet 1 are used to control the gas supply part a to supply gas to the fire extinguishing medium part b, so that the fire extinguishing medium is sprayed outward through the spray pipe 21 and the spray head 22.

[0023] In order to make the fire extinguishing medium driven by air pressure have a tendency to move in one direction as a whole, in this embodiment, the fire extinguishing medium part b is arranged in the injection assembly 2, and specifically, the fire extinguishing medium in the fire extinguishing medium part b is dry powder and is filled in the nozzle 21, and a sealing film 25 is provided at one end of the nozzle 21 close to the nozzle 22. In addition, a sealing film 25 is also provided at one end of the nozzle 21 close to the connecting pipe 23, so that the fire extinguishing medium is sealed and placed in the nozzle 21 as a whole, which is convenient for long-term storage, and the sealing film 25 can be sealed with a multi-layer aluminum film, and a desiccant is placed between the multi-layer aluminum films;

[0024] Moreover, in order to facilitate long-term storage, the gas supply part a in the internal warehouse 4 of the box is of a non-pressure storage form, and a solid-gas converter is arranged in the gas supply part a. The control components of the electric control cabinet 1 include a heating wire, and the heating wire is embedded in the solid-gas converter to heat the solid-gas converter to produce gas. The solid-gas converter known to those skilled in the art is usually a catalyst or reactant, which promotes the chemical reaction between solid and gas and produces gaseous products. Some common solid-gas converters include metal oxides, alkali metal compounds, hydrides and halides, etc. The heating wire generates heat according to the thermal effect of the electric current, and the heat generated excites the solid-gas converter to react and produce gas, which breaks through the aluminum film and drives the fire extinguishing medium to spray out.

[0025] Moreover, the directional assembly 3 includes a base 31 and a hinge seat 32 mounted on the base 31. The nozzle 21 is hingedly connected to the top of the electric control cabinet 1 through the hinge seat 32 so as to swing at the top of the electric control cabinet 1. In this embodiment, the nozzle 21 is bent, and the angle between the two ends of the nozzle 21 at the bend is less than or equal to ninety degrees. In this embodiment, a ninety-degree right angle is adopted. By giving the nozzle 21 an angle in advance, the nozzle 21 itself does not need to be bent and movable, so that the nozzle 21 can be installed and set as a solid whole, so as to better store the fire extinguishing medium, and the distance from the bend of the nozzle 21 to the hinge seat 32 is greater than the distance from the back of the electric control cabinet 1 to the hinge seat 32, so that the nozzle 21 can be folded and stored toward the back of the electric control cabinet 1 when it is not needed, so as to facilitate its transportation and on-site arrangement.

[0026] Moreover, the directional assembly 3 also includes an unfolding positioning disk 33 mounted on the base 31. The unfolding positioning disk 33 is mounted on the base 31 through hinge swinging, and the swinging axis is perpendicular to the axis of the hinge seat 32. The unfolding positioning disk 33 is provided with a plurality of positioning grooves 33a around the swinging axis of the hinge seat 32 as a reference. The position of each positioning groove 33a represents a different unfolding amplitude. The nozzle 21 is provided with a positioning beam 24 along a direction parallel to the swinging axis of the hinge seat 32. After the nozzle 21 swinging on the hinge seat 32 swings to a desired position, the unfolding positioning disk 33 that is unfolded outward is swung to a vertical position, so that the positioning beam 24 passes through the positioning groove 33a on the unfolding positioning disk 33 to stabilize the amplitude and position of the swinging and unfolding of the nozzle 21, and a thread is provided on the positioning beam 24. The positioning beam 24 that passes through the positioning groove 33a is fixed by locking the positioning beam 24 with a nut.

[0027] At the same time, an opening is provided at the top of the electric control cabinet 1 and the connecting pipe 23 passes through the opening to enter the electric control cabinet 1. The base 31 is also provided with a through hole and is coaxially connected to the opening. The base 31 rotates through the connection between the two holes. Subsequently, an arc-shaped turning groove 1a is provided at the top of the electric control cabinet 1 with the axis of the opening as the center axis. Bolts are provided on the base 31 to pass through the turning groove 1a and nuts and bolts are provided under the turning groove 1a to fix the swing amplitude and position of the base 31. It is known to those skilled in the art that the opening and the turning groove 1a are both closed connections, such as installing a waterproof pad or a waterproof cover to isolate the opening from the inside of the electric control cabinet 1.

[0028] In the specific implementation, the nozzle 21 on the back of the electric control cabinet 1 is unfolded upward, and the nozzle 21 is unfolded and swung through the hinge seat 32, and then the electric control cabinet 1 is installed to the required position, so that the nozzle 22 of the nozzle 21 is roughly pointed to the direction of the capacitance and reactance of the substation equipment, and then the power distribution cabinet is fixed on the shelf so that it is fixed in the position of the substation design. At this time, the base 31 is rotated to point the nozzle 22 to the direction of the substation equipment, and then the nozzle 21 is swung up and down to aim the nozzle 22 at the main part with a large fire hazard, and the unfolded unfolding positioning plate 33 is swung to a vertical position, so that the positioning beam 24 passes through the positioning groove 33a on the unfolding positioning plate 33 to stabilize the amplitude and position of the nozzle 21 swinging and unfolding, and then the nozzle 21 is fixed by locking the nut on the positioning beam 24;

[0029] When the substation equipment catches fire, the electric control cabinet 1 controls, or the upper computer connected to the electric control cabinet 1 controls the heating wire to generate heat, and the heat generated stimulates the solid-gas conversion agent to react and produce gas, thereby breaking through the aluminum film and driving the fire extinguishing medium to be sprayed from the nozzle 22 in the nozzle 21 to the fire area, so as to extinguish the fire in time.

[0030] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
