Based on the structure, the invention provides a structural schematic diagram of the 10kV switch cabinet with the explosion-proof heat dissipation function.
The following is a detailed description of an embodiment of the 10kV switch cabinet with explosion-proof and heat dissipation functions.
Referring to fig. 1-3, this embodiment provides an attached cabinet of a 10kV switchgear with an explosion-proof heat dissipation function, including: a main housing and an isolation compartment 4.
In this embodiment, the main box is fixed on 10kV cubical switchboard, and the upper portion of main box is equipped with air intake 5, and the side upper portion of main box and 10kV cubical switchboard contact one side is equipped with first air exchange mouth 7.
It should be noted that the main box body is a main body structure of the auxiliary cabinet, and mainly bears the damage of shock waves and fragments generated by the heating explosion of the 10kV switch cabinet of the transformer substation. The main box body can be set to be a flat rectangular structure, and is formed by assembling a plurality of sealing plates. The main box body is a back surface on the surface contacted with the 10kV switch cabinet, the surface opposite to the back surface is a front surface (namely a front middle door sealing plate 1), and two sides are side surfaces (namely a front right door sealing plate 6).
In order to ensure the overall structural strength of the main box body and prevent tiny fragments from splashing out through the main box body, the air inlet 5 and the first air exchange port 7 are arranged in a staggered manner. The first air exchange port 7 needs to be tightly attached to the 10kV switch cabinet, namely, is arranged on the side surface (namely, the back surface) of the main box body, which is in contact with the 10kV switch cabinet, so that the air inlet 5 is arranged on the side surface of the main box body. The first air exchange port 7 is provided with a filter screen which is used as a gas exchange channel, can prevent dust, small animals and foreign matters from entering to cause equipment short circuit, and is fixed by screws, detachable, replaceable and clean.
The area of the first air exchange port 7 is too large, which leads to the decrease of structural strength, and too small, which affects the heat dissipation effect, so that the heat dissipation device should be specifically set according to the overall structural strength and safety requirements. The air inlet 5 can be provided with a wind shield to inhibit dust from blocking wind. Can ensure that wind blows into the cabinet softly, prevent dust accumulation in the cabinet, prevent that condensation water congeals the cold dew and causes creepage pollution flashover and reduces the problem of cabinet internal insulation level. The height position of the air inlet 5 is matched with the height position of the first air exchange port 7.
In addition, as shown in fig. 4-5, a plurality of (preferably 8) through holes 9 are symmetrically arranged at the top of the auxiliary cabinet in parallel, and the through holes 9 are filled by plastic screws. The pressure release device is used for releasing the pressure of the auxiliary cabinet when the air pressure is too high due to the fact that the heat dissipation fan does not rotate or overload operation is carried out in the switch cabinet. Because the effect of hot air, the top pressure of the auxiliary cabinet is the highest at this moment, and the auxiliary cabinet is used as the weakest part of the whole device (namely, the part with the most obvious feeling on the rising of air pressure), when the pressure suddenly increases, the plastic screw can spring up, so that the conditions of cabinet door flushing and high-speed impact of parts in the cabinet are avoided. The safety of the person is ensured, the pressure relief effect is achieved, when the pressure of the attached cabinet is overlarge, the plastic screw automatically bounces off to release the pressure, and the pressure relief protection device is used.
In this embodiment, the isolation cabin 4 is fixed at the lower part of the main box, the side surface of the isolation cabin 4, which contacts with the 10kV switch cabinet, is provided with a second air exchange port 8, and other side surfaces of the isolation cabin 4 are provided with air outlets 3.
The isolation chamber 4 may be provided as a main case, and may be formed as a flat rectangular body. The whole size is set according to the actual situation. One side (namely the back side) of the isolation cabin 4, which is close to the 10kV switch cabinet, is provided with a second air exchange port 8, and the other side surfaces are provided with air outlets 3.
The compartment 4 serves as a separate space compared to the main housing, mainly for the evacuation of hot air from the switchgear. Similarly, in order to achieve both heat dissipation efficiency and prevention of splashing of the chips, the second air exchanging port 8 is also provided with a filter screen and is provided in a long strip shape. The filter screen on other side surfaces can be larger, which is convenient for discharging hot air in the cabinet.
And the air outlet 3 (namely a filter screen at the periphery of the isolation cabin) is designed at the lower side of the rear auxiliary cabinet, so that air can be discharged more quickly and timely, and air is prevented from accumulating and flowing back into the switch cabinet. The bottom air outlet 3 is provided with an independent isolation cabin and a rear attached cabinet to separate, so that inhaled air is guaranteed to flow into the switch cabinet and is isolated from air exhausted from the switch cabinet, cold and hot air convection is avoided, cooling efficiency is improved, and the safety of field personnel below legs is protected due to the fact that the lower air outlet is provided with an isolation layer when the switch cabinet explodes.
Furthermore, the main box body and the isolation cabin 4 are both made of double-layer aluminum zinc coated plates, and the material has the advantages of no hysteresis loss, corrosion resistance, rust resistance, excellent heat resistance, oxidation resistance, static resistance, good adhesive force, high mechanical strength, good crack resistance, water resistance, wear resistance, oil resistance, good insulating property and good dust suppression rate.
And the outside (i.e., the front) of the main casing is also provided with an observation window 2. The observation window 2 adopts double-layer explosion-proof glass, steel wire mesh is clamped between the glass, the glass material is polycarbonate, and the observation window 2 consists of a plurality of hollow entities which are alternately regular hexagon honeycomb-shaped with the same size. When encountering the cubical switchboard short-circuit explosion and strike, polycarbonate can not broken, and the steel wire mesh can block the piece impact force, and the observation window that regular hexagon cellular constitutes stability is strong, and the pulling force is strong, can not appear the fracture condition.
In addition, can also set up electrified display device in the cabinet rear side that attaches, make things convenient for the inspection personnel to look over, electrified display device wireless connection backstage terminal, when breaking down, backstage terminal acousto-optic display.
