Abstract
The utility model discloses a kind of natural ventilation type distribution low-voltage switch protection case, comprise casing and case lid, the top of described casing is the double-decker separated by dividing plate, and upper strata is air blanketing, and four sidewalls all offer some ventilation holes, the height of described air blanketing is greater than 20mm; Described case lid is eaves formula structure, and cornice position is lower than the position of described air blanketing.The utility model adopts natural draft radiating mode to dispel the heat to casing, and the air blanketing on casing top is guaranteed to keep radiating effect at nature by under condition; Case lid is eaves formula structure simultaneously, and the ventilating opening on air blanketing sidewall, lower than the position of air blanketing, is blocked by case lid in cornice position, guarantees that rainwater can not be undertaken, in casing, improve the protective capacities of low tension switch guard box by ventilating opening.
Description
Technical field
The utility model relates to a kind of Allocation transformer auxiliary products, specifically a kind of outdoor distribution low-voltage switch protection case.
Background technology
Outdoor distribution low-voltage switch protection case is a kind of novel power supply corollary equipment; be applicable to city net and Transformers for Rural Networks; in rated voltage 380V and following distribution system thereof; be generally the casing be made up of stainless steel material or SMC composite material; be used for replacing the product of registering one's residence of former built on stilts incoming type; electric equipment and cable investment can be saved, to realize the optimization of electrical power trans mission/distribution system, there is very strong flexibility and reliability.
Outdoor Allocation transformer low tension switch guard box is when designing, and performance of ventilating is a very important index, and the temperature inside the box of low tension switch guard box is too high, and the useful life of its inner member and performance can be had a strong impact on.In order to ensure draught capacity, have in prior art and casing and lid section are improved, add ventilation hole; but; although this scheme improves the draught capacity of low tension switch guard box, intensity and the rainproof ability of casing are all subject to great impact, can not meet design standard.
Also have in addition and arrange air blast in the bottom of casing, improve air velocity by air blast, although this design effect is fine, shortcoming also clearly, not only increases cost, wastes energy, and also can produce noise, affect the normal life of people.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides the distribution low-voltage switch protection case that a kind of protective capacities is strong, ventilation effect is good.
Technical scheme: natural ventilation type distribution low-voltage switch protection case described in the utility model, comprise casing and case lid, the top of described casing is the double-decker separated by dividing plate, and upper strata is air blanketing, and four sidewalls all offer some ventilation holes, the height of described air blanketing is greater than 20mm; Described case lid is eaves formula structure, and cornice position is lower than the position of described air blanketing.
In the utility model, casing top is provided with air blanketing, ventilation hole on air blanketing sidewall communicates with the eaves wall of case lid, hot-air in casing is outwards distributed by the ventilation hole at casing top and cornice, natural draft is relied on to reach heat radiation object, because the height of air blanketing is greater than 20mm, ensure that radiating effect; In addition, case lid is eaves formula structure, and cornice position, lower than the position of described air blanketing, can ensure can not be immersed by rainwater in casing, improves the protective capacities of low tension switch guard box.
The utility model technical scheme is further preferably that the base plate of described casing and dividing plate are provided with ventilation hole, and forms air channel in described casing.Form air channel in casing, improve the integral heat sink effect of casing.
Preferably, the slope of roof of described case lid is greater than 5%.Case lid is eaves formula structure, and the slope of roof is greater than 5%, and case lid top can not produce ponding.
Preferably, the binding post position of described case lid upper end is also provided with rainproof porcelain patticoat, and described rainproof porcelain patticoat is wrapped in the outside of described binding post, and bottom is connected with described case lid, and junction arranges proof mechanism of water.
Preferably, the sidewall of described casing and case lid adopt SMC material or stainless-steel sheet to make, and described box bottom adopts epoxide resin material to make.
Beneficial effect: (1) the utility model adopts natural draft radiating mode to dispel the heat to casing, the air blanketing on casing top is guaranteed to keep radiating effect at nature by under condition; Case lid is eaves formula structure simultaneously, and the ventilating opening on air blanketing sidewall, lower than the position of air blanketing, is blocked by case lid in cornice position, guarantees that rainwater can not be undertaken, in casing, improve the protective capacities of low tension switch guard box by ventilating opening; (2) in the utility model, the slope of roof of case lid is greater than 5%, can guarantee that case lid top can not produce ponding, meet rainwater protection requirements; (3) in the utility model, binding post position is provided with rainproof porcelain patticoat, and proof mechanism of water is set at rainproof porcelain patticoat and case lid link position, can guarantee that casing can not be immersed by rainwater, improve protective capacities further; (4) in the utility model, the sidewall of casing and case lid adopt SMC material or stainless-steel sheet to make, and box bottom adopts epoxide resin material to make, and guaranteeing the intensity of casing simultaneously, improve the radiating effect in casing.
