Abstract
The utility model aims to provide a constant humidity switch cabinet, can maintain constant humidity in the switch cabinet and guarantees normal work of electric module units in the switch cabinet. The constant humidity switch cabinet comprises a switch cabinet body which is internally provided with a humidity sensor, a side wall of the switch cabinet body is provided with an air inlet and an air outlet, an outer portion of the switch cabinet is provided with a humidity regulator, the humidity regulator is a dehumidifier and a humidifier connected in parallel through pipeline, the dehumidifier and the humidifier are respectively connected with the humidity sensor, and the air outlet, the humidity regulator and the air inlet are connected in order though pipeline. The constant humidity switch cabinet has a simple structure, can automatically carry out dehumidification or humidification of the air in the switch cabinet, maintains constant humidity of the switch cabinet and facilitates to guarantee normal work of electric module units in the switch cabinet.
Description
Technical field
The utility model belongs to technical field of electricity, specially refers to a kind of switch cubicle.
Background technology
The electrical module unit of inside switch cabinet the time need to keep moisture stable in work, easily causes short circuit or electronic device corrosion if humidity is too high, and humidity is crossed the low electric arc that easily produces.Traditional switch cubicle is not considered the stabilizing measures of humidity, therefore can only pass through the residing indoor environment humidity of control switch cabinet, comes the humidity in the control switch cabinet, has greatly improved cost, nor has been applicable to outdoor switch cabinet.
The utility model content
The purpose of this utility model is to propose a kind of constant humidity switch cubicle, and the humidity in can the maintained switch cabinet is constant, guarantees that the electrical module unit in the switch cubicle keeps normal operation.
Constant humidity switch cubicle of the present utility model comprises that inside is provided with the switch cubicle body of humidity sensor, the sidewall of described switch cubicle body is provided with air inlet and gas outlet, the outer setting of described switch cubicle has humidistat, described humidistat is dehumidifier and humidifier by the pipeline parallel connection, and described dehumidifier, humidifier link to each other with humidity sensor respectively; Described gas outlet, humidistat and air inlet link to each other successively by pipeline.
When work, humidistat receives the data of humidity sensor, and decides startup dehumidifier or humidifier work according to the humidity situation in the current switch cubicle, when the humidity in the switch cubicle is too high, starts dehumidifier work; Cross when low when the humidity in the switch cubicle, start humidifier work.When dehumidifier or humidifier work, its built-in fans drive air-flow flows to dehumidifier or humidifier through the gas outlet in switch cubicle, behind dehumidifying or humidification, flow in the switch cubicle through air inlet again, thereby the humidity in the by-pass cock cabinet makes its maintenance constant.
Further, described air inlet is arranged at the bottom of switch cubicle, and described gas outlet is arranged at the top of switch cubicle, can guarantee that so not only the overall humidity in the switch cubicle is stable, can also avoid the air that humidifier flows out to be sprayed directly on on the electrical appliance module unit, cause short circuit.
Constant humidity switch cabinet structure of the present utility model is simple, can automatically dehumidify or humidification to the air in the switch cubicle, makes the humidity in the switch cubicle keep constant, and the electrical module unit that is conducive in the switch cubicle keeps normal operation.
Description of drawings
Fig. 1 is the structural representation of constant humidity switch cubicle of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the constant humidity switch cubicle of the present embodiment comprises that inside is provided with the switch cubicle body 1 of humidity sensor, the sidewall of described switch cubicle body 1 is provided with air inlet 2 and gas outlet 3, the outer setting of switch cubicle 1 has humidistat, described humidistat is dehumidifier 4 and humidifier 5 by the pipeline parallel connection, and described dehumidifier 4, humidifier 5 link to each other with humidity sensor respectively; Described gas outlet 3, humidistat and air inlet 2 are by pipeline link to each other successively (humidity sensor not shown in FIG.).
When work, humidistat receives the data of humidity sensor, and decides startup dehumidifier 4 or humidifier 5 work according to the humidity situation in the current switch cubicle body 1, when the humidity in the switch cubicle body 1 is too high, starts dehumidifier 4 work; Cross when low when the humidity in the switch cubicle body 1, start humidifier 5 work.When dehumidifier 4 or humidifier 5 work, its built-in fans drive air-flow flows to dehumidifier 4 or humidifier 5 through gas outlet 3 from switch cubicle body 1 is interior, behind dehumidifying or humidification, flow in the switch cubicle body 1 through air inlet 3 again, thereby the humidity in the by-pass cock cabinet body 1 makes its maintenance constant.
Further, air inlet 2 is arranged at the bottom of switch cubicle body 1, and gas outlet 3 is arranged at the top of switch cubicle body 1, can guarantee that so not only the overall humidity in the switch cubicle body 1 is stable, can also avoid the air that humidifier 5 flows out to be sprayed directly on on the electrical appliance module unit, cause short circuit.
Claims (2)
1. constant humidity switch cubicle, comprise that inside is provided with the switch cubicle body of humidity sensor, the sidewall that it is characterized in that described switch cubicle body is provided with air inlet and gas outlet, the outer setting of described switch cubicle has humidistat, described humidistat is dehumidifier and humidifier by the pipeline parallel connection, and described dehumidifier, humidifier link to each other with humidity sensor respectively; Described gas outlet, humidistat and air inlet link to each other successively by pipeline.
2. constant humidity switch cubicle according to claim 1 is characterized in that described air inlet is arranged at the bottom of switch cubicle, and described gas outlet is arranged at the top of switch cubicle.
