Abstract
The utility model is a kind of high-protection level frequency-conversion drive apparatus, and the terminal block being connected with variable frequency drives is installed on the sidewall of cabinet, and the cable fixed cover that is positioned at cabinet outside is installed on terminal block; Also comprise and be arranged on the upper cover on cabinet and be arranged on the control box covering, control box, upper cover and cabinet surround closed cavity.Variable frequency drives is placed among seal chamber and has solved heat dissipation problem, has high-grade protective capacities, and degree of protection can reach IP66, significantly reduces, and improved the useful life of variable frequency drives for failure rate under the working conditions such as moist or many dust.In addition, because this device has higher protective capacities, therefore do not need to set up in addition electric panel room or rack, significantly minimizing equipment takes up an area, and reduces wiring cost.
Description
Technical field
The utility model relates to a kind of frequency-conversion drive apparatus, is specifically related to a kind of high-protection level frequency-conversion drive apparatus that can normally work under moist or many dust working condition.
Background technology
Existing frequency-conversion drive apparatus does not generally have suitable protection mechanism, and when use, in exposed state, under the adverse circumstances such as humidity or dust, operational failure rate is very high, and affects the useful life of variable frequency drives; On the other hand, existing frequency-conversion drive apparatus generally need to arrange supporting electric panel room or rack, and ubiquity floor space is large, the defect that wiring cost is high.
Utility model content
Technical problem to be solved in the utility model is, a kind of high-protection level frequency-conversion drive apparatus is provided, variable frequency drives is placed among closed cavity, and by control box integrated installation to described closed cavity shell.
The technical solution of the utility model is as follows:
High-protection level frequency-conversion drive apparatus, comprises the cabinet that is built-in with variable frequency drives, it is characterized in that: the terminal block being connected with variable frequency drives is installed on the sidewall of cabinet, and the cable fixed cover that is positioned at cabinet outside is installed on terminal block; Also comprise and be arranged on the upper cover on cabinet and be arranged on the control box covering, control box, upper cover and cabinet surround closed cavity.
On the sidewall of cabinet, offer louvre; Also comprise the radiating fin that the blower fan that is built in cabinet and root and cabinet inwall are connected.
Good effect of the present utility model is:
The first, variable frequency drives of the present utility model is placed among seal chamber and has solved heat dissipation problem, there is high-grade protective capacities, degree of protection can reach IP66, significantly reduces, and improved the useful life of variable frequency drives for failure rate under the working conditions such as moist or many dust.In addition, because this device has higher protective capacities, therefore do not need to set up in addition electric panel room or rack, significantly minimizing equipment takes up an area, and reduces wiring cost.
The second, the utility model control box is arranged on and is covered by screw fastening, and upper cover is arranged on cabinet by screw fastening, and cable fixed cover is arranged on cabinet outside.There is installation, use simply the feature of convenient disassembly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Describe the utility model in detail below in conjunction with the drawings and specific embodiments.
With reference to figure 1, embodiment of the present utility model comprises the cabinet 4 that is built-in with variable frequency drives and upper end open, offers louvre 6 on the sidewall of cabinet 4.The terminal block being connected with variable frequency drives is also installed on the sidewall of cabinet 4, and the cable fixed cover 5 that is positioned at cabinet 4 outsides is installed on terminal block, client accesses variable frequency drives by cable fixed cover 5 by cable.
Embodiment of the present utility model also comprises by trip bolt 1 and is arranged on the upper cover 3 of cabinet 4 upper port and is arranged on the control box 2 on upper cover 3 by trip bolt 1, is provided with button, display screen and indicator light on control box 2.Control box 2, upper cover 3 and cabinet 4 form closed cavity.
Embodiment of the present utility model also comprises the radiating fin that the blower fan that is built in cabinet 4 and root and cabinet 4 inwalls are connected.Heat when blower fan work, variable frequency drives being produced is discharged by louvre 6, to ensure variable frequency drives reliably working.Louvre 6 generally has two, and they offer respectively on two sidewalls that cabinet 4 is relative, and one for air intake, and another is for air-out.
