Abstract
The utility model relates to an explosion-proof motor. The explosion-proof motor comprises a motor shell; a junction box is arranged outside the motor shell; a wiring terminal is arranged in the junction box; a refrigerator is arranged in the junction box; the wiring terminal is connected with the refrigerator; an air extracting device and an air charging system are arranged outside the motor shell; the air extracting device and the air charging system are connected with the junction box through ventilation pipes; the air extracting device is used for extracting the air in the junction box; and the air charging device is used for charging nitrogen in the junction box. According to the explosion-proof motor provided by the utility model, as the refrigerator works, the temperature in the junction box is reduced, the lead is hard to burn at too high temperature, the motor is prevented from exposing; the running stability of the motor is increased, and the potential safety hazard is eliminated; as the air extracting device extracts the air in the junction box, the air charging device charges the nitrogen in the junction box, even if a lead is connected with the wiring terminal to emerge spark, the motor is hard to expose, thus, the running stability of the motor is further increased, and the potential safety hazard is further eliminated.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of fire-proof motor, belongs to technical field of motors.
Background technology
Motor be a kind of with electric energy efficiently convert to machinery equipment, most industrial equipment all is equipped with motor and makes driving arrangement.The housing of motor is typically provided with terminal box outward, is provided with binding post in the terminal box, is used for linking to each other with the power lead of outside.Existing motor is when running, and outside power lead and binding post connecting place often generate heat, and cause wire to burn because of excess Temperature, causes the motor blast, has caused potential safety hazard; While is along with power of motor of today continues to increase, so that the also constantly increase of the output current of power supply, therefore when motor operates; the outside power lead electric spark of often can emerging that links to each other with binding post; if there is fuel gas in the terminal box, can cause the motor blast, caused potential safety hazard.
The utility model content
The utility model purpose is that a kind of stable, fire-proof motor of having eliminated potential safety hazard is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fire-proof motor, comprise electric machine casing, and described electric machine casing is provided with terminal box outward, is provided with binding post in the described terminal box, is provided with refrigerator in the described terminal box; Described binding post links to each other with refrigerator; Described electric machine casing also is provided with air extractor and aerating device outward; Described air extractor links to each other with terminal box by breather pipe with aerating device; Described air extractor is used for the air in the terminal box is extracted out, and described aerating device is used for being filled with nitrogen in terminal box.
Preferably, described air extractor and aerating device lay respectively at the both sides of terminal box.
Preferably, described air extractor links to each other with electric machine casing by support with aerating device.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Fire-proof motor of the present utility model, because be provided with refrigerator in the terminal box, binding post links to each other with refrigerator, when the power lead of outside and binding post are connected to motor and power, also power to refrigerator simultaneously, therefore motor is when running, and refrigerator is also worked simultaneously, has reduced the temperature in the terminal box, so that wire is difficult for burning because of excess Temperature, avoid the motor blast, increased the stability of motor operation, eliminated potential safety hazard; Because electric machine casing also is provided with air extractor and aerating device outward, air extractor links to each other with terminal box by breather pipe with aerating device, air extractor is extracted the air in the terminal box out, aerating device is filled with nitrogen in terminal box, the electric spark of emerging even wire links to each other with binding post, also be difficult for causing the motor blast, further increased the stability of motor operation, eliminated potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of fire-proof motor of the present utility model;
Wherein: 1, electric machine casing; 2, terminal box; 3, binding post; 4, refrigerator; 5, air extractor; 6, aerating device; 7, support; 8, breather pipe.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of fire-proof motor as shown in Figure 1 comprises electric machine casing 1, is provided with terminal box 2 outside the described electric machine casing 1, is provided with binding post 3 in the described terminal box 2, is provided with refrigerator 4 in the described terminal box 3; Described binding post 3 links to each other with refrigerator 4; Described electric machine casing 1 outer air extractor 5 and the aerating device 6 of also being provided with; Described air extractor 5 links to each other with electric machine casing by support 7 with aerating device 6; Described air extractor 5 links to each other with terminal box 2 by breather pipe 8 with aerating device 6; Described air extractor 5 and aerating device 6 lay respectively at the both sides of terminal box 2; Described air extractor 5 is used for the air in the terminal box 2 is extracted out, and described aerating device 6 is used for being filled with nitrogen in terminal box 2.
During use, the power lead of outside is linked to each other with binding post 3, during the motor power supply, also to refrigerator 4 power supplies, motor is when running simultaneously, refrigerator 4 is also worked simultaneously, reduce the temperature in the terminal box 2, so that wire is difficult for burning because of excess Temperature, avoided the motor blast, increase the stability of motor operation, eliminated potential safety hazard; Open simultaneously air extractor 5 and aerating device 6, air extractor 5 is extracted the air in the terminal box 2 out, aerating device 6 is filled with nitrogen in terminal box 2, the electric spark of emerging even wire links to each other with binding post, because the air content of terminal box 2 is less, great majority are nitrogen, therefore are difficult for causing the motor blast, further increase the stability of motor operation, eliminated potential safety hazard.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
