The utility model is capable of making the energy consumption produced in the braking process of the elevator feeding back to the wire fence, saving energy and improving the environment, but no need increase cost and n o polluting the wire fence and interfering other equipments.
Description
Technical field:
The utility model relates to the elevator control cabinet structure, particularly be a kind of energy-saving elevator control cabinet.
Background technology:
Existing elevator all has independently control system, and the carrier of control system is exactly an elevator control cabinet.Include the main control system plate in the elevator control cabinet, elevator special converter, and various contactor and the relay that plays safety, detection effect.
What the mode of braking of present most of elevator producer all adopted is the resistance energy-consumption braking, the energy that just elevator is opened the braking generation is released on the brake resistance, be discharged in the machine room in the mode of heat energy then and slattern, the heat that produces in this process not only can cause the rising of ambient temperature, but also can influence the operate as normal of other control panels.And lower the temperature for the ambient temperature that ensures machine room needs air-conditioning, will increase cost and extra energy consumption like this; And the process that regenerative electric energy is released on the brake resistance also can produce noise and electric radiation, thereby environment and network system are polluted, and especially uses the place of the elevator of high speed that high-power electric drags, heavy amount, and this situation is just more outstanding.
Summary of the invention:
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of can feed back to electrical network with the heat on the brake resistance, carries out reusable energy-saving elevator control cabinet.
The utility model is achieved through the following technical solutions: a kind of elevator control cabinet, by cabinet, be arranged on the main control microcomputer plate in the cabinet, primary transducer and contactor and relay are formed, wherein said primary transducer one end is connected with the main control microcomputer plate, the other end is connected with an energy feedback frequency converter, and described energy feedback inverter output terminal is connected with the control signal binding post.
The energy that produces when wherein said energy feedback frequency converter is used for primary transducer braked flows to electrical network by the control signal binding post.
Wherein said primary transducer is connected with external motor by the main control microcomputer plate.
The utility model passes through to connect an energy source feedback frequency converter in primary transducer, thereby realizes that the part energy consumption that elevator is produced in braking procedure feeds back to electrical network, and then reaches the purpose of energy-conservation and environmental protection.
Description of drawings:
Fig. 1 is the utility model elevator cabinet schematic perspective view.
Fig. 2 is the utility model elevator cabinet internal structure schematic diagram.
Identifier declaration among the figure: cabinet 1, primary transducer 2, energy feedback frequency converter 3, contactor 4, main control microcomputer plate 5, relay 6, control signal binding post 7.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As Fig. 1～shown in Figure 2, the utility model provides a kind of elevator control cabinet, by cabinet 1, be arranged on the main control microcomputer plate 5 in the cabinet, primary transducer 2 and contactor 4 and relay 6 are formed, wherein said primary transducer 2 one ends are connected with main control microcomputer plate 5, and the other end is connected with an energy feedback frequency converter 3, and described energy feedback frequency converter 3 outputs are connected with control signal binding post 7.
The main effect of primary transducer 2 is the frequencies by the change alternating current, energy-conservation and speed governing, and automatic control of realization and High Accuracy Control.External motor described in the utility model is the inductive ac motor, in the elevator control procedure, need to regulate the rotary speed of motor, thereby elevator is normally moved, and the rotary speed of motor is determined at the number of poles and the frequency of motor approx, because the number of poles of motor is changeless, is worth the speed of adjusting motor so be not suitable for changing this.In addition, electric machine frequency is the signal of telecommunication of motor power supply, so frequency values can resupply motor after the outside of motor is regulated, the rotary speed of motor just can be controlled freely like this.Therefore, can regulate rotating speed of motor by primary transducer 2, its relation is as follows: n=60f/p, n are synchronizing speed, and f is a supply frequency, and p is a motor pole number.As shown from the above formula, change supply frequency and then can change rotating speed, but iff changing frequency, motor will be burnt out.In order to prevent the generation of burn-down of electric motor accident, frequency converter must change voltage simultaneously when changing frequency, for example: for the rotary speed that makes motor reduces by half, the output frequency of frequency converter must change to 30Hz from 60Hz, at this moment the output voltage of frequency converter just must change to about 100V from 200V, also can produce heat in the frequency converter change frequency process in addition, and the failure rate of frequency converter raises and the rising of exponentially with temperature, raise and the decline of exponentially with temperature useful life, ambient temperature rising 10 degree, frequency converter reduces by half useful life.When frequency converter is worked, the electric current that flows through frequency converter is very big, the heat that frequency converter produces also is very large, therefore the output in primary transducer 2 is connected with an energy feedback frequency converter 3, described energy feedback frequency converter 3 carries out the energy feedback with the heat that primary transducer produces, finally return electrical network, realize reusing, thereby reach energy-conservation purpose by control signal binding post 7.
The utility model is mainly by three-phase alternating-current supply, primary transducer 2, energy feedback frequency converter 3, threephase motor, and speed encoder and control system processing unit are formed.Wherein, three-phase alternating-current supply links to each other by the input terminal of master switch with primary transducer 2, and the lead-out terminal of primary transducer 2 is connected with three-phase alternating-current motor through contactor 4 and relay 6.Primary transducer 2 input terminals link to each other with encoder by shielding conductor, realize forward and reverse operation of motor.
More than a kind of elevator control cabinet described in the utility model is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
