Abstract
The utility model discloses a kind of energy-saving device of elevator, including elevator frequency converter, control device and the super capacitor being connected on power supply；Super capacitor is connected in parallel on elevator frequency converter；Control device is connected with super capacitor, the connection branch road for turning on super capacitor when the car of elevator is run downwards relative to counterweight, is super capacitor charging；When the car of elevator is run up relative to counterweight, control device control super capacitor first discharges to be run up for car, and when super capacitor, which discharges, to be completed, control device is connected elevator frequency converter and powered for the operation of car.The electric capacity that the super capacitor is the DC D/C powers modular converter being connected in parallel on elevator frequency converter and is connected on DC D/C power modular converters.The energy-saving device of elevator can the effectively economize on electricity 30~40% in the case where maintaining elevator normal running (operation) conditions.
Description
Technical field
The utility model is related to a kind of energy-saving device of elevator.
Background technology
Fig. 1 gives existing elevator supply structure diagram, when car is run up relative to counterweight, and motor drives car
Motion upwards, when elevator is run downwards relative to counterweight, a large amount of electric energy lose on dead resistance, cause energy charge.Though
So also there is the series-connection charge-discharge circuit on dead resistance at present, to reduce the technical scheme of energy consumption, but effect is not protruded.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of energy-saving device of elevator, elevator can maintained normal
Effectively economize on electricity 30~40% under service condition.
A kind of energy-saving device of elevator, including elevator frequency converter, control device and the super capacitor being connected on power supply；It is described
Super capacitor is connected in parallel on the elevator frequency converter；The control device is connected with super capacitor, for the car phase in elevator
The connection branch road of the super capacitor is turned on during operation downward for counterweight, is the super capacitor charging；When the elevator
When car is run up relative to counterweight, the control device control super capacitor first discharges to be run up for car, when
When the super capacitor electric discharge can not meet elevator operation, it is the car that the control device, which connects the elevator frequency converter,
Operation power supply.
The super capacitor is the DC-DC power source conversion module being connected in parallel on the elevator frequency converter and is connected to described
Electric capacity in DC-DC power source conversion module.
The energy-saving device of elevator is simple in construction, it is only necessary to which it is that can be achieved to carry out simple refit to existing elevator, can maintain electricity
Effectively economize on electricity 30~40% under terraced normal running (operation) conditions.
Brief description of the drawings
Fig. 1 is existing elevator supply structure diagram；
The structure diagram for the energy-saving device of elevator that Fig. 2 the utility model is provided.
Embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in figure 1, a kind of energy-saving device of elevator, including elevator frequency converter, the control device and super being connected on power supply
Level electric capacity；Super capacitor is connected in parallel on elevator frequency converter；Control device is connected with super capacitor, relative for the car in elevator
The connection branch road of super capacitor is turned on when counterweight is run downwards, is super capacitor charging；When the car of elevator is relative to counterweight
When running up, control device control super capacitor first discharges to be run up for car, when super capacitor electric discharge can not expire
During sufficient elevator operation, control device is connected elevator frequency converter and powered for the operation of car.The super capacitor becomes to be connected in parallel on elevator
DC-DC power source conversion module on frequency device and the electric capacity being connected in DC-DC power source conversion module.
The energy-saving device of elevator is simple in construction, it is only necessary to which it is that can be achieved to carry out simple refit to existing elevator, can maintain electricity
Effectively economize on electricity 30~40% under terraced normal running (operation) conditions.
