Embodiment Construction

[0047] In the present invention, it is the same as the previous examples including Figure 4 In the configuration shown, charge and discharge control of the secondary battery of the power storage device is performed. However, as described later, in the present invention, the winch is arranged in the pit of the lifting path, and the control panel with other control devices is arranged on the inner wall of the lifting path, and the machine room is not arranged on the top of the lifting path.

[0048] In the present invention, a plurality of single secondary batteries are connected in series to constitute the secondary batteries of the power storage device, so the actual installation space of the power storage device can be saved, and it can be applied to elevators without a machine room.

[0049] Hereinafter, specific embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

Abstract

A controller of an elevator in which space for mounting a power accumulating device can be saved and the controller can be applied to an elevator having no machine room. The controller has a power accumulating device arranged between DC buses connected to a converter and an inverter, and accumulating DC power from the DC buses during a regenerative operation of the elevator and supplying the DC power accumulated to the DC buses during a power operation; and a charging-discharging control for controlling charging and discharging of the power accumulating device with respect to the DC buses. The power accumulating device includes a secondary battery and a DC-DC converter for controlling charging and discharging of the secondary battery, and the secondary battery includes plural cells connected in series. The secondary battery is arranged at any one of four corners within an elevator shaft, near a rail, or near a cable within the elevator shaft.

Description

technical field [0001] The present invention relates to an energy-saving elevator control device using a secondary battery such as a nickel-hydrogen battery, a nickel-chromium battery, or a lithium-ion battery. Background technique [0002] Figure 4 This is a diagram showing the basic configuration of a control device that controls an elevator using a conventional secondary battery. exist Figure 4 Among them, 1 is a three-phase AC power supply, and 2 is a converter composed of diodes that convert the AC power output from the three-phase AC power supply 1 into DC power, and supply the DC power converted by the converter 2 to the DC bus 3. 4 is The inverter controlled by the speed control device described later to control the speed and position of the elevator converts the supplied DC power into the required AC power of variable voltage and frequency by means of the DC bus 3 and supplies it to the AC motor 5 to rotate and drive The hoist 6 of the elevator directly connected...
