Description

  The present invention relates to an elevator control device that uses an electric device in which an electrolytic solution is sealed, and particularly to measures against liquid leakage of the electric device.

In recent years, elevators are becoming so-called machine room-less structures in which all devices such as hoisting machines and control panels are housed in hoistways and machine rooms are removed. This eliminates the need for a room in the machine room, which has various advantages such as increasing the degree of freedom in building design and increasing the effective building area. It has become a challenge. A general elevator control device includes a converter that rectifies AC power and converts it into DC power, and an inverter that converts DC power into AC power of variable voltage and variable frequency, and drives the motor to drive the elevator. is there. A control panel used for a control device of a machine room-less elevator often has a vertically long and thin structure.
On the other hand, even when a power failure or failure occurs, a function is often added to prevent the passenger from being trapped by driving the elevator car to the nearest floor. For example, a power storage device such as a battery or a capacitor is provided, and power is supplied from the power storage device to provide a backup power source during a power failure (see, for example, Patent Document 1). In order to make effective use of the regenerative power generated during normal operation, energy-saving elevators that store regenerative power in the power storage device and discharge from the power storage device when power is needed are also used to reduce the size of the power storage device. It has been implemented from the development of high output (for example, see Patent Document 2).

In an electric device enclosing an electrolyte solution such as a power storage device, the electrolyte solution may leak due to an excessive load or life. In addition, electrical equipment that encloses an electrolyte solution may cause a circuit fault due to the electrolyte solution reaching the terminal part of the electrical equipment when the liquid leaks depending on how the equipment is installed and installed. is there. In addition, there is a risk that a circuit short circuit may occur due to the leaked electrolyte. Further, when the electrolytic solution is a strong acid or strong alkali component, the electrolytic solution may cause deformation or deterioration of parts.
In particular, in the case of a machine room-less elevator, the placement of the power storage device can be restricted in order to mount a high-output power storage device in a space-saving space, or even to install a plurality of power storage devices. It is often mounted in various directions. When the electrolyte is leaked from a certain power storage device in such a limited space, the electrolyte may adhere to other equipment, or the electrolyte may be connected to terminals or other connections and wires There was a possibility that short circuit and ground fault might occur in the circuit of materials.

  The present invention has been made to solve the above-described problems. By taking measures against liquid leakage in an electric device enclosing an electrolytic solution, a short circuit or a ground fault of the circuit due to the leakage of the electrolytic solution does not occur. An elevator control apparatus is provided.

The elevator control device according to the present invention includes a converter that rectifies AC power and converts it into DC power, and an inverter that converts DC power into AC power of variable voltage and variable frequency, and drives the motor to drive the elevator. in those, we use electric devices enclosing an electrolyte to the electrical equipment used in the control device, the electrical device in which the electrolytic solution is enclosed, if the leakage of the electrolytic solution occurs, electrolyte other A partition plate made of an electrically insulating material that prevents the device from reaching the device is provided, and the partition plate made of an electrically insulating material has a through-hole through which the terminal portion penetrates, and when the electrolyte solution leaks, the electrolyte solution It leaks from the through hole of the partition plate .

  In the case of using an electrical device in which an electrolyte solution that may leak in a limited space is used, if the receiving device is provided on the lower side of the electrical device or between the terminals, the fluid leaks. Even so, secondary damage such as short circuit and ground fault can be prevented.

  An elevator control apparatus according to the present invention includes a converter that rectifies AC power and converts it into DC power, and an inverter that converts DC power into AC power with variable voltage and variable frequency, and drives the motor to drive the elevator. In this case, it is assumed that an electric device in which an electrolytic solution having a possibility of liquid leakage is enclosed is used as the electric device used in the control device.
