Description

I

The invention relates to a current-collecting electrical vehicles, namely to devices driven by magnetic means.

A device for power supply of a vehicle is known, which contains a supply line connected to a current collector through contact elements of intermediate contacts arranged in a housing and interacting with a partition made with alternating conducting and insulating sections. Sliding contacts located above the partition M are connected.

However, during the operation of a known device, there is a danger of electric injury.

The purpose of the invention. is an increase in electrical safety.

The goal is achieved by the fact that the sliding contacts are made in the form of permanent magnets, and

The contact elements of the intermediate contacts are made of elastic magnetic material.

FIG. 1 schematically shows a two-wire device with magnets removed from a septum; in fig. 2 - device in the position of transfer of energy from the power line; in fig. 3 section of the device; in fig. k - seed A-A in FIG. 3 (in the zone of one intermediate contact)

The vehicle power supply device comprises alternating conductive and insulating portions.

Claims (1)

The housings are located 6 separator 6, which fixes them at a distance, excluding an open circuit in the transfer of current and short circuit. A consumer 7 with a current collector 8 with sliding contacts 9. made in the form of permanent magnets is mounted above the pe3 partition. The power supply device may be stationary or portable. The partition 1 can be made in the form of a well-known profile or ceiling on the installation site of the device, for example, the floor 10 (FIG. 3 and), and its current-conducting areas in the form of its segments, connected by insulating sections, and also in the form of well-known passages contacts in insulating material. In case of using for making the partition 1, shells unstable to shape retaining, for example, rubber-fabric sleeves, maintaining the internal cavity of the device in a form sufficient for free movement of the intermediate contact, create an overpressure in this cavity by known means. This means, in necessary cases, is used to protect against moisture penetration and contamination through microcracks and as a device for depressurization (damage to the septum) of the device. With equipment in hazardous and fire hazardous locations, the device with a part of the current collector is placed under water, for example, in a channel filled with water. The reliability of the movement of the magnets and intermediate contacts is provided by any well-known means. The device works as follows. The consumer lowers the current collector B on the partition 1, while the sliding contact is connected to at least one conductive part of the partition. Under the action of magnetic fields, the body k of the intermediate contacts rises up to the stop into the partition 1. In this case, the contact elements 5 form a closed circuit between the contact wires 2 and 3 with the conductive sections of the partition 1, the sliding contacts 9 and the current collector 8. When the vehicle moves along the partition Magnetic sliding contacts carry along the bodies of intermediate contacts with contact elements 5, which is how the electric power is transferred to the consumer through successive contacts. in motion electrically conductive wall portion. When lifting the current collector 8 or its withdrawal from the partition wall of the case of intermediate contacts C, together with the contact elements 5 are lowered. As a result of this, the conductive partitions of the partition are disconnected from the contact wires. The use of the proposed vehicle power supply device improves the safety of the device. Claims An apparatus for vehicle power supply comprising a supply line connected to a current collector through contact elements of intermediate contacts arranged in a housing and interacting with a partition made with alternating conducting and insulating portions connected with sliding partitions located above the partition , characterized in that, in order to increase electrical safety, the sliding contacts are made in the form of permanent magnets, and the contact elements are intermediate These contacts are made of elastic magnetic material.
