Abstract

The invention provides a power supply unit for standby power auto-switching devices of transformer substations. A display screen and control buttons are arranged in the front of a case. Standby power auto-switching device components, a charging circuit and a switching relay circuit are arranged in the case, and the standby power auto-switching device components and a power circuit of each circuit are connected with a charging source and a charger; and a direct-current power cord is connected with a relay and a resistor, and one of the circuits is provided with a wiring terminal. An inter-wire switch is connected between wires of a standby power auto-switching device power cord, and the standby power auto-switching device power cord is connected with a power-on switch. According to the invention, the running of the standby power auto-switching device components and the circuits is driven by using a direct-current, and the standby power auto-switching device power cord is switched on and off through the relay so as to supply power for an electric transmission line. The power supply unit disclosed by the invention has the characteristics of clear control display, easiness in use, and rapid response speed. The power supply unit is suitable to be applied to a standby power auto-switching device for replenishing power after an electric transmission line is powered-off.

Description

A kind of transformer substation spare power automatic switching electric supply installation
Technical field
What the present invention relates to is the equipment of field of power transmission, specifically a kind of transformer substation spare power automatic switching electric supply installation.
Background technology
The prepared auto restart control device refers in transformer substation system, and when outage occured main connecting line, contact device automatic processing circuit for subsequent use guaranteed the operation of electrical network normal power supply with this.Along with the carrying out of the construction retrofit work of building intelligent grid and unattended substation, the development of electric integrated automatic technology, great variation has appearred in the implementation of prepared auto restart.Add that the devices such as microcomputer type relay protection and PLC are able to extensive use in the power automation field; the logic of prepared auto restart and be improved with comparing in the past in the implementation method of present stage, a kind of overall power distribution controller with novel intelligent prepared auto restart function is widely used in electrical network.But the shortcoming of existence is that backup auto-activating device can't be enabled, and greatly reduce system's security of operation when a certain element of transformer station has a power failure.
