Abstract

The utility model discloses an UPS (uninterrupted power supply) device for the electrical switch-on circuit of a high-voltage relay switch, wherein the power source of the electrical switch-on circuit is provided by a voltage mutual inductor; a comprehensive protection device, an electrical switch-on button and a switch-on coil are connected to the voltage mutual inductor; the control end of the switch-on coil is connected with the circuit-breaking switch of a circuit breaker; the input end of the voltage mutual inductor is connected to the low-voltage coil end of a transformer; the output end of the voltage mutual inductor is connected with an UPS; and the comprehensive protection device, the electrical switch-on button and the switch-on coil are connected in series to the UPS. Because the voltage mutual inductor is connected to the low-voltage end of the transformer of a high-voltage electric transmission and distribution circuit, and the UPS is connected to the output end of the voltage mutual inductor, in the case of normal power supply for the circuit, the electrical switch-on circuit is directly supplied with power by the voltage mutual inductor; and in the case of short-circuit occurring in circuits at the both ends of the voltage mutual inductor, the electrical switch-on circuit is supplied with power by the UPS.

Description

The electric combined floodgate circuit U of high pressure relay switch PS electric supply installation
Technical field
The utility model belongs to the power transmission and transforming equipment technical field, relates to a kind of high pressure relay switch UPS electric supply installation.
Background technology
In the prior art; the electric combined floodgate circuit of high pressure relay switch mainly is made up of voltage transformer, comprehensive protector, electric switch knob and closing coil; voltage transformer is connected on high voltage source one end; high-tension electricity is converted into the power supply of 220V; power supply gas combined floodgate circuit uses; comprehensive protector, electric switch knob and closing coil are connected on the voltage transformer; when connecting electric switch knob; closing coil gets; the control end of closing coil drives the disconnect work of circuit breaker, realizes closing operation.
Because voltage transformer is connected on high voltage source one end; when the rear and front end of voltage transformer is short-circuited; electric combined floodgate circuit will quit work because of dead electricity; this moment circuit breaker afunction; high voltage source is to the relaying protection forfeiture of user's power supply circuits, and high voltage source major safety risks occur to the circuit of user's power supply.
Summary of the invention
For solving in the prior art; voltage transformer is connected on high voltage source one end; when the rear and front end of voltage transformer is short-circuited; electric combined floodgate circuit will quit work because of dead electricity; the problem that causes the afunction of circuit breaker; the utility model provides the electric combined floodgate circuit U of a kind of high pressure relay switch PS electric supply installation; the power supply of electric combined floodgate circuit is provided by voltage transformer; be connected with comprehensive protector on the voltage transformer; electric switch knob and closing coil; the disconnect of the control termination circuit breaker of closing coil; the input of voltage transformer is connected on the low-voltage coil end that high voltage source and user send the transformer between the electric wire; the output of voltage transformer connects UPS uninterrupted power supply, comprehensive protector; electric switch knob and closing coil are connected on the UPS uninterrupted power supply.
Adopt technique scheme; voltage transformer is connected on the step-down side of high voltage power transmission and transforming circuit; its control difficulty reduces relatively; UPS uninterrupted power supply of output termination at voltage transformer; when voltage transformer two-termial line normal power supply; directly electric combined floodgate circuit is powered by voltage transformer; at this moment; ups power obtains charging; when short circuit appears in the voltage transformer two-termial line; power to electric combined floodgate circuit by the UPS uninterrupted power supply, the situation of electric like this combined floodgate circuit with regard to not occurring can not get powering, the circuit protection function of circuit breaker obtains more reliable guarantee.
