Abstract
The invention relates to a gas-insulated metal-enclosed switchgear based on a stand-alone switch element in the power industry, which comprises a cable terminal, a line disconnecting switch, a voltage transformator, a current transformator, a circuit breaker, a bus isolating switch, an earthing isolator, and a circuit breaker operating mechanism, wherein one end of the line disconnecting switch is connected with the cable terminal, and the line disconnecting switch is respectively connected with the voltage transformator and the current transformator; and an interface of the circuit breaker is connected with the current transformator, and the circuit breaker is respectively provided with the bus isolating switch and the earthing isolator. The circuit breaker operating mechanism is arranged below the circuit breaker, thereby relieving operating force; buses of the bus isolating switch and the earthing isolator are arranged in a chamber of the circuit breaker, thereby reducing the space of the whole machine; and end interfaces of the circuit breaker are designed into standard interfaces, and three groups of arc extinguishing chambers are arranged in a structure with a shape like a Chinese character 'pin', thereby having strong universality and even distribution of electric fields.
Description
Technical field
The present invention relates to a kind of electric equipment of power industry, specifically a kind of based on single upright switch element basis, a kind of Cubicle Gas-Insulated Switchgear that isolating switch, circuit breaker, instrument transformer are combined.
Background technology
Relevant by retrieval patent documentation does not retrieve a kind of Cubicle Gas-Insulated Switchgear identical with structure of the present invention at present as yet.Existing power industry generally adopts the mode of Dan Li to install to measurement, protection and control appliance for electricity consumption to be connected, need take very big place because each single upright equipment is installed, and the installation of equipment to be time-consuming, so the time of putting into operation of engineering is longer relatively.
Summary of the invention
The objective of the invention is to provide a kind of, a kind of Cubicle Gas-Insulated Switchgear with compact conformation, dependable performance based on single upright switch element basis.
The invention is characterized in: a kind of Cubicle Gas-Insulated Switchgear that on the basis of considering dependable performance, compact conformation, highly versatile, is designed to comprise cable termination, line disconnecting switch, voltage transformer, current transformer, circuit breaker, bus isolating switch, isolation earthing switch, circuit breaker operation mechanism, end at line disconnecting switch is connected with cable termination, on the interface of line disconnecting switch, be connected with voltage transformer, current transformer respectively, be provided with circuit breaker operation mechanism in the bottom of circuit breaker; One interface of described circuit breaker is connected with current transformer, is respectively equipped with bus isolating switch, isolation earthing switch on the scene 2 line interface of circuit breaker.
The end interface of described line disconnecting switch is the standard type interface.
Cable termination that described line disconnecting switch is connected with outside line or outlet sleeve pipe can be arranged on the interface of upper and lower end.
Each end interface of described circuit breaker is the standard type interface.
The end interface that described circuit breaker is connected with bus isolating switch, isolation earthing switch is interchangeable version.
Three groups of arc control device of described circuit breaker are arranged in the same housing, and three groups of arc control device cross sections are arranged into " product " font version.
During use, insert outside line from cable termination, via line isolating switch branch, close control, and through voltage transformer, current transformer measurement control, external impressed current is inserted circuit breaker, through circuit breaker control electric current is divided into two loop buses again, links to each other with the main bus bar in power station with isolation earthing switch by bus isolating switch respectively.The disconnection of circuit, connection are operated by circuit breaker operation mechanism and are carried out.
Advantage of the present invention is: because circuit breaker operation mechanism is arranged on the below of circuit breaker, conducting rod is disconnected move down when mobile, thereby alleviated operating physical force, machine gravity is moved down, make complete machine more stable, and reduced the vibration of operation; Because it is indoor that the bus of bus isolating switch, isolation earthing switch is arranged on the circuit breaker device, thereby reduced the complete machine space; Because the end interface of circuit breaker all adopts the standard type Interface design, thus highly versatile, adapted new-style electronic instrument transformer or conventional electromagnetic transformer easily; Because three groups of arc control device of circuit breaker are arranged in the same housing, are arranged into " product " font version, thereby make Electric Field Distribution even, under the comparatively big situation of safe distance, the volume of circuit breaker are reduced; Because the upper and lower interface of line disconnecting switch adopts the standard type interface, thereby can realize that upper and lower end inserts outside line according to concrete needs; Because compact conformation, highly versatile, dependable performance are so there is very big practical and popularizing value.
