Abstract
The utility model relates to a four-in-one combined electrical appliance, which is an inseparable combined electrical product and assembles mutual independent a capacitance graded bushing, a current mutual inductor, a voltage mutual inductor and an isolation switch together. A main insulation of the capacitance graded bushing is also a main insulation of the current mutual inductor and the voltage mutual inductor, and the capacitance graded bushing is also a post of the isolation switch. Therefore, the utility model has small size, low cost and few accident points and is suitable for urban compact type indoor substations.
Description
The utility model relates to high-voltage electrical equipment, especially is suitable for indoor electric substation.
In at present traditional indoor electric substation high-voltage electrical equipments such as circuit breaker, current transformer, voltage transformer, isolating switch, condenser-type terminal are arranged, wherein circuit breaker is made of insulation column and arc control device, current transformer is made of winding and secondary winding, voltage transformer is made of capacitor voltage divider and medium voltage transformation device, and isolating switch is made of a rotating insulation column in centre and two fixed insulation pillars and conducting rod.Shortcomings such as these equipment are separate, and every kind of equipment occupies the space, make preparations for sowing and leave operating clearance between the equipment, therefore exist construction area big, and the autonomous device investment is big, accident point is many.
The purpose of this utility model is that condenser-type terminal, current transformer, voltage transformer, isolating switch are combined into a combined electrical apparatus product, is characterized in reducing significantly construction area, reduces high-tension apparatus investment and accident point.
The purpose of this utility model is achieved in that on the condenser-type terminal that usefulness through walls or transformer are used and is with several secondary winding, and then the condenser-type terminal guide rod is that a winding and the secondary winding that is enclosed within on the condenser-type terminal are formed current transformer; The condenser-type terminal main capacitance links to each other with the medium voltage transformation device of capacitance type potential transformer by end screen outlet terminal, forms capacitance type potential transformer; Form isolating switch at the moving contact that placement isolating switch on the condenser-type terminal binding post is decided on contact and the rotating insulation column, the main insulation of its condenser-type terminal also is the main insulation of current transformer, capacitance type potential transformer, be that main body is combined into current transformer, capacitance type potential transformer and isolating switch like this with the condenser-type terminal, become the four unification combined electrical apparatuses of forming by condenser-type terminal, current transformer, voltage transformer and isolating switch.
Owing to take technique scheme, this combined electrical apparatus has been saved current transformer, the main insulation accident of current transformer and voltage transformer has been reduced in voltage transformer and half occupied space of isolating switch, is applicable to the city indoor electric substation of tight type of 60-220kv.
Below in conjunction with example figure the utility model is further specified:
First kind of embodiment of Fig. 1 is that transformer is formed four unification electrical equipment with condenser-type terminal and current transformer, voltage transformer and isolating switch.
Second kind of embodiment of Fig. 2 is through walls with condenser-type terminal and current transformer, voltage transformer and isolating switch composition four unification combined electrical apparatuses.
Among the figure 1, condenser-type terminal 2, secondary winding 3, condenser-type terminal end screen leading-out terminal 4, capacitance type potential transformer medium voltage transformation device 5, be installed in the isolating switch that isolating switch on the condenser-type terminal decides to have in contact 6, the isolating switch on the conducting rod 7 of two moving contacts, rotating insulation column 8, the sulfur hexafluoride breaker and decide contact 9, transformer 10, wall 11, sulfur hexafluoride breaker
Condenser-type terminal among Fig. 1 (1) inserts secondary winding (2), has formed current transformer, is installed on the transformer; Condenser-type terminal end screen leading-out terminal links to each other with capacitance type potential transformer medium voltage transformation device (4), forms capacitance type potential transformer; The rotating conducting rod (6) that isolating switch is decided contact (5) and had two moving contacts is installed at condenser-type terminal terminals place, and sulfur hexafluoride breaker (11) is upward decided contact (8) composition isolating switch, conducting rod is installed on the rotating insulation column (7), rotates the purpose that insulation column reaches deciliter isolating switch.
Condenser-type terminal among Fig. 2 (1) inserts secondary winding (2), has formed current transformer, is installed on the wall; Condenser-type terminal end screen leading-out terminal links to each other with capacitance type potential transformer medium voltage transformation device (4), forms capacitance type potential transformer; The rotating conducting rod (6) that isolating switch is decided contact (5) and had two moving contacts is installed at condenser-type terminal terminals place, and sulfur hexafluoride breaker (11) is upward decided contact (8) composition isolating switch, conducting rod is installed on the rotating insulation column (7), rotates the purpose that insulation column reaches deciliter isolating switch.
