Abstract
The utility model discloses a 10kV system emergent electric supply installation which relates to a 10kV emergent electric supply installation of transformer substation, in particular to a 10kV system power-off electric supply and protection installation of transformer substation. The 10kV system emergent electric supply installation includes a cabinet, a cable incoming sleeve and a cable outgoing sleeve. Clapboard is arranged in the cabinet to divide the cabinet into four working cabinets, which respectively include an incoming cabinet, an outgoing cabinet, the working cabinet of a used transformation voltage mutual inductor and a relay protection working cabinet. When in use, the incoming sleeve is connected with the 10kV side of a transformer through a cable. Electricity of each 10kV outgoing line is supplied through the incoming cabinet, a busbar inside the cabinet, the outgoing cabinet and the outgoing sleeve. The used transformer can supply a 380kV power source for temporary electricity. A relay protection device has the functions of master transformer protection and line protection. A 0.2S-grade electric energy meter is equipped in the cabinet so as to meet the requirement of electricity measuring. A plurality of flying rings are arranged in the ceiling of the electric supply cabinet to provide convenience for moving. The 10kV system emergent electric supply installation is suitable for 10kV system transformation and emergency repairing so as to improve the electric supply reliability.
Description
Technical field
The utility model relates to a kind of 10kV of transformer station Emergency power supply unit, is applicable to the replacing of 10kV high-voltage board switch cubicle, improvement project and the repairing work of 10kV system, is a kind of guarantor's electric supply installation of the 10kV of transformer station system blackout.
Background technology
The original old-fashioned switch cubicle of more existing transformer stations service life for a long time, can't seal fully, five anti-devices be not installed in the cabinet, safety measures such as components and parts can't be accomplished to prevent dust, protection against the tide, department's bus is exposed outside, has potential safety hazards such as short circuit accident.These switch cubicles need be replaced with the armored metal closed switch cabinet altogether, need the 10kV bus to have a power failure in the transformation process, cause each bar 10kV outlet to have a power failure, the general transformation duration is longer, influence power supply reliability, in addition, when the 10kV distribution system has an accident, cause the stoppage in transit of outlet switch cubicle fault or bus, cause and to power for the user.
Summary of the invention
In order to solve the emergency service under the 10kV system blackout situation; the utility model provides a kind of emergency service cabinet; this powering shelf can normally move at main transformer; under the 10kV system blackout situation; emergency power supply is provided, and 380V can be provided used AC power, guarantee the normal operation of low-voltage alternating-current power supply in the institute; have main transformer protection and route protection function, convenient moving transported use.
The technical scheme that its technical problem that solves the utility model adopts is: this powering shelf is made of incoming line cabinet, outlet cabinet, used change, voltage transformer cabinet, relaying protection cabinet.When needing emergency service, with cable main transformer 10kV side joint is gone into the incoming line cabinet bushing, bus is connected to the outlet cabinet in first, second isolating switch by incoming line cabinet and circuit breaker, the cabinet, receive the outlet sleeve pipe by outlet cabinet first, second isolating switch and circuit breaker, connect the outlet sleeve pipe with cable and be incorporated into the 10kV outlet, be each bar 10kV outlet power supply.Used change cabinet guarantees electricity consumption in the institute with 10kV voltage step-down 380V.Voltage transformer, current transformer are measured 10kV voltage, electric current, have main transformer protection, route protection function, under the situation that the 10kV bus has a power failure, reach the purpose of reliable power supply.
The beneficial effects of the utility model are: can normally move at the transforming plant main transformer depressor, under the situation of 10kV system blackout, provide emergency power supply, provide safeguard for production, household electricity are provided, guarantee this substation's electricity consumption normal power supply simultaneously, improved power supply reliability.
Description of drawings
Fig. 1 is an elevation of the present utility model.
Fig. 2 is a ground plan of the present utility model.
Fig. 3 is a key wiring diagram of the present utility model.
Among the figure, 1. entrance bushing; 2. outlet sleeve pipe; 3. high pressure incoming line cabinet; 4. high-voltage terminal cabinet; 5. protection screen; 6. inspection socket; 7. institute's time variant voltage instrument transformer cabinet; 8.PT used cabinet.
Embodiment
In Fig. 1, the emergency service cabinet adopts the metal-enclosed type high-tension switch cabinet, can prevent that toy from entering.Long is 2900mm, wide 2450mm, high 2870mm.High-tension switch cabinet should possess the mistake of preventing and divide, closes by mistake circuit breaker; Prevent the on-load branch, close isolating switch; Prevent to send when earthed switch from closing a floodgate; Prevent splice grafting ground switch when charged; Prevent the mistakenly entering charged chamber five-term measure.
Among Fig. 2; the emergency service cabinet is separated into incoming line cabinet, outlet cabinet, all time variant voltage instrument transformer cabinets, four parts of relaying protection cabinet; adopt the high-quality cold-rolled steel sheet to isolate between the each several part, its thickness is enough to guarantee integral intensity, prevents to bring disaster to the adjacent switch cabinet because of this cabinet fault.Among Fig. 3, incoming line cabinet is by 2 GN22-10 type isolating switches, 1 group of ZN28G-12 type vacuum circuit-breaker, and the LZZBJ-10/0.5/30 current transformer constitutes.The outlet cabinet is connected to the outlet cable by 2 groups of GN22-10 isolating switches, the disconnected device of 1 group of ZN28G-12, and used change cabinet is made of 1 SC9-50 10/0.410kV transformer and 1 JDZJ-12 type voltage transformer and lightning arrester.The relaying protection cabinet provides main transformer protection and circuit fast tripping protection.
When electric substation's 10kV outlet is broken down or 10kV bus need stop transport the time, lead to high-voltage board 10kV bus and main transformer 10kV side disconnects with original, with the 10kV cable main transformer 10kV side sleeve pipe is linked to each other with the Emergency power supply unit entrance bushing.With the 10kV cable 10kV outlet is linked to each other with the 10kV outlet sleeve pipe of emergency service cabinet, introduce electric substation's ac panel, guarantee institute's electricity consumption normal power supply with will the meet an urgent need used change of cabinet of 380V power cable.
Outlet cabinet first, the second of closing isolating switch, incoming line cabinet first, the second of closing isolating switch, the outlet cabinet breaker that closes, the circuit breaker of the incoming line cabinet that closes, assurance 10kV system safety is reliably powered.
