Description
Technical field
The present invention relates to power domain, in particular it relates to relay protection type wall bushing.
Background technology
Capacitive type wall bushing is mainly used in power plant, transformer station guiding high pressure or supertension wire through building
Wallboard, as conduction current-carrying and the insulation of high pressure wallboard over the ground and be mechanically fixed use.Capacitive type wall bushing is divided into vertical and sleeping
Formula two kinds, is all-sealed structure.Existing wall bushing, when carrying out operation through walls, can only be held in the hand always, if also wanting
Pull high-voltage line to pass wall-through hole simultaneously, if high-voltage line is wound around, need extra workman to carry out below coordinating and could being total to
The same operation through walls completing high-voltage line, reduces efficiency.It addition, existing wall pipe is all directly through high-voltage conducting wires, and high
Piezoelectricity is to cannot directly access measurement and protection device, but we need to survey the electric current of the high-tension line accessed sometimes
Amount, checks that installing high-tension line the most normally works, and the high-tension line of part the most through walls the most normally works, and present
Wall pipe does not reaches such requirement.
Summary of the invention
The technical problem to be solved is to provide relay protection type wall bushing, and this device i.e. has only to a people
The reason line operation of the individually operated operation through walls that can realize high-tension line and high-voltage line, and this device can be by high-tension line
It is practical that big electric current is converted into small area analysis, supply measuring instruments and protection device, measures the most normal work of high-tension line at place through walls
Make more convenient.
The present invention solves the problems referred to above the technical scheme is that relay protection type wall bushing, including sleeve body,
Indoor insulator, current transformer, outdoor insulator, installing plate through walls and adpting flange, between described indoor insulator and outdoor insulator
Being fixedly connected by adpting flange, indoors the front of motor of insulator and outdoor insulator and adpting flange is respectively provided with wiring
Plate, the front of motor of outdoor insulator and adpting flange also sets up conservator and brute spring, conservator and brute spring and is respectively positioned on wiring
Between plate and outdoor insulator;Described sleeve body level crosses the center of adpting flange, and the two ends of sleeve body respectively penetrate family
The cavity of interior insulator and the cavity of outdoor insulator, the end of sleeve body is also connected with patch panel;Described sleeve body includes center
Contact tube and be wrapped in the capacitor core outside the copper pipe of center, described indoor insulator also sets up on the connection end of adpting flange
Current transformer and installing plate through walls, on the outer wall of installing plate right angle setting insulator indoors through walls, installing plate through walls is positioned at electricity
Between current transformer and adpting flange, current transformer overlaps indoors on insulator.The access of current transformer, it is possible to by high-voltage line
High electric current in road is converted to low current in proportion, and the secondary side of current transformer just can directly connect measuring instruments, carry out relay
Protection etc., thus convenient high-tension line is detected, the whether safe operation of the high-tension line of part the most through walls, then with continue
Electrical equipment coordinates, and is short-circuited or during overload fault at circuit, provides signal cut faulty circuit, protection power supply to relay system
The safety of system.Wall bushing is when carrying out operation through walls, owing to installing plate through walls pushes down metope, even if not grasping through walls
Sleeve pipe, wall-through hole does not haves the situation of downward landing yet, when pulling high-voltage line to pass wall-through hole, if high-voltage line twines
Around, only wall-through hole need to be allowed to stay on the wall, then the high-voltage line being wound around is managed straight operation, it is not necessary to extra workman coordinates
Complete the operation through walls of high-voltage line, improve work efficiency.
Described installing plate through walls is symmetrical about indoor insulator, also sets up chute on installing plate through walls, arranges in chute
The tip support that can slide up and down.When uneven near wall, it has not been convenient to when installing plate through walls is fixed, can
Move up and down the tip support being positioned at installing plate chute through walls, find the position being beneficial to fix on metope, then by point
Portion's support member is inserted on body of wall, it is to avoid wall bushing landing, conveniently measures circuit, and whether detection circuit occurs different
Often.
Two of described indoor insulator is respectively provided with tip support.Fixing more firm.
Described indoor insulator is also vertically arranged fuel tank on the connection end of adpting flange, and fuel tank crosses indoor insulator, at family
The bottom of interior insulator also sets up bleeder plug.After the oil in sleeve pipe expands, can be flowed in fuel tank under the effect of the pressure, keep away
The oil exempting to expand produces huge pressure to casing wall, damages sleeve pipe by pressure.
Described outdoor insulator also sets up measurement lead terminal with the connection end of adpting flange, measures lead terminal and capacitance core
Son connects.Capacitor core is aluminium foil as pole plate, the series connection concentric circular body capacitance that forms as contrasted between solid dielectric using oil compression cable paper
Device.
Multi-turn it is uniformly distributed for holding the annular expenditure parts of transformer oil on described indoor insulator and outdoor insulator.Side
Just the uniform oil in reserve of inside pipe casing, increases storage oil and contacting between capacitor core.
Described conservator is provided with the hole for evacuation and immersion oil.The annular of distribution on indoor insulator and outdoor insulator is made to prop up
Go out in the oil in parts can penetrate sleeve body and participate in the oil circulation of whole sleeve pipe.
Being provided with patch panel end on described outdoor insulator and also set up grading ring, grading ring is positioned at the outside of patch panel.Ensure
Firmly connecting and safety of patch panel.
To sum up, the invention has the beneficial effects as follows:
1, the access of current transformer, it is possible to the high electric current in high-tension line is converted in proportion low current, convenient to high pressure
Circuit detects, and particularly detects the high-tension line whether safe operation of part through walls, then coordinates with relay, sends out at circuit
When raw short circuit or overload fault, provide signal cut faulty circuit, the safety of protection electric power system to relay system.
2, wall bushing is when carrying out operation through walls, owing to installing plate through walls pushes down metope, even if not grasping through walls
Sleeve pipe, wall-through hole does not haves the situation of downward landing yet, when pulling high-voltage line to pass wall-through hole, if high-voltage line twines
Around, only wall-through hole need to be allowed to stay on the wall, then the high-voltage line being wound around is managed straight operation, it is not necessary to extra workman coordinates
Complete the operation through walls of high-voltage line, improve work efficiency.
3, when uneven near wall, it has not been convenient to when installing plate through walls is fixed, can move up and down to be positioned at and wear
Tip support in wall installing plate chute, finds the position being beneficial to fix on metope, is then inserted into by tip support
On body of wall, it is to avoid wall bushing landing, conveniently measuring circuit, whether detection circuit there is exception.
