Abstract
The utility model discloses and provides a device for connecting shore power and ship power. The device includes a shore power interface, a shore power cable, a shore power plug, a ship power socket, an electro-protection-control switch in ship, an electro-load interface in ship and a switch; and a single-phase three wire system is adopted by the above elements which are respectively accessed to a phase line (L), a null line (N) and an earth line (E). The device further includes an isolation transformer including a primary winding, a secondary winding and a shielding layer, and the secondary winding has a tap; the phase line (L) and the null line (N) in the ship power socket are connected with the primary winding of the isolation transformer after being in series with the electro-protection-control switch in ship, and the earth line (E) in the ship power socket is connected with an isolation winding or the shielding layer of the isolation transformer; and electro-loads in ship are all connected with the secondary of the isolation transformer, the earth line (E) in ship is connected with the tap in the secondary winding of the isolation transformer, and direct wire connection is prevented when shore power transmits electric power to electro-loads in ship.
Description
The utility model relates to the jockey of a kind of bank electricity and ship electricity.
Background technology
The electric network source that on ship, electricity consumption often connects on the bank by electric wire or cable, connector, switch etc. causes on ship; for electric installation; safety is obviously to need the factor of consideration; when short circuit or electric leakage; fuse melting or the tripping operation of GFCI protection switch; the ground wire of bank electricity is directly linked to the metal part of hull, can be caused electrolytic corrosion to occur.But, on ship, only connect live wire and center line and can cause unsafe situation to occur, because at this moment insure or GFCI protection switch cisco unity malfunction.Ways of addressing this issue often adopts installs bank electricity galvanic separation, but it can not solve the electrolytic corrosion that the ground wire of bank electricity is directly connected and inevitably produces with ground wire on ship, this electrolytic corrosion has reduced the useful life of boats and ships, has increased ship resistance, has affected the speed of a ship or plane.
In sum, in the jockey of bank electricity of the prior art and ship electricity, there is urgent problem.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of bank electricity of direct electrical connection and jockey of ship electricity that isolator transformer has been eliminated bank electricity and marine electric that have is provided.
The technical scheme that the utility model adopts is: it comprises bank electrical interface the utility model, shore connection cable, bank plug, ship electrical socket, on ship, on electricity protection control switch and ship, use electrical load interfaces, switch, above-mentioned each component is single-phase three wire system, access respectively phase line, zero line, ground wire, it also comprises isolating transformer, described isolating transformer comprises primary and secondary, between described primary and secondary winding, there are isolated windings or screen, in secondary winding, there is tap, phase line in described ship electrical socket and zero line are connected and after electricity protection control switch, are connected the armature winding of described isolating transformer on described ship, ground wire in described ship electrical socket connects isolated windings or the screen in described isolating transformer, on described ship, use electrical load interfaces, switch is all connected with described isolating transformer secondary and obtains power supply, tap on described ship in the secondary winding of ground wire and described isolating transformer is connected, bank electricity connects to having removed direct electric wire from during with electric loading transferring electric power on ship, described ground wire on the bank is not directly connected with ground wire on ship yet, all by magnetic, exchange and transmit.
The beneficial effects of the utility model are: due to the utility model, it comprises bank electrical interface, shore connection cable, bank plug, ship electrical socket, on ship, on electricity protection control switch and ship, use electrical load interfaces, switch, above-mentioned each component is single-phase three wire system, access respectively phase line, zero line, ground wire, it also comprises isolating transformer, described isolating transformer comprises primary and secondary, between described primary and secondary winding, there are isolated windings or screen, in secondary winding, there is tap, phase line in described ship electrical socket and zero line are connected and after electricity protection control switch, are connected the armature winding of described isolating transformer on described ship, ground wire in described ship electrical socket connects isolated windings or the screen in described isolating transformer, on described ship, use electrical load interfaces, switch is all connected with described isolating transformer secondary and obtains power supply, tap on described ship in the secondary winding of ground wire and described isolating transformer is connected, bank electricity connects to having removed direct electric wire from during with electric loading transferring electric power on ship, described ground wire on the bank is not directly connected with ground wire on ship yet, all by magnetic, exchange and transmit.So safety is played a key effect, eliminated electrolytic corrosion, extended the useful life of boats and ships, reduced ship resistance, improved the speed of a ship or plane.Can no longer need to install bank electricity galvanic separation simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory schematic diagram.
Embodiment
As shown in Figure 1, the present embodiment comprises bank electrical interface, shore connection cable, bank plug, ship electrical socket, on ship, on electricity protection control switch and ship, use electrical load interfaces, switch, above-mentioned each component is single-phase three wire system, access respectively phase line L, zero line N, ground wire E, it also comprises isolating transformer, described isolating transformer comprises primary and secondary, between described primary and secondary winding, there are isolated windings or screen, in secondary winding, there is tap, phase line in described ship electrical socket and zero line are connected and after electricity protection control switch, are connected the armature winding of described isolating transformer on described ship, ground wire in described ship electrical socket connects isolated windings or the screen in described isolating transformer, on described ship, use electrical load interfaces, switch is all connected with described isolating transformer secondary and obtains power supply, tap on described ship in the secondary winding of ground wire and described isolating transformer is connected, bank electricity connects to having removed direct electric wire from during with electric loading transferring electric power on ship, described ground wire on the bank is not directly connected with ground wire on ship yet, all by magnetic, exchange and transmit.
The concrete operation principle of bank electricity isolating transformer as shown in Figure 1; the bank electricity live wire of AC220V, zero line, ground wire are connected with ship electricity by shore connection cable, bank plug, socket; if there is no bank electricity isolating transformer; on ship, power consumption equipment is excessively short-circuited or leaks electricity once load; protective switch of the short circuit K1 tripping operation; the ground wire of bank electricity is to be directly connected with the ground wire on ship, has inevitably produced electrolytic corrosion.If but install bank electricity isolating transformer additional after protective switch of the short circuit K1; the ground wire of bank electricity is through the screen of isolating transformer; be that the Weak current that harmonic wave many in alternating current and stray magnetic field produce is that conductively-closed has been fallen after the isolated windings in the middle of the primary and secondary of transformer or screen; so just can not cause electrolytic corrosion to hull; extended the useful life of boats and ships; reduce ship resistance, improved the speed of a ship or plane.
