Abstract

The utility model discloses an electric furnace transformer's loop construction, including coil (1) and reactor (2), take a fancy to reactor (2) that all are equipped with a correspondence in each of coil (1), arbitrary arbitrary shunting terminal of taking a fancy to of coil (1) is connected through the both ends of two route ways with reactor (2) that should take a fancy to respectively, , then puts through arbitrary shunting terminal of taking a fancy to of coil (1) when being connected with reactor (2) the near -end circuit that should take a fancy to through switch contact this reactor (2), otherwise, then breaks off arbitrary shunting terminal of taking a fancy to of coil (1) when being connected with reactor (2) the distal end circuit that should take a fancy to through switch contact this reactor (2), above -mentioned loop construction makes arbitrary shunting terminal of taking a fancy to of this coil (1) to establish ties with reactor (2) that should take a fancy to. The utility model discloses an every grade of voltage of electric furnace transformer output can both series reactor with withdraw from the reactor, suitable using widely.

Description

A kind of loop construction of furnace transformer
Technical field
The utility model relates to furnace transformer technical field, specifically a kind of arbitrary arbitrary tap terminals in mutually that can allow coil loop construction of the furnace transformer that carries out pressure regulation of can both connecting with this reactor in mutually.
Background technology
Conventional furnace transformer is current-limiting reactor under maximum output voltage, and therefore the voltage regulating mode of this kind of furnace transformer is single.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, the loop construction that provides a kind of arbitrary arbitrary tap terminals in mutually that can allow coil can both connect with this reactor in mutually the furnace transformer that carries out pressure regulation.
The purpose of this utility model solves by the following technical programs:
A kind of loop construction of furnace transformer, comprise coil and reactor, all be provided with a corresponding reactor in each of coil in mutually, it is characterized in that: arbitrary arbitrary tap terminals in mutually of described coil is connected with the two ends of this reactor in mutually by two-way circuit respectively, in the time that being connected with this reactor near-end circuit in mutually by switch contact, arbitrary arbitrary tap terminals in mutually of coil connects this reactor, otherwise in the time that being connected with this reactor distal line in mutually by switch contact, arbitrary arbitrary tap terminals in mutually of coil disconnects this reactor, arbitrary arbitrary tap terminals in mutually that above-mentioned loop construction makes this coil can both be connected with this reactor in mutually.
The three-phase voltage of described coil adopts Angle connection.
The three-phase voltage of described coil adopts Y-connection.
The utility model has the following advantages compared to existing technology:
The utility model is by being connected with the two ends of this reactor in mutually by two-way circuit respectively in arbitrary arbitrary tap terminals in mutually of coil, the arbitrary arbitrary tap terminals in mutually that makes this coil can both be connected with this reactor in mutually, make this furnace transformer voltage regulating mode for every grade of voltage of output can both current-limiting reactor and exit reactor, adopt cross-over connection pressure adjusting structure that reactor is connected and excision, excessively arrive another gear by neutral mode, so repeatedly, realize each gear voltage-regulation, suitable promoting the use of.
Brief description of the drawings
The loop construction three-phase voltage Angle connection schematic diagram that accompanying drawing 1 is furnace transformer of the present utility model.
Wherein: 1-coil; 2-reactor.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of loop construction of furnace transformer, comprise coil 1 and reactor 2, all be provided with a corresponding reactor 2 in each of coil 1 in mutually, arbitrary arbitrary tap terminals in mutually of this coil 1 is connected with the two ends of this reactor 2 in mutually by two-way circuit respectively, in the time that being connected with these reactor 2 near-end circuits in mutually by switch contact, arbitrary arbitrary tap terminals in mutually of coil 1 connects this reactor 2, otherwise in the time that being connected with these reactor 2 distal lines in mutually by switch contact, arbitrary arbitrary tap terminals in mutually of coil 1 disconnects this reactor 2, arbitrary arbitrary tap terminals in mutually that above-mentioned loop construction makes this coil 1 can both be connected with this reactor 2 in mutually. the three-phase voltage of this coil 1 not only can adopt Angle connection but also can adopt Y-connection, and the structure shown in Fig. 1 is the situation of the three-phase voltage employing Angle connection of this coil 1.
The utility model is by being connected with the two ends of this reactor 2 in mutually by two-way circuit respectively in arbitrary arbitrary tap terminals in mutually of coil 1, the arbitrary arbitrary tap terminals in mutually that makes this coil 1 can both be connected with this reactor 2 in mutually, make this furnace transformer voltage regulating mode for every grade of voltage of output can both current-limiting reactor and exit reactor, adopt cross-over connection pressure adjusting structure that reactor is connected and excision, excessively arrive another gear by neutral mode, so repeatedly, realize each gear voltage-regulation, suitable promoting the use of.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
