An insulating separating plate is arranged between a high-voltage part contact and a low-voltage moving contact on the insulating main shaft. The isolation on-load capacity-regulating switch has the advantages of being simple in structure, reasonable in arrangement, convenient to install, safe and reliable to use, and the like.
Description
Technical field
The utility model belongs to the transformer switch field, relates in particular to a kind of isolated loaded capacity-regulated switch.
Background technology
Electric energy will repeatedly boost by power transformer from the power plant to user, step-down.Although the efficient of transformer own is very high, many because of number of units, capacity is large, its total losses are still very large.According to statistics, the total losses of China's transformer account for 10% of system's energy output; And in the intermediate and low electric network loss that accounts for electrical network total losses 60% ~ 65%, 70% loss is approximately arranged on distribution transformer.If transformer loss can reduce by 1%, the annual over ten billion degree electricity of just can saving.Because the seasonality of rural power grids load is strong, the load peak-valley difference is large, causes the loss ratio of present China rural power grids distribution transformer larger, causes the waste of a large amount of electric power resources.
Loaded capacity-regulated transformer is a kind of transformer with two kinds of rated capacities of size, according to payload, utilize special capacitance switch to come (dividing without excitation capacity transfer and loaded capacity-regulated) connected mode of conversion winding, realize the switching (transformer high-pressure side winding when large capacity is that D connects operation, is that Y connects operation during low capacity) between two kinds of different capabilities of transformer.The no-load loss of capacitance-adjustable transformer and load loss are all lower, and especially the total losses during light running are more much lower than the total losses of same capability other types transformer.Low without little, the online controlled ability of excitation capacity transfer transformer capacity, can not charged pondage, generally only carry out seaonal load and regulate, and can have influence on user's power supply reliability when regulating.Loaded capacity-regulated transformer can effectively solve and eliminate existing the problems referred to above and limitation without the excitation capacitance-adjustable transformer, energy auto-real-time monitoring and control, carry out capacity regulating according to actual load size reasonable ground, thereby further enlarge the scope of application of capacitance-adjustable transformer.
Loaded capacity-regulated switch of the prior art comprises housing, motor, quick mechanism, insulating cylinder, insulation spindle and contact system, and described contact system comprises low-pressure section and high-pressure section; Described contact system comprises the moving contact that is installed on the main shaft and the contact of deciding that is installed on the insulating cylinder.For fear of the electric field influence of contact system mesohigh part to low-pressure section, require high-pressure section and the larger insulation distance of low-pressure section, this just causes the height of insulation spindle and insulating cylinder to increase, and because of the parts on the moving contact more, in case the part of high-pressure section, wire dropping are overlapped on the low-pressure section, will cause device damage even cause major accident.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of isolated loaded capacity-regulated switch, and is simple in structure, easy for installation, safe and reliable.
To achieve the above object, the utility model has adopted following technical scheme:
Isolated loaded capacity-regulated switch comprises housing, motor, quick mechanism, insulating cylinder, insulation spindle and contact system, and described contact system comprises low-pressure section and high-pressure section; Described contact system comprises the moving contact that is installed on the insulation spindle and the contact of deciding that is installed on the insulating cylinder; Between high-voltage section contact and low pressure moving contact, be provided with insulating barrier on the described insulation spindle.
As preferably, described insulating barrier is set on the insulation spindle and rotation synchronous with it.
The utility model is owing to having adopted above technical scheme, between high pressure moving contact and low pressure moving contact, insulating barrier is set, can improve contact system mesohigh part to the impact of low-pressure section, improve both insulation levels, reduce two-part physical insulation required distance, intercept the casts such as part, wire, avoid cause damage of equipment and security incident, insulating barrier is installed on the insulation spindle simple installation together in company with movable contact system simultaneously.The utlity model has simple in structure, rationally distributed, simple installation, the advantage such as safe and reliable.
