Abstract
The invention relates to a manual auto voltage reducing starter, which is composed of a casing, an auto-transformer, a contact system, an operating mechanism and the like. The manual auto voltage reducing starter is simple, practical, low in cost and capable of being applied to infrequent reduction voltage starting and shutting-down of alternating current 380v and 14-75kw squirrel-cage motor. The manual auto voltage reducing starter overcomes the shortcomings of existing products, is provided with a temperature control device, can avoid and reduce various accidents caused by overload, overcurrent, overheating, improper operation and improper maintenance because of various reasons.
Description
One, technical field
The present invention relates to a kind of starter, relate in particular to a kind of manual auto voltage reducing starter.
Two, background technology
Starter is a kind of electric equipment of using always, and its safety is particularly important, and starter in use has overload, overcurrent, overheated operation, safeguards defectives such as improper at present, is prone to cause various accidents.
Three, summary of the invention
For the deficiency and the defective that overcome prior art, the present invention provides a kind of manual auto voltage reducing starter, the present invention can prevent effectively because a variety of causes transship, overcurrent, overheated and the generation accident.
The objective of the invention is to realize like this:
Manual auto voltage reducing starter of the present invention is made up of shell, autotransformer, contact system, operating mechanism etc., it is characterized in that on output, the input terminal attemperating unit being housed, and warning device is housed on the shell.It is characterized in that attemperating unit can be thermostat, temperature switch, thermal protector, thermistor.The temperature-control range that it is characterized in that attemperating unit can be set early warning temperature and break-off signal according to protection range.It is characterized in that attemperating unit can be one two or N.
Advantage of the present invention is following:
Manual auto voltage reducing starter of the present invention, simple, practical, cost is low, it goes for exchanging the frequent reduced-voltage starting of 380v14-75kw MC and stops.It has overcome the deficiency of existing product, has increased attemperating unit, it can avoid and reduce because of the overload that a variety of causes causes, overcurrent, overheated, operate and safeguard the improper various accidents that cause.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified
Fig. 1 is a manual auto voltage reducing starter embodiment sketch map of the present invention
1. manual auto voltage reducing starters among the figure, 2. output, input terminal, 3. attemperating unit, 4. warning device 5. shells.
Five, embodiment
