Abstract
The utility model relates to a totally enclosed weight-driven starting relay for refrigeration compressor using a R600a working medium, comprising a weight hammer, a dynamic and static contact, a filling-in bits which is respectively connected with the static contact and an external system and an irregular socket. A sealing insulating casing is arranged outside the weight-driven starting relay components. Inactive gas or other flame-proof gas is charged into the cavity of the casing. The utility model can avoid the safety problem caused by external leakage flow of the electric sparks when the weight-driven starting relay is in use. The utility model has the advantage of small loss, and the power-efficiency ratio of the R600a compressor is enhanced.
Description
(1) technical field: the utility model belongs to the starting drive of piston compressor, is specifically related to a kind of R600a Fully Closed Heavy Hammer Starter for Refrigerant Compressor.
(2) background technique: at present, the small-power piston compressor generally starts with heavy hammer started device and positive temperature coefficient thermistor (PTC) starter, but the heavy hammer started device of Yin Putong has electrical spark to produce when working, can not be used in the compressor of explosive working medium such as R600a, PTC starter contactless switch, overcome the above-mentioned shortcoming of heavy hammer type starter, so R600a working medium compressor generally starts with the PTC starter.But PTC participates in the operation of motor for a long time, himself generates heat to consume certain power, electric efficiency is descended to some extent, thereby influence the Energy Efficiency Ratio of compressor, and this is a fatal defective to high-efficient compressor.
(3) summary of the invention: the purpose of this utility model just provides and a kind ofly can prevent again that when not increasing the starter working loss electrical spark from leaking, safe and reliable R600a Fully Closed Heavy Hammer Starter for Refrigerant Compressor.
The utility model comprises weight, sound contact and inserted sheet that is connected with stationary contact and external system respectively and special-shaped socket, outside described heavy hammer started device assembly, a sealed insulation shell is set, and charges into inert gas or other fire-retardant gas in this cavity pocket of outer cover.
This heavy hammer started device is that electromagnetic coil is connected on (not shown) in the compressor electric motor main winding, and before the startup, weight makes dynamic and static contact separately because of the self gravitation effect; During startup, because the electric motor starting electric current is bigger, the bigger electromagnetic force of electromagnetic coil generation makes weight overcome self gravitation and spring force moves upward, and makes dynamic and static make contact, and secondary winding is connected (not shown), keep less electric current operation behind the electric motor starting, the electromagnetic force that electromagnetic coil produces is less than weight gravity, and weight falls, and the contact separately, secondary winding disconnects, and starting is finished.After finishing startup, the contact separates fully, and no longer consumed power is very favourable to compressor.And the heavy hammer started device electrical spark that the contact is produced when starting is sealed in the insulation crust, can the outside not exerted an influence, thereby has guaranteed the Security of compressor; Compare with the PTC starter, consume for a short time, improved the Energy Efficiency Ratio of R600a compressor.
(4) description of drawings:
Fig. 1 is the utility model normal cross section structural representation.
(5) embodiment:
Referring to accompanying drawing, the utility model comprises weight 1, movable contact 2, stationary contact 3, this stationary contact is connected with inserted sheet 4, special-shaped socket 5 respectively, and a sealed insulation plastic casing 6 is set outside said modules, and the utility model is connected with external system by inserted sheet 4, special-shaped socket 5; In described cavity, charge into inert gas or fire-retardant gas.
