Abstract
The utility model relates to a protector for a compressor. The utility model is characterized in that the protector is composed of a delay circuit, a relay and conducting wires, wherein, one end of the delay circuit is connected in series with a heat protector for a compressor by a conducting wire, the other end of the delay circuit is connected in series with the relay by another conducting wire, and a contact of the relay for controlling the delayed start of the compressor is connected in series with the other end of the heat protector for a compressor. The utility model has the advantage that the product can effectively prevent the compressor from being burnt out; the utility model also has the advantages of simple structure, low production cost and convenient development. The utility model can be widely used for compressors of refrigerators, deep freezers and air-conditioners.
Description
The utility model relates to a kind of refrigerant compressor safety guard, particularly a kind of compressor protector.
At present, China is on the low side in summer and peak of power consumption period network voltage, and refrigerant compressor in use cuts off the power supply, the then fragile compressor that restores electricity in the short time, and it is former because after the compressor outage, the 3-5 minute ability of should delaying time is started once more.In the general refrigerant compression machine equipment thermal protector is installed all; the characteristic that existing thermal protector has that overload 5-20 cut off the power supply second, 5-20 resets and switches on second; to cause the thermal protector long term overloading as voltage is on the low side; to making compressor burn damage, so just formed the contradiction that thermal protector can not effectively not protected compressor.
The purpose of this utility model is to design a kind of compressor protector, and it can prevent the generation of above-mentioned situation effectively, plays the effect that the protection compressor is not damaged.
The technical solution of the utility model: a kind of compressor protector; it is characterized in that it is by delay circuit; relay and lead are formed; said delay circuit one end is connected in series compressor thermal protector according to lead; its other end is connected in series relay according to lead, and the contact of the relay of control compressor start time-delay is serially connected on the thermal protector other end of compressor according to lead.
Superiority of the present utility model is: 1, adopt this product can effectively prevent burning of compressor; 2, simple in structure, production cost is low, is convenient to exploitation, can be widely used in refrigerator, refrigerator-freezer and compressor of air conditioner.
Further specify present technique below in conjunction with drawings and Examples.
Fig. 1 is the overall structure schematic diagram of the related a kind of compressor protector of the utility model.
Fig. 2 is the user mode structural representation of the related a kind of compressor protector of the utility model.
Wherein E is a thermal protector, and D is a compressor, and Q is a starter relay, and BH is a compressor protector, and J is the relay in the compressor protector, and J1 is the contact of J, and a, b, c are lead, and YS is a delay circuit.
Embodiment: a kind of compressor protector (see figure 1); it is characterized in that it is by delay circuit YS; relay J and lead a, b, c form; said delay circuit YS one end is according to lead a serial connection compressor thermal protector E; its other end is according to lead c serial connection relay J, and the contact J1 of the relay J of control compressor start time-delay is serially connected on the thermal protector E other end of compressor according to lead b.
Above-mentioned said delay circuit YS can take conventional transistor delay circuit.
Operation principle of the present utility model is: when the compressor fail to start, overheat protector E cuts off the power supply (seeing accompanying drawing 2), and at this moment electric current is finished the loop through a, c and compressor D starter relay Q.Compressor protector BH starts working, the relay J adhesive, and contact J1 disconnects, and cuts off the path of lead b and c.Even this moment, overheat protector recovered ortho states, compressor D can not work, and it must could start after 5 minutes once more in motor protector time-delay to be compressed, has so just solved the contradiction of overheat protector E and compressor D, thereby has played the effect of protection compressor.This compressor protector also has the function that the protection compressor is not burnt under the state of low-voltage and long-time energising, its reason be the every work of overheat protector once, compressor protector was just delayed time 5 minutes, had improved the compressor switching ratio of electricity time.The overheat protector switching electricity time is about 1: 10, and compressor protector can reach 1: 50.
Claims (2)
1, a kind of compressor protector; it is characterized in that it is made up of delay circuit, relay and lead; said delay circuit one end is connected in series compressor thermal protector according to lead; its other end is connected in series relay according to lead, and the contact of the relay of control compressor start time-delay is serially connected on the thermal protector other end of compressor according to lead.
2,, it is characterized in that said delay circuit can take conventional transistor delay circuit by the said a kind of compressor protector of claim 1.
