Description

A kind of electrical equipment time-delay mechanism

Technical field

The utility model belongs to power control unit technical field, more particularly, to a kind of electrical equipment time-delay mechanism.

Background technology

Current delay circuit constitutes RC discharge and recharges delay principle using attached discrete component outside transistor or integrated circuit mostly Design, although delay precision is high but circuit structure is relative complex, relatively cumbersome in failure and maintenance process.This delay Device design only need to be with 2~3 elements, simple in construction without using transistor and integrated circuit, reliable operation, and reference time delay is about In one minute, and can be with according to rough adjustment is needed, for delay need to be used and to the less demanding electrical equipment of timing accuracy and equipment It is applicable very much.

The content of the invention

The purpose of this utility model is the deficiency for improving prior art and provides a kind of suitable for needing preheating before start With prepare, the load appliance or equipment electrical equipment time-delay mechanism of the life's work that switches on power again after delay, with simple in construction, steady It is fixed reliable, can merge the characteristics of one quantifies to produce with relay.

The purpose of this utility model is achieved in that a kind of electrical equipment time-delay mechanism, including AC power, relay, neon Bubble, is characterized in the N line contact relays JD in two-phase alternating current source coil one end, the other end of relay JD coil succeeds electricity A device JD normally opened end and the common port with neon bulb HL, normally opened end is corresponding closes for this of neon bulb HL another relay termination JD Close end, the L lines of the corresponding middle termination two-phase alternating current of the closed end, intermediate ends, the normally opened end difference of remaining group of relay JD Two ends for connecing workload.

Can be it is characterized in that being parallel with electric capacity at neon bulb HL two ends to further realize the purpose of this utility model C。

Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model uses neon bulb Interior bonding jumper expanded by heating completes the principle of certain time needed for switching on power to reach work in the purpose of delay, adjustment neon bulb The electric current of work can also change the time of bonding jumper connection, so as to reach the purpose of adjustment delay；In neon bulb two ends low capacity in parallel Electric capacity can change the size of current in neon bulb, so as to reach the purpose of adjustment delay time, can be adjusted flexibly and use.Present apparatus knot Structure is simple, and element used is reliability and durability, with low cost；And one can be merged with relay quantify production, as there is specific function Component.

Brief description of the drawings

The utility model is described in further details with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is another structural representation of the present utility model.

Embodiment

A kind of electrical equipment time-delay mechanism, reference picture 1 is the N line contact relays JD in two-phase alternating current source coil KT one end, after Electrical equipment JD can use the relay of different number group contacts as needed, and the present embodiment enters by taking the relay of four groups of contacts as an example Row explanation, relay JD coil KT another relay termination JD normally opened end KA1 and the common port with neon bulb HL, neon bulb HL Another relay termination JD corresponding intermediate ends KO1 of normally opened end KA1 corresponding closed end KM1, closed end KM1 connect two-phase The L lines of alternating current, delays time to control line holding relay JD one group of load is relay JD its excess-three group intermediate ends, normally opened End is respectively used to connect the two ends of load, that is, loads intermediate ends KO4, the normally opened end KA4 of FZ4 two ends respectively with relay JD and connect Connect；Intermediate ends KO3, the normally opened end KA3 of FZ3 two ends respectively with relay JD is loaded to be connected；Load FZ2 two ends respectively with after Electrical equipment JD intermediate ends KO2, normally opened end KA2 connections.

In order to adjust delay time, reference picture 2 is parallel with electric capacity C at neon bulb HL two ends, and electric capacity C uses CBB electric capacity, From it is pressure-resistant be not less than 400V, capacity 0.01uf~0.1uf CBB electric capacity is connected in parallel on neon bulb two ends to be best, because of delay time Influenceed substantially by neon bulb model, different model delay time can be different, can be adjusted flexibly and use.

Present apparatus relay JD is powered using 220V AC powers, and relay JD loads for four tunnels, in four dpdt double-pole double-throw (DPDT) patterns, Four tunnels are closure state on one side under normality, and after switching on power, four-way switch is closed to opposite direction, complete load circuit and connect.

When in use, the N-terminal of relay JD working powers 220V exchanges connects in actuating coil KT one end, L terminations the present apparatus Between at point KO1, when working power is connected, neon bulb HL lights and produces heat, and heat to be put aside causes metal in neon bulb HL When bar expanded by heating connects the other end, instantaneous short circuit inside neon bulb HL, power supply is loaded directly on relay JD coil KT, after Electrical equipment JD normally opened end KA1, KA2, KA3, KA4 respectively with intermediate ends KO1, KO2, KO3, KO4 adhesive, therefore working power L ends By KO1, KA1 and relay JD coil KT one end is joined directly together, and power supply is locked and maintains working condition, and neon bulb branch road is presented Bypass condition, no longer works.The present apparatus completes to switch on power required certain time using bonding jumper expanded by heating in neon bulb HL Principle so as to reach that the electric current of work in the purpose of delay, adjustment neon bulb HL can also change the time of connection, so as to reach tune The purpose of whole delay；At neon bulb HL two ends, shunt capacitance C can change the size of current in neon bulb HL, so that when reaching adjustment delay Between purpose, immediate current is larger when being connected because of large bulk capacitance and charging interval length easily makes neon bulb HL work abnormal, passes through The pressure-resistant CBB low capacity electric capacity for being not less than 400V is preferably selected in experiment（0.01uf~0.1uf）Neon bulb HL two ends are connected in parallel on, can be flexible Adjustment is used.

The present apparatus is simple in construction, and element used is reliability and durability, with low cost；And one quantization life can be merged with relay Production, is used as the component for having specific function.
