Abstract
The utility model relates to signal device fields, and is particularly suitable for flash units which use energy saving signal lamps with long service life in power plants and substations with DC operation. The utility model is composed of a sensitive starting element and a flashing component, solves the problem that the original flash unit is not adapted to the energy saving signal lamp with long service life, and can directly substitute the original flash unit.
Description
The utility model relates to the flasher that adopts long service life energy-saving signal lamp in the generating plant in telltale field, particularly dc operation and the electric substation.
Owing to develop AD series long service life energy-saving signal lamp, long being widely used on industrial and mining enterprises and the household electrical appliance of, life-span little because of its power consumption is as aspects such as high and low voltage switch cabinet, control flow (platform), Machine Tool Electric Appliances in recent years.AD series long service life energy-saving signal lamp is compared with XD series of signals lamp, and direct current series is general energy-conservation about 90%, and exchanges series energy-saving up to 99%.Promoting the use of and obtain quite huge economic benefit and social benefit, is the desirable renewal product of XD series of signals lamp.
But, just because of the energy-conservation especially reason of AD series energy-saving signal lamp, because AD series of signals lamp loop resistance is big about 10 times than XD series of signals lamp, can't start original flasher, make it not to be suitable in the breaker control circuit of the light supervision of adopting original flasher.Therefore, will limit energy-saving signal lamp in the electric substation of dc operation and the application in the generating plant as not changing this situation.This can cause very big energy dissipation undoubtedly.
The purpose of this utility model is the flasher that will provide in the dc operation system that uses in a kind of generating plant and the electric substation in the breaker control circuit that the light that adopts long service life energy-saving signal lamp monitors.
The purpose of this utility model is achieved in that relay and the contact (3) thereof that sensitive starting relay and normal opened contact (1), dropping resistor (2), charging resistor (4), charge and discharge capacitance device (5) is installed, plays schillerization in relay1 case, constitute the energy-saving signal lamp flashing relay, and then constitute the long service life energy-saving signal lamp flasher.
Owing to adopt sensitive starting relay (1) to make new flashing relay can be applicable to the long service life energy-saving signal lamp of high internal resistance low energy consumption.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Describe the details of the concrete device that the utility model proposes in detail below in conjunction with accompanying drawing.
Accompanying drawing is the electrical principle wiring of the utility model long service life energy-saving signal lamp with flasher, is new flashing relay electrical wiring in the frame of broken lines.
This device comprises:
(1) the sensitive starting relay of relay (1) is the key element of this device, and its action current is between 2～5 milliamperes.One of sensitive starting relay (1) terminates to the anode of control power supply, and the other end is received on flash of light bus (+) SM by dropping resistor (2), the charge circuit of the normal opened contact of sensitive starting relay (1) pilot relay (3).
(2) resistance resistance (2) is the dropping resistor of sensitive starting relay (1), and the resistance of change resistance (2) can be adjusted the sensitivity of flasher.
(3) relay relay (3) plays schillerization with charging resistor (4) and charge and discharge capacitance device (5), and it is a small-sized high power low-voltage direct relay, and embodiment selects the JQX-13F type for use.Be connected to the anode of control power supply behind the changeover contact (3) of one end of relay (3) by itself, be connected to the negative terminal of control power supply behind the normal opened contact of the other end by charging resistor (4) and sensitive starting relay (1).Charge and discharge capacitance device (5) is also followed in the two ends of relay (3).
(4) resistance resistance (4) is the charging resistor in relay (3) and capacitor (5) loop.The resistance of change resistance (4) can be adapted to different operating voltage.
(5) capacitor electrode container (5) is the charge and discharge capacitance device in relay (3) loop, and the electric capacity of capacitor (5) also will suitably be adjusted when the resistance of resistance (4) changes, and is less to keep flashing rate to change.
The utility model long service life energy-saving signal lamp is as follows with the flasher principle of work:
When the position of a certain isolating switch and its gauge tap not at once, promptly flash of light bus (+) SM is switched to negative supply by " not corresponding " loop, the wire loop of the sensitive starting relay (1) of flashing relay SGJ is switched on, its normal opened contact (1) closure, the resistance (4) of connecting on the capacitor (5) of parallel connection and the coil on the coil of engage relay (3) and the coil charges, the voltage that is added on relay (3) coil rises gradually, relay when voltage reaches its working value (3) action, the normally closed contact of the changeover contact (3) that is in series with relay (3) coil is opened the charge circuit of block system relay (3), the normal opened contact closure of while changeover contact (3), positive supply directly is added on flash of light little bus (+) SM, the signal lamp in " not corresponding " loop is emitted a brilliant light.Because the closure of relay (3) normal opened contact makes sensitive starting relay (1) wire loop lose voltage, its normal opened contact (1) returns under no current state simultaneously.Capacitor this moment (5) begins discharge through the coil of relay (3), guard relay (3) is at operating state, but the voltage on the coil of relay (3) descends gradually, when voltage drop is low to moderate the return voltage of this relay, relay (3) involution, the normal opened contact of its changeover contact (3) is opened, the normally closed contact closure, voltage on (+) SM bus of flashing relay SGJ makes the signal lamp deepening along with reduction.Because the normal opened contact of the changeover contact (3) of relay is opened, sensitive starting relay (1) wire loop is connected again by " not corresponding " loop, its normal opened contact (1) closure, the charge circuit of engage relay (3), repeat said process, make the signal lamp that is connected on flash of light bus (+) SM send continuous flash of light.
Whether intact in order to test flasher, installed test button YA and signal lamp BD.Normally closed contact through YA when signal lamp BD is flat is connected between the positive-negative power, works to monitor flasher direct supply and fuse 1RD and 2RD.When pressing test button YA, BD promptly switches on flash of light bus (+) SM, and the normal opened contact of the YA of this moment is equivalent to " not corresponding " loop, and BD is equivalent to the position indicator of isolating switch, if flasher is working properly, then BD promptly sends tangible flash of light.
