Description
Technical field
The utility model belongs to appliance switch technical field, is specifically related to a kind ofly power supply and load isolation come in mine anti-explosion electrical equipment and can change the device of phase sequence, and can be with and carry a disjunction.
background technology
Small-sized insulating phase-change switch used in the market, be 80A in rated current, under 1140V voltage status, isolating switch can only be simple use as break-up device, do not possess extra auxiliary contact, scram button and corresponding controlling organization must be increased in addition for disjunction control loop power supply.Which adds cost, in use too increase fault point simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, simultaneously in order to meet the need of market, and the novel insulating phase-change switch of one proposed.
The utility model is achieved in that novel insulating phase-change switch, comprises scale high-voltage rotary isolating, it is characterized in that fixing a cam in the rotating shaft of scale high-voltage rotary isolating, establishes travel switch at cam correspondence position; Described cam can automatic rotation 45 degree to the left or to the right, by the button spindle of cam rotary push travel switch.
Usually, described travel switch comprises binding post, normally closed fixed contact, often opens fixed contact and button spindle, and described button spindle one end is provided with spring, and button spindle is provided with normally closed fixed contact, often opens dynamic contact mechanism corresponding to fixed contact.
The utility model fixes a cam in the rotating shaft of original small rotary insulating phase-change switch, when insulating phase-change switch is got to forward or is reverse, fixing cam can left or to the right automatic rotation 45 degree, origin-location is reverted to by crush stroke shift knob bar band moving contact, the normal battle of travel switch is closed, and normally closed point is opened.Travel switch is synchronous with insulating phase-change switch, and when insulating phase-change switch gets to on-position, travel switch closes (disconnection); During insulating phase-change switch disjunction, travel switch disconnects (closing).
The utility model is mainly useful in rated voltage 1140V, in electric current 80A and following various electric equipments, uses as disjunction three phase mains.Can be with and carry disjunction, change phase sequence.
Insulating phase-change switch of the present utility model can not only meet the various functional requirements of common isolating switch, but also adds one group of auxiliary normal battle and normally closed point, can open and close synchronous with insulating phase-change switch.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of embodiment insulating phase-change switch; Fig. 2-4 is a, the b of insulating phase-change switch in embodiment respectively, c tri-kinds of working state schematic representations; Fig. 5 is travel switch structure schematic diagram in embodiment.
In figure, 1-cam; 2-travel switch; 3-cam standing screw; The rotating shaft of 4-insulating phase-change switch; 2-1-binding post; 2-2-spring; 2-3-dynamic contact mechanism; 2-4,2-8-normally closed fixed contact; 2-5,2-7-often open fixed contact; 2-6-button spindle.
In Fig. 2-4, a is forward open mode; B is off state; C is negative open configuration.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Embodiment: novel insulating phase-change switch as shown in Figure 1, mainly comprises scale high-voltage rotary isolating, it mainly improves is fix a cam 1 by cam standing screw 3 in the rotating shaft 4 of scale high-voltage rotary isolating, establishes travel switch 2 at cam 1 correspondence position; Described cam 1 can automatic rotation 45 degree to the left or to the right, by the button spindle 2-6 of cam 1 rotary push travel switch 2.
In embodiment, travel switch 2 structure as shown in Figure 5, comprise binding post 2-1, normally closed fixed contact 2-4 and 2-8, often open fixed contact 2-5 and 2-7 and button spindle 2-6, button spindle 2-6 one end is provided with spring 2-2, and button spindle 2-6 is provided with normally closed fixed contact 2-4 and 2-8, often opens dynamic contact mechanism 2-3 corresponding to fixed contact 2-5 and 2-7.
Embodiment operates like this: see accompanying drawing 2-4 and Fig. 5, when insulating phase-change switch is in open position, as the state of Fig. 3-(b), now the dynamic contact mechanism 2-3 of travel switch and fixed contact 2-5 and 2-7 that often open of travel switch connects, disconnect with normally closed fixed contact 2-4 and 2-8, this often opens fixed contact 2-5 and 2-7 and exports as close node, and normally closed fixed contact 2-4 and 2-8 exports as opening node.According to design needs, contact signal can be drawn by binding post 2-1, in the middle of the control loop being linked into equipment.When insulating phase-change switch is in the close position, as the state of Fig. 2-(a), now the dynamic contact mechanism 2-3 of travel switch and normally closed fixed contact 2-4 and 2-8 of travel switch connects, with often open fixed contact 2-5 and 2-7 and disconnect, now normally closed fixed contact 2-4 and 2-8 exports as close node, often opens fixed contact 2-5 and 2-7 and exports as opening node.When insulating phase-change switch is in Fig. 4-(c) state, the state of travel switch is consistent with Fig. 2-(a), and just the major loop phase sequence of insulating phase-change switch is different.
