Abstract
The invention provides an adjustable lightning arrester bracket and a gas insulated switchgear. The adjustable lightning arrester bracket comprises two U-shaped plates, two vertical aluminium profiles, a horizontal cross beam and a plurality of fasteners, wherein the vertical aluminium profiles can slide along the U-shaped plates in the depth direction of a switch cabinet for adjustment, and the horizontal cross beam can slide up and down along the vertical aluminium profiles in the height direction of the switch cabinet for adjustment. Under the conditions of different number of cables, different lengths of cable heads, different lengths of head parts of rear insertion lightning arresters as well as different lengths and heights of the rear insertion lightning arresters which are configured in an external conical gas insulated switch cabinet, the rear insertion lightning arrester can be supported by adjusting positions of the horizontal cross beam in the height direction and depth direction of the switch cabinet, thereby reducing the risks of epoxy resin cracking of an external conical casing pipe, lightning arrester insulation breakdown and internal arcing of the external conical gas insulated switch cabinet.
Description
Technical field
The invention belongs to power product technical field, be specifically related to a kind of adjustable surge arrester support device, when the cable radical that tapered gas insulation switch cabinet configures, cable end length and rear plug in lightning arrester length and highly all different, can meet support fixing after plug in lightning arrester.
Background technology
Figure 1 shows that a kind of circuit breaker air chamber and cable vault's schematic diagram of existing interior tapered gas insulation switch cabinet, its circuit breaker air chamber 11 is arranged on cable vault 12.The parts such as cable inner cone sleeve pipe 111, block current transformer 112 and lightning arrester inner cone sleeve pipe 113 are comprised in circuit breaker air chamber 11.Operationally, each cable inner cone sleeve pipe 111 can only connect unit cable 121, and lightning arrester inner cone sleeve pipe 113 connects lightning arrester 122 separately.On the one hand because block current transformer 112 price is higher; It is arranged in circuit breaker air chamber 11 on the other hand, when safeguarding and replace, needs first gas recovery to open breaker chamber 11 again.So interior tapered gas insulation switch cabinet has use the shortcoming that many, the block current transformer prices of sleeve pipe quantity are high, safeguard inconvenience.
Figure 2 shows that a kind of existing circuit breaker air chamber of outer tapered gas insulation switch cabinet and the schematic diagram of cable vault, its circuit breaker air chamber 21 is arranged on cable vault 22.The feature of this switch cubicle is: its outer cone sleeve pipe 221 level is arranged on circuit breaker air chamber 21 housing, and single outer cone sleeve pipe 221 can connect multi-cable head 223 and one and plug in lightning arrester 224 afterwards; Punching current transformer 222 not only has price advantage than block current transformer 112, and it passes outer cone sleeve pipe 221 and is arranged on outside circuit breaker air chamber 21, does not need gas recovery and opens circuit breaker air chamber 21 when safeguarding and replace.So outer tapered gas insulation switch cabinet has use the advantage that sleeve pipe quantity is few, punching current transformer price is low, easy to maintenance.
Outer tapered gas insulation switch cabinet is as shown in Figure 2 without design and installation surge arrester support, and its external force suffered by outer cone sleeve pipe 221 has: the gravity of cable end 223, cable 2231, rear plug in lightning arrester 224; Pulling force downward during installing cables 2231; The electric power of lightning arrester 224, cable end 223, cable 2231 and outer cone sleeve pipe 221 is inserted after when switch cubicle runs.On the one hand, because rear plug in lightning arrester 224 is without stent support, the moment loading taper bushing root 2211 outside that above-mentioned external force produces, increases the risk of outer cone ferrule boot 2211 epoxy resin cracking; On the other hand, because rear plug in lightning arrester 224 is without stent support, the external force such as gravity, electric power makes the insulation coordination face unbalance stress in rear plug in lightning arrester head 2241, thus causes insulation coordination face to occur air areola, makes its insulation property reduce and insulation breakdown occurs.The insulation breakdown of outer cone ferrule boot 2211 epoxy resin cracking and rear plug in lightning arrester head 2241 will make switch cubicle short circuit and inner arcing will occur.
The outer cone sleeve pipe 221 of outer tapered gas insulation switch cabinet as shown in Figure 2 install cable radical, cable end length, rear plug in lightning arrester length with highly all may be different, the superposition of these sizes makes lightning arrester bottom bolts 2242 different in the position of the depth direction of switch cubicle, short transverse.
Therefore, outside on tapered gas insulation switch cabinet, be starved of a kind of adjustable surge arrester support, avoid that external conical sleeve tube epoxy resin ftractures, lightning arrester insulation punctures and the occurrence risk of inner arcing.
